Introduction

If you are at JR Sakura Station, the place, where the castle ruins are located, it may look simple at first. However, if you go there by walking up on the slopes, you will be surprised to see the spacious area on the top. Visitors coming from other places may feel the same way, too.

From Main Gate to Main Enclosure

Let us go from the ruins of the main gate to the center of the castle. Unfortunately, only a part of the earthen walls remains today.

There were some large enclosures inside the gate, such as Higashi-so-kuruwa. They were turned into schools, parking lots, and a square. There is also Sakura Castle Park control center in front of the square, which shows some exhibitions of the castle. The square had the main hall for the lord and another one for the retirement residence of Masayoshi Hotta at the end of the Edo Period.

You will eventually reach the center of the castle, which has been turned into Sakura Castle Park. You will first see the remaining large dry moat. It looks beautiful, covered in grass, however, it must have been deeper and more fortified in the past.

You will next reach the ruins of the third gate, which was the first gate towards the center. The third enclosure is inside of the gate, and it was the residential area for the senior vassals in the past. You will find a mini crater in the enclosure. This is the trace of another dry moat, which has been filled. If you go further, you will see the statues of Townsend Harris and Masayoshi Hotta who tried to open Japan to the rest of the world.

Then, you will reach the ruins of the second gate, the entrance of the second enclosure. The enclosure had had the first main hall for the lord before the one outside the third enclosure was built. There were also the rice warehouses in the back of the enclosure. You can still see its stone foundations there, too.

You will eventually reach the main enclosure after going across the dry moat of the enclosure. there are the ruins of the first gate.

Climbing down from Main Enclosure

The main enclosure is all surrounded by earthen walls, so you may feel like you are being wrapped up. This area is the western edge of the plateau. There was the other main hall inside, however, it was rarely used just for ceremonies. This was because it was considered exclusive for the shoguns.

You can walk on the earthen walls around the enclosure. If you walk from the first gate ruins on the earthen walls, you will pass by the ruins of Do-yagura (the copper turret). The turret had a mysterious tradition. It says that the turret was originally built by Dokan Ota, the founder of Edo Castle, called “Shoyoken”, and moved from the castle. However, we cannot confirm whether or not the turret was moved from Edo Castle. However, if it had remained, it would have become a National Treasure of Japan.

The old photo of the turret, from the signboard at the site, as you can see, carpenters were removing the roof tiles partially

The miniature model of the turret, exhibited by the Sakura Castle Park control center

If you go further, you will eventually reach the earthen base of the main tower.
The tower was directly built on the base and its outside walls leaned on the earthen walls of the enclosure. That was why people saw the tower three-leveled from the outside but four-leveled from the inside. The tower was used as the warehouse for weapons. It was unfortunately burned down after a thief robbed it of guns and left his lantern there.

There are the other ruins of the corner turret in the enclosure. The turret also has the tradition which says it originally came from Motosakura Castle. That may have been the reason why it deteriorated sooner than the others and was renovated during the Edo Period.

Let us next get out of the enclosure through the ruins of the back gate and climb down the slopes of the plateau. The slopes are steep which made the castle fortified. You will eventually see some trails on the mid slopes, which are the belt enclosures of the castle. The enclosures were said to have originally been dry moats and were changed to the trails by being filled naturally. If you look up the main enclosure, you will realize it is protected by the natural terrain even though it doesn’t have stone walls.

Climbing down the slopes of the plateau, please be careful when climbing down because it’s very steep

You will eventually arrive at the foot of the plateau and see the southern barbican enclosure. If you go around the enclosure, you will see it is still surrounded by water moats. It looks very defensive and cool! If you enter the enclosure as well, you will see the outside which you walked around on.

I recommend you to go back to the belt enclosure and walk on it to the other western barbican enclosure. The enclosure still has its earthen walls and water moats in good conditions. There is the only remaining building at its entrance, called Yakui-mon gate. However, No one knows for certain its original name and position, because it was moved multiple times from the current position that it is in now.

Looking at Umadashi system and Dry Moats

If you don’t mind, it may be better to walk around the plateau to another entrance from the north to the castle. It was called Tamachi-mon which was the back gate of the castle, on Atago slope. It is now the front gate of the National Museum of Japanese History. A large enclosure of the castle, called Shinoki-kuruwa has become the museum. The enclosure was originally used as Samurai residences and was turned into barracks for the Japanese Imperial Army before the museum. It has been used effectively because it is massive.

The floor space of the museum is about 35,000 square meters big. It exhibits the Japanese histories by classifying 5 different periods. If you want to look through all of them, you may have to spend all day long. It may be better to split up your visits to fully see everything.

Going back to the attractions of the castle, the Umadashi system has been restored near the museum. The system was a fortified square position in front of Shinoki Gate, which was surrounded by dry moats. The long side of the square is 121m long and the short side is 40m long, same as the original. The dry moats were originally 5.6m in depth but is only 3m in depth probably for safety reasons. The system is only connected by a narrow path to the gate. It was once filled by the Japanese Imperial Army before its restoration.

The Umadashi system in front of the Shinoki Gate Ruins

The Shinoki Gate Ruins have no buildings now, and its inside is the third enclosure. So, you can visit the second and main enclosures again. However, let us go to another place by walking down from the plateau again. It is a pond, called Uba-ga-ike, which means “The Pond of a Nursing Mother”. The name comes from a sad and unfortunate story. It says that one day, a nursing mother took the daughter of a senior vassal to the pond. However, she didn’t keep her eyes on the daughter, which lead to the daughter drowning in the pond She felt very sad and guilty about it, so, she decided to throw herself into the pond as well. For the castle, this pond divided the main gate and the back gate sides to force the defenders protect the castle quickly. It also became famous for Japanese iris and croaking sounds of frogs during the peaceful Edo Period.

The Uba-ga-ike Pond, Since the pond is covered in lotus leaves, it’s hard to see how deep it truly is

You can go back from the pond to the main gate ruins by passing through a path which was another dry moat. The path has a fork which still looks like the dry moat. If you go straight, you will eventually reach the entrance of the park near the gate ruins.

The fork on the right remains as a dry moat

Visiting Samurai Residences and Sakura Juntendo Memorial Building

Atter visiting the castle ruins, let us go to Sakura Samurai Residences. The residence area is in Miyakoji of Sakura City, which originally had middle-class warriors’ residences. However, the current area exhibits three different residences: one of the remaining one for middle class warriors, another one form high-class warriors and finally, the other one form low-class warriors. The last two residential areas were moved from other areas, making it accessible to the public for viewing.

Sakura Samurai Residences Street, Notice the samurai residential homes on the right

These residences were owned and maintained by the Sakura Domain like official residences. They were made differently by each warrior’s class. That was because of the class system as well as the budgetary restrictions of the domain. For example, the entrance of the high-class residence looks high in quality, but the others are simpler. The walls of the high class’s one used white plasters, while the others only used brown mud walls. The high and middle class’s ones used fine Tatami mats in their rooms, however the low class can only use simple mats without the edge decorations.

The low-class residence (its roof has been replaced with a modern style)

You should also try to walk along Hiyodori-zaka Slope near the residences, which was the commuting route to the castle. The route goes down on a trail, surrounded by bamboo trees, which looks exactly same as it used to.

We will finally go to Sakura Juntendo Memorial Building. It was originally built by Taizen Sato as his Rangaku (Dutch studies) school and clinic. Part of it opens to the public as a museum. The museum is about 2km away from the main gate ruins of the castle and was at the edge of the castle town. This is probably because Taizen was not an official doctor of the domain. A guide of the museum suggested to me another speculation. Taizen’s father was an agent in lawsuits who was against the policies of Tadakuni Mizuno, the top of the government. Therefore, Taizen might have had difficulties in his work in Edo City. He might also have been accommodated by Masayoshi Hotta. If it’s true, Sakura Juntendo was also like a place of refuge.

One of the exhibitions of the museum is the miniature model of the original buildings. You can see the buildings were so large. It is said that over one thousand students were there in total.

Another interesting exhibition is the original medical board which is hung on the top of the wall. The clinic mainly offered surgeries. However, the doctors didn’t use anesthesia because it was still dangerous at that time. Therefore, patients endured the pain because they wanted to get well after that.

The original medical menu, Notice the price of each procedures on the bottom of the medical board

The clinic is the origin of Juntendo University in Tokyo, one of Taizen’s successors who founded it. However, there is still the current Sakura Juntendo Clinic next to the museum. The spirits of Sakura are alive.

The plaque of Juntendo, It’s written in Chinese Characters (Kanji)

My Impression

Honestly, at first, I thought the castle park looked like a natural park. However, the more I looked around, the more my impressions changed. Currently it’s trendy for cities to revive castles across Japan. I think Sakura City does not need to ride the boom. This is because the city has already preserved the land of the castle as the park. The city can take enough time and be patient when developing it further. The important thing is preserving it as accurate as possible. In addition, you can still enjoy the castle ruins even without its visible buildings. So I highly recmmend you visit Sakura Catle in the future!

That’s all. Thank you.

Back to “Sakura Castle Part1”

20.Sakura Castle Part1

Sakura Castle was located at the current Sakkura City of Chiba Prefecture. The castle was built as the home of the Sakura Domain during the Edo Period, which is the origin of the city. The areas around the city had many other castles until the Sengoku Period and some of which were very important.

Location and History

Sakura Castle was located at the current Sakura City of Chiba Prefecture. The castle was built as the home of the Sakura Domain during the Edo Period, which is the origin of the city. The areas around the city had many other castles until the Sengoku Period and some of which were very important. For example, there was Usui Castle in the western part of the city, where the battle of Usui Castle happened back in 1566. Kenshin Uesugi, who tried to rule the whole Kanto Region, attacked the castle but failed. There was also Motosakura Castle in the eastern part, which was the home of the Chiba Clan. Usui Castle was a branch of the clan. Cuttently, this castle is called “Motosakura” but back then, it was called “Sakura Castle”. So therefore, Sakura Castle was the former name of Motosakura Castle. This article will explain the formative years of Sakura Castle including the formation of Motosakura Castle, which should make it easier for people to better understand the history.

Formative Years of Sakura Castle

The Chiba Clan had owned Shimosa Province, which was the northern part of Chiba Prefecture, since the end of the ancient times. The most famous person of the clan would be Tsunetane Chiba who supported the launch of the Kamakura Shogunate at the end of the 12th Century. Their home, Inohana Castle, was located at the current Chiba City for a long time. However, the castle was destroyed when many battles occurred in the 15th Century during the Sengoku Period. The clan decided to rebuild their new home in another location, which would be called Motosakura Castle. The castle was on the Shimosa plateau and was surrounded by Inbanuma Lake and other waterlogged areas. Its location was much more fortified than before and more convenient for water transportation. The lake was also much larger than now, where people could easily access Kasumigaura Lake and other great rivers. The wide water area was even called Katori-no-umi, which means the Katori inland sea.

The situation changed during the 16th Century. The Hojo Clan was invading the Kanto Region from the west. On the other hand, the Satomi Clan also got the power from the south (Boso peninsula). The Chiba Clan wondered what to do and they eventually allied with the Hojo Clan. That’s why Kenshin Uesugi, who would help the Satomi Clan, decided to attack Usui Castle, a branch of the Chiba Clan. The victory of the clan was partially due to the Hojo Clan’s help. As a result, the Hojo became more effective to the Chiba Clan. As for the home of the clan, Chikatane Chiba, who was the lord of the clan before the battle, originally planned to move his home from Motosakura to another. The new land for his new home later became Sakura Castle, which was called Kashima Castle then. Mysteriously, he died in 1533, which ultimately canceled his plans of moving the castle.

The location of the castle, Notice the smaller Inbanuma Lake on the left next to Usui Castle. This important river used to span much larger that what the current map is showing. It used to be part of a much larger body of water.

The Hojo Clan interfered in the internal affairs of the Chiba Clan at the end of the 16th Century. For instance, Ujimasa Hojo married his daughter to Kunitane Chiba, the lord of the clan. The Hojo Clan allowed Kunitane to resume the construction of Kashima Castle but failed to do so because the lord was killed again. Ujimasa next married his son to Kunitane’s daughter, in order to be the successor of the clan. It was said that Kashima Castle was finally finished for the new home of the couple.

However, it is difficult to confirm whether these records are the factual, as Sakura Castle was built on the old Kashima Castle. The few discovered old dry moats at the site proved that they were at least trying to build the castle there. So, why did the Chiba and Hojo Clans want to move there again and again? One of the reasons would be that the land for the new castle was much larger than the old one. For the Hojo Clan, another possible reason may have been to protect their territories from the potential invasions by Hideyoshi Toyotomi from the west. The plateau, where the new castle was built on, had steep slopes and was surrounded by rivers towards the direction. That would have had a very defensive fort against the invasion. However, the Chiba Clan was eventually fired by Hideyoshi, after their master, the Hojo Clan was defeated at the battle of Odawara Castle in 1590.

Toshikatsu Doi builds Sakura Castle

After the Battle of Odawara Castle, several lords were assigned one after another by Ieyasu Tokugawa who was the founder of the Tokugawa Shogunate. In 1610, Ieyasu ordered his retainer, Toshikatsu Doi to stay in Motosakura Castle and to build a new home at the former location of Kashima Castle, which would eventually be called, Sakura Castle. The new castle was supposed to support Edo Castle, the home of the shogunate. If Edo Castle was attacked by enemies from the west, the shogun could escape from his home to Sakura Castle towards the east. Sakura Castlewas situated in a great location that had very strong natural defense.

Toshikatsu served three generations of the shoguns: Ieyasu, Hidetada, and Iemitsu. He was one of the most important senior vassals for them and established the system of the government. He was born in 1573 when Ieyasu was only a warlord during the Seongoku Period. There are some theories about who his father was.
The first one is that Toshimasa Doi was his father, according to the official family trees by the shogunate.
The second one claims that he was a son of Nobumoto Mizuno who was a brother of Odai, Ieyasu’s mother, according to the official history books of the shogunate. Odai originally came from the Mizuno Clan.
The last theory is the most surprising theory, it was said that Toshikatsu was an illegitimate son of Ieyasu, according to the official trees of the Doi Clan.
Each theory has substantial evidence, however only one theory can be true. Why were there different theories?

The Portrait of Ieyasu Tokugawa, attributed to Tanyu Kano, owned by Osaka Castle Museum (licensed under Public Domain via Wikimedia Commons)

Recent studies believe the followings. Toshikatsu has a short sword where the family crest of the Mizuno Clan was engraved. It was passed down from Odai to Ieyasu who gave it to Toshikatsu. That meant Toshikatsu was Ieyasu’s son. However, it was a very know fact, which was not recorded officially. That’s why the official family trees simply say Toshikatsu was a biological son of the Doi Clan (in fact, adopted). After that, Toshimasu Doi, who was a grandson of Toshikatsu, was worried about the declining reputation of his clan. He thought that he should settle the mystery of his grandfather to gain a stable position for the clan. His decision was that he would announce that Toshikatsu was a son of the Mizuno Clan by using its family crest on the sword. The writers of the official history books probably heard about it. Finally, Toshisato Doi, the 8th lord of the clan, was asked as to who Toshikatsu’s mother was by the shogunate. Toshisato decided that he would answer by telling the truth and put it on his clan’s official trees. However, the shogunate couldn’t accept it because the matters of Ieyasu were too serious to change for them. As a result, the three theories certainly unchanged today. As for Toshikatsu himself, he became a close vassal of Hidetada, who was the successor of Ieyasu, when Toshikatsu was only 7 years old. No matter who his father was, it’s no mystery that he was a very talented person.

The portrait of Toshimasu Doi, owned by Jojoji Temple (licensed under Public Domain via Wikimedia Commons)

When Ieyasu established the shogunate, his most influential retainers were the Honda and the Okubo Clans. However, they often had internal conflicts with each other. As a result, Masazumi Honda survived when Hidetada became the 2nd shogun. Hidetada didn’t want to let Masazumi have more power. He and his close vassals, including Toshikatsu Doi, decided to trick Masazumi. When Masazumi went on a business trip from his home, Utsunomiya Castle, to another castle where he was told about his replacement. That’s the reason Masazumi would not be able to raise a rebellion. In fact, that’s the same way Masazumi excluded the Okubo Clan earlier on. Toshikatsu must have joined the careful planning of the strategy. He continued to serve the shoguns, including the third shogun, Iemitsu, for a long time. He also contributed to the shogunate by building the group guidance system of the shogunate. The system would avoid relying on individual abilities and having internal conflicts so much like the shogunate had used to.

In reality, Toshikatsu survived these internal conflicts. Therefore, people sometimes viewed him as a Machiavellian. On the other hand, he was a well-informed and kind person whom the shoguns, his colleagues, and even foreign merchants often relied on. That may be one of the reasons for his longevity. He was also the founder of the Sakura Domain and built Sakura Castle in over 7 years, which was eventually completed in 1616.

Features of Sakura Castle

Sakura Castle, which was built on a large plateau, had several distinctive features. First, the castle wisely used the natural shapes of the plateau. The plateau was basically a natural hazard, which was about 20m above the foot of the hill and surrounded by Takasaki and Kashima Rivers. The main enclosure was built at the western edge of the plateau, and other enclosures were built around it. Large dry moats and the main gate were also constructed to the east for fortification. The Samurai residences and the castle town with Narita Road were built over the gate. Overall, the castle and town were all created on the plateau.

The old photo of the main gate, from the signboard at the site, Notice how small the people are. The gate was so much bigger compared to modern gates today

Secondly, the castle foundations were all made from soil, not using stone walls. When the battle of Odawara Castle happened, Hideyoshi Toyotomi built a castle made of pure stone walls, called Ishigakiyama Castle, for the first time in the Kanto Region. Since then, similar castles, such as Edo Castle, were built in the region. However, Sakura Castle kept the traditional method of the region, using only soil. Other castle used the same method, such as Kawagoe and Utsunomiya Castles. On the other hand, the castle had some of the latest defensive systems at that time. There were two defensive positions, called Umadashi, in front of the gate of the third enclosure. There were also huge enclosures outside the third enclosure, which could accommodate lots of soldiers and was used as a parade ground. Furthermore, the belt enclosures were built on the slopes of the plateau where the defenders were able to move easily. Finally, the enclosures connected to two barbican enclosures outside the plateau.

The final feature is about the buildings of the castle. There was the main tower in the main enclosure, which was about 22m high and had three levels (four floors). It was extremely rare for that type of castle to be built at that time. (The shogunate basically didn’t allow new castle constructions after its rules were established.) The tower was said to have moved from Edo castle. Its details are unknown, however, because it was unfortunately burned down by an accidental fire during the Edo Period. Historians speculate that it was similar to that of Koga Castle, which Toshikatsu also built later on. There were also Do-yagura (Copper Turret) and Sumi-yagura (Corner Turret) in the main enclosure. The enclosure also had the main hall inside but was barely used. This was because it was once used by Ieyasu Tokugawa, so it was considered exclusive to the shoguns. Instead, the lord of the castle lived in the main hall of the second enclosure. Atter the hall deteriorated; a new hall was built outside the third enclosure.

Masayoshi Hotta comes up with an idea to Open the Country from Sakura Castle

After Toshikatsu Doi moved to the Koga Domain in 1633, several lord families ruled the Sakura Domain during the Edo Period. In particular, the Hotta Clan owed the domain and castle for a long time until the end of the period. I will describe Masayoshi Hotta who was one of the lords and how he devoted his life to reforming and opening the country to the rest of the world. Masayoshi was born in 1810 and became one of the core members of the central government when he was 32 years old. However, he quit the position 2 years later because he didn’t really get along with Tadakuni Mizuno, the top of the government under the shogun. However, he kept in touch with his colleagues like Masahiro Abe and Naosuke Ii.

He also reformed the government of the Sakura Domain. He declared the reform to the retainers of the domain at the main hall in the third enclosure of Sakura Castle. One idea was to include the military system of the domain. He changed it to the western style and he allowed the soldiers to exercise in the castle. Another major change from the reform was that Masayoshi introduced the western medicine to the domain. He invited a famous doctor, Taizen Sato from Edo City, who opened a medical school, called Sakura-Juntendo. Lots of students gathered there from all around Japan, which gave Sakura the name Rangaku (Dutch studies) town similar to Nagasaki. (At that time, the western science was provided from the Netherlands, one of the few countries which had diplomatic relationship with Japan.) Masayoshi was also called “Ranpeki” which means a person who devotes oneself entirely to Dutch studies and way of life. As a result, the scenery of Sakura Castle and the town dramatically changed.

After the arrival of Matthew Perry’s fleet in 1853, Masahiro Abe, who was the top of the government, asked the country to vote on whether or not Japan should open the rest of the world. Despite Masayoshi’s wishes to open Japan, most people voted against it. Masayoshi was suddenly assigned the top of the government (the chief of the members of shogun’s council of elders) in 1855. However, the reason why Masayoshi was appointed the top official was still uncertain. One of his tasks was to negotiate with Townsend Harris, the council of the U.S. about the trade treaty. Masayoshi actively dealt with Harris because both of them really wanted Japan to open to the rest of the world. The treaty was still unfair, however. For example, Japan didn’t have autonomy to tariffs. On the other hand, Masayoshi decided to open Yokohama Port which would become a worldwide port even today.

Even after the deal with Harris was finalized, Masayoshi still needed to handle a more difficult task. It was to get approval of the treaty from many relative lords in the government. When Toshikatsu Doi was the top, the system was simpler than the period of Masayoshi. However, the system had completely changed. The result was that only 4 of the 18 relative lords supported it. Therefore, Masayoshi’s second option was to get approval from the emperor, which had ever not been done. It would be the most effective way to overrule the lords. He visited the imperial court in Kyoto in 1558 to persuade the emperor and the nobles but he failed. This was because the emperor Komei himself did not want to open the country to the rest of the world.

Masayoshi was unfortunately fired, and the matter of the treaty was contnued by Naosuke Ii. He went back to the hall of Sakura Castle and lived there until his retirement and until his death in 1864. After the Meiji Restoration, the castle was used as a base for the Japanese Imperial Army. The mission of the base was to guard the eastern areas of Tokyo, the new imperial capital and the former shogun’s capital. That meant the role of the castle was the same between the Edo Period and the Meiji Era. After World War II, it became Sakura Castle Park and part of the park is used as National Museum of Japanese Histories today. The location of the castle is very suitable for such a large museum.

23.Odawara Castle Part3

I introduced the histories and features of Odawara Castle until the Sengoku Period in the previous articles. In this article, I will talk about the histories and features of the castle starting from the Edo Period to the present time. The catchphrase of this article will be “Disaster Recoveries”.

Location and History

Period of Okubo Clan

After the Battle of Odawara Castle in 1590, Ieyasu Tokugawa who captured the Kanto Region chose Edo, not Odawara, as his home. However, he assigned his senior vassal, Tadayo Okubo to Odawara Castle instead as the founder of the Odawara Domain. That meant the castle was still important in order to protect the region from enemies at the western edge of the region. Tadayo lived in the castle while maintaining its stone walls. He used the main hall that the Hojo Clan built, and the Main Tower the clan may have built also. This was because the style of the tower was different from those of the castle later on, but there is no certain evidence of this. Ieyasu often stayed in Odawara Castle when he went hunting or looked around his territories. Despite the close relationship, Tadayo’s successor, Tadachika Okubo was fired by Ieyasu due to a minor violation in 1614. It was actually said that it was caused by the conflicts between the Okubo Clan and the Honda Clan that was another senior vassal family.

Period of Inaba Clan

The Odawara Domain was revived in 1632 when Masakatsu Inaba, who was a close vassal of the shogun, became the lord of the castle. He was also a son of Lady Kasuga who was the foster mother of the shogun. Masakatsu was expected to guard the barrier of Hakone near Odawara, which would be the defensive line of the Kanto Region. However, in the following year, Kanei Great Earthquakes happened and it destroyed most of the castle and the castle town. The Tokugawa Shogunate, which planned the shogun’s visit to Kyoto after staying in Odawara in 1634, rapidly launched the reconstructions of the castle. That concluded the basic style of Odawara Castle during the Edo Period. For example, the main tower was rebuilt like the current one, but not the same one. The main portion of the castle was all surrounded by stone walls. The main hall in the main enclosure was built only for the shogun. Therefore, the lord of the castle stayed in his hall in the second enclosure, which was called “Oyakata”.

The castle town was also developed as a transportation hub of Tokaido Road, one of the main roads in Japan. On the other hand, the range of the castle was reduced to only on the plain land, compared to that during the Sengoku Period. There were exemptions that some of the So-gamae structure were used as borders of the domain or the town. For instance, the eastern gate of the town to Edo, called “Edoguchi-mitsuke” used the So-gamae earthen walls. In the Yamanokami Ditch on the hill, guards monitored the border of the domain at the gate which was built there.

Period of Okubo Clan again

The Okubo Clan became the lord of the Odawara Domain (Odawara Castle) after the Inaba Clan moved to the Takada Domain in 1686. Tadatomo Okubo who was the lord of the clan supported the current shogun as a member of shogun’s council of elders. Few years later, the Genroku Earthquake occurred in 1703 which destroyed the castle and its town again. Mt. Fuji also erupted four years later, which was called “Hoei Eruption”, and its volcanic ash caused serious crop failure to the farms. The castle lost all its main tower and halls, but the shogunate didn’t help the domain in this case. As a result, it took as long as 18 years to restore them except for the main hall for the shogun which was not needed any more. The reconstruction of the main tower was a third generation, which survived until the end of the Edo Period. When the costal defensive system against possible invasions was needed, three batteries were built along the remaining earthen walls of the So-gamae structure beside the sea. However, they were unfortunately demolished until now.

Odawara Castle until Now

After the Meiji Restoration, Odawara Castle was abandoned and most of the castle buildings were scraped. Meanwhile, the stone walls of the main portion were still used as the base of an imperial villa. However, the Great Kanto Earthquakes, which happened on the 1st of September in 1923, destroyed the villa, the stone walls and the only remaining castle building, was the one-level turret of the second enclosure. This disaster had mostly erased the scenery of the remaining castle. The villa was eventually turned into Odawara Castle Park.
People in Odawara started to restore the castle in 1934 by rebuilding the stone walls and the turret of the second enclosure. The 4th main tower and its stone wall base was rebuilt in 1960. Since then, Tokiwagi-mon Gate in 1970, Akagane-mon Gate in 1997, and Umadashi-mon Gate in 2009 were restored to recreate their scenery during the Edo Period. They could be considered one of the disaster recoveries which the castle experienced again and again.

Features

From Third Enclosure to Second Enclosure

Past visitors to the castle would usually enter the castle from the main gate while current visitors would start from Ohoribata Steet beside the moat of the second enclosure. (Ohoribata means “beside the moat”) However, how about if we take another route instead? This route starts from the entrance to the ruins of Kodamon-guchi Gate beside the Odawara post office. It goes on the few remaining earthen walls of the third enclosure to the Ohoribata Street via the gate ruins. This gate had originally been the main gate of the castle during the Sengoku Period. It was said that Kenshin Uesugi attacked the gate first and followed by Shingen Takeda later on.

The moat of the second enclosure was originally a pond surrounding the castle, called “Large Pond” or “Lotus Pond”. The stone walls and the single-level turret over the moat were restored after the Great Kanto Earthquakes. The original stone walls, which were destroyed by the earthquakes, were much higher than the current ones.

If you enter the front entrance of the Odawara Castle Park, you will enter the Umadashi-mon Gate through the earthen bridge over the moat. This gate was the latest restored gate in the castle, using wooden materials. It has a square space, called Masugata, inside, which makes it tough for enemies to penetrate.

If you pass the gate and walk around the moat again, you will eventually reach the Akagane-mon Gate, which is the front entrance of the second enclosure. You will need to walk across the wooden bridge to go over the moat again, which comes from the castle’s defensive layout. The gate was also restored to its original conditions with the help of old photos, records, and the results of the excavations. This Masugata System looks stronger than The Umadashi-mon Gate, which is surrounded by stone walls and mud walls.

The inside of the second enclosure is mostly an empty space but had the main hall for the lord (during the Edo Period) and the imperial villa (during the Meiji and Taisho Eras).

Arriving at Main Enclosure

We will eventually reach the main enclosure from the second enclosure through Tokiwagi-bashi Bridge. There used to be the eastern moat surrounding the main enclosure under the bridge, however, it has been converted into an iris garden which you can enjoy if you walk down to the former bottom of the moat. You can also see many hydrangeas planted on the slopes of the enclosure during the summer season.

After crossing the bridge, you will finally enter the last gate, called Tokiwagi-mon. It was restored using concrete instead of wood. The original gate had the Masugata system as well, however, the final restoration lacks one side of the walls probably to make it more accessible for visitors.

There is the reconstructed main tower in the main enclosure. It is very large for a three-level tower which is 27.2m tall and about 39m tall (including the tower base). The tower has four floors inside. It is the seventh tallest main tower among the existing ones in Japan. It is the fourth generation of the main towers of this castle, which was built emulating the miniature model and records of the third generation. However, the fourth generation has the observation platform for visitors on top, which is different from the design of the third generation tower. For this reason, the current tower is regarded not as “restored” but rather “reconstructed”. The inside of the tower is used as a historical museum, which was renovated are reinforced with earthquake-proof technology back in 2016.

You can see views of Odawara in all directions from the platform, including where you’ve already visited.

Hopes for the Future and Lessons of the Past

If you get out of the main enclosure through the northern exit, you will reach Goyomai Enclosure. (Goyomai means “official stored rice”) Unfortunately, you can not enter it because of the excavations. Instead, you can see the panels around, which showcases what were found there so far. For example, the ruins of a stone pawed garden, including beautiful cut stones, during the Sengoku Period were discovered. The site was turned into warehouses for rice during the Edo Period, which originated the name of the enclosure. I’m looking forward to seeing this site again after it becomes more developed.

If you go to the southern slopes of the main enclosure, you can see a lot of large stones at the foot which collapsed during the Great Kanto Earthquakes. In fact, the stones were used for the stone walls which covered the top of the enclosure. Some of the stones are still connected to each other forming a curve. That means they slid down from the top to the foot keeping the form when the earthquakes happened. It must have been caused by the enormous strength of the earthquakes. The exhibitions made me realize how important being prepared for disasters is.

Finally, It may be a good idea to visit the southern moat nearby. It is also known as “lotus moat” which uses the same name during the Sengoku Period. You may be seeing the same scenery as people at that time, which shows the castle has a long history.

My Impression

There are a lot of attractions about Odawara Castle from the Sengoku Period to the present time. Maybe you will need more than one day to see all of them. The lords of the castle achieved many things. For instance, they constructed one of the greatest castles and rebuilt the main towers three times. These works were passed down from one lord to the next. It may look simple, but it is difficult to maintain. I speculate that if another disaster happens in the future to Odawara, people there will survive along with Odawara Castle. They could be a role model for other people under similar situations in the future.

That’s all. Thank you.
