今回はまず、岡山城に向かうコースを2つご紹介したいと思います。岡山駅から城の正面側に向かうコースと、旭川沿いを歩いて、城の裏門側に至るコースです。城に着いたら、天守に登ってみましょう。その後は、殿様気分で後楽園にも行ってみましょう。

岡山駅前の桃太郎像

岡山駅からの正面コース

岡山駅から岡山城までは、2キロくらいあるので、路面電車やレンタルサイクルを利用するのもいいでしょう。

駅前の「桃太郎大通り」をまっすぐ進むと、道の途中は、すっかり市街地になっていますが、外堀や中堀だった場所がわかるようにパネルが設置されています。

外堀跡
中堀跡

交差点に突き当たった場所は、内堀の中でした。右の方に向かうと、数少ない現存する城の建物の一つ、西の丸西手櫓が姿を現します(国の重要文化財に指定)。かつては、堀に向かってそびえていました。

突き当たりの交差点
西の丸西手櫓

次は、西の丸を回り込んでみましょう。西の丸の石垣が続きます。歩いている道も、堀だったのでしょう。やがて、石山門跡に着きます。建物は残念ながら戦災で燃えてしまいました。入口へは橋が堀を渡っていました。

西の丸石垣
石山門跡

更に進むと、今度は岡山城創建の地が見えてきます。石山の城(旧本丸)です。石垣は、池田氏の時代のもののようです。東側の入口から見ると、今は駐車場になっています。ちなみに、この辺から見える天守の姿は、スマートに見えて面白いです。

いよいよ本丸です。本丸へは、内堀にかかる橋(目安橋)を渡っていきます。渡った先の本丸入口は枡形(四角い防御空間)になっています。内下馬門(うちげばもん)跡です。

目安橋
内下馬門跡

本丸は、三段構成になっていて、高い方から順に、本段、中の段(表向)、下の段と呼ばれています。特に中の段は、小早川・池田時代に拡張されました。門跡から進んでいくと、中の段の隅にある大納戸櫓跡の石垣が見えます。小早川氏の時代に築かれたと言われています。最初に歩いている低い場所が下の段です。

下の段、中の段の石垣が見えます

本段の石垣も、中の段の入口にかけて改修されています。宇喜多時代の石垣を、小早川・池田時代にかけて継ぎ足したり、修理したりしました。中の段の入口、鉄門(くろかねもん)跡を登っていくと、本段への入口、不明門(あかずのもん、再建)前に着きます。

旭川沿いの搦手?コース

次のコースは、京橋から旭川沿いに城にアクセスします。京橋は、宇喜多秀家の時代に最初に架けられたそうです。

川沿いに展示されている江戸時代の京橋の橋脚

川沿いに東門跡、素軒屋敷櫓(そけんやしきやぐら)跡が現れます。こんなところにも門や櫓があったのです。続いて、二の丸伊木長門屋敷内櫓跡もあります。二の丸の重臣の屋敷内にも櫓があったようです。天守も見えてきました。

本丸に着いたら、石垣を見学しましょう(本段南東部の高石垣)。すごい迫力です。宇喜多秀家時代に築かれたもので、自然石を積み上げた野面積みの手法によります。高さが約15メートルあって、当時は屈指の高石垣でした。見ているうちに、安土城の石垣を思い出しました。やはり、安土城のやり方を引き継いでいるものがあるのでしょう。

本段南東部の高石垣

川沿いに戻って、天守の方に進むと、宇喜多時代と小早川時代の石垣の継ぎ目を見ることができます。後の小早川時代の方が、小さい石を使って積まれています。急いで作ったからなのでしょうか?池田氏の時代に作られた門(六十一雁木下門跡)の跡を見て進むと、天守台石垣に至ります。

オリジナルの天守が焼けたとき、外側の石垣の方に崩れてきたそうです。そのため、石垣も焼けてしまっています。まさに歴史の証人です。

天守の近くにある、本丸裏手の廊下門(再建)から入ると、このコースも本丸・中の段に到着です。

それでは、不明門から本段の中に入っていきましょう。本段はお殿様の住居なので、普段はこの門が閉ざされていて、こういう名前になったと言われています。本段の中には、オリジナルの天守の礎石が並んでいます。天守焼失後に現在地に移されました。

現在の外観復元天守の中は歴史博物館になっていますが、最近リニューアルされました。例えば、「城主の間」が再現されていたり、3大名家の「それぞれの関ヶ原」の展示があったりします。

天守5階には、金鯱が展示されています。実際に屋根に乗っているものも、同じ階から間近に見ることができます。最上階(6階)では、屋内からではありますが、周りの景色を楽しむことができます。天守1階には休憩コーナがあって、城の解説ビデオを視聴することができます。

その解説ビデオで殿様の一日を再現していたので、少しトレースしてみましょう。帰りは、天守の脇から廊下門の方に出てみます。お殿様が、本段の御殿から、政務を行った表書院に通ったルートだったからです。お殿様は、門の上の渡り廊下を渡ったのです。

天守から廊下門のところに出ました。

廊下門から、表書院に向かい、中の招雲閣で政務を行い、南座敷で書画に親しみました。現在では、地面の上に間取りが表現されています。そして家老と相談があるときには、茶室で行ってました。

奥が天守、左側が廊下門、手前が表書院のあった中の段

それから中の段で面白いのが、掘り出された宇喜多時代の石垣が見学できることです。中の段を広げるときに埋められたものです。元は、門の一部だったのでしょうか。

殿様気分で後楽園へ

後楽園に行く前に、現存する月見櫓もチェックしていきましょう。この櫓は池田時代に立てられているので、天守台の石垣や、天守の建物とは雰囲気が違います。石落としが、ばっちりこちらを狙っていて、となりの石垣には銃眼が並んでいます。内側から見たときの優雅な姿とは全然違います。守りのために漆喰で塗り固めたので、戦災を生き残れたという話もあります。現在は、国の重要文化財に指定されています。

それでは、後楽園に向かいましょう。

現在の鶴舎

これが、藩主の居間だった延養亭(えんようてい)で、戦災で焼失しましたが復元されています。

となりに、鶴鳴館(かくめいかん)という接待用の建物があったのですが、これも戦災で焼失し、戦後に岩国の吉川家のお屋敷(明治時代建築)を移築して、同名の建物として継続しています。

築山(唯心山)は、創建者・池田綱政の子、継政が作りました。ここからだと、芝生や池がよりきれいに見えますが、その中には田んぼ(井田、せいでん)もあります。それは後楽園(御後園)の当初の姿の名残りと言われています。

現存する建物の一つ、流店で休憩するのもいいでしょう。最後は、これも現存する廉池軒(れんちけん)の前にきました。池田綱政のお気に入りの場所だったそうです。貢献した家臣をここに招いたりもしていたそうです。

70.Okayama Castle Part1

Okayama Castle was still located in Okayama City which is the prefectural capital of Okayama Prefecture. Its main tower was nicknamed as “Ujo” which means “Crow Castle” because of its black colored walls. This article will explain its story from the beginning to its completion.

Location and History

Introduction

Okayama Castle was still located in Okayama City which is the prefectural capital of Okayama Prefecture. Its main tower was nicknamed as “Ujo” which means “Crow Castle” because of its black colored walls. Although the original main tower was unfortunately burned down by the Okayama Great Air Raid on the 29th of June in 1945, it was apparently fully restored in 1966. There is the Okayama Korakuen Garden across the river from the castle, which is called one of Japan’s three most beautiful gardens. Therefore, the area around is a very popular tourist spot. The area was created not for a short time but for a long time between three different lord families. They are the Ukita Clan which built the castle, the Kobayakawa Clan which modernized it, and finally the Ikeda Clan which completed it. As a result, the castle became the origin of the city. This article will explain its story from the beginning to its completion.

The current main tower of Okayama Castle

Was Naoie Ukita an Accomplished Villain?

Naoie Ukita became a great warlord around the current Okayama Prefecture in his life during the Sengoku Period. However, he wored so hard to achieve this that he has been labeled “an accomplished villain” or “One of the three great villains” in the period (the other two were Dosan Saito and Hisahide Matsunaga”). The bad reputation started from the first Edo Period. Hoan Oze, a writer at that time, described it in his “Hoan Taikoki” which is a popular biography of Hideyoshi Toyotomi. He wrote as followed:

“A person, who has a good talent, but uses it for his own benefit against justice, would eventually destroy himself.”

He mentioned Naoie in the example above. Hoan was devoted to Confucianism, therefore, he seemed to look back at the Sengoku Period to make a consequence theory. As a reality, most warlords were also something like Naoie which Hoan wrote, but as a result, most people during the peaceful Edo Period accepted Hoan’s theory. The three villain’s family’s power declined then because of financial reasons; therefore, they lost the ability to complain about it.

The theory was accelerated by the Bizen Gunki, a war chronicle which was written during the late Edo Period. This book is one of the few remaining records which say Naoie’s early days as followed:

“Naoie and his family were attacked by an enemy but managed to escape from their castle and wandered when he was only a little child. After he grew up, he served the Uragami Clan and avenged the enemy. He also got promoted because of his talent. However, he worked hard for this. For example, he even killed his relatives even they were his son-in-laws. He used any means necessary such as tricks, assassinations and the use of poison. He eventually defeated his master to become a great warlord.”

The book makes us believe that Noaie was really an accomplished villain. However, recent studies are confirming these descriptions one by one. So far, some of them are false (for example, one of the murders was not actually committed by Naoie). The work is incomplete and vague. If more evidence comes out in the future, Naoie might actually be seen as a hero rather than a villain. Even though many of the descriptions are confirmed, they may have been common ways for warlords to survive. In addition, the hierarchical system was very chaotic and unstable during the Sengoku Period. It was often revised and changed because of the power struggle that often plagued the Senoku Period, unlike the peaceful Edo Period.

Naoie’s last home was Okayama which was near the Seto Inland Sea to the south at that time. The location was good for land and water transportation. It was on the delta of estuary of Asahigawa River which flowed into the sea. The delta had three hills, one of which was called Ishiyama (which means stone mountain), where Naoie built the main enclosure of the castle. Another one was called Okayama, which was the origin of the castle and the current city’s name. The scale of the castle was still small. However, Naoie expected that the castle and town would eventually prosper.

After Naoie became a great warlord, his actions were recorded multiple times. However, the records say Naoie was worried about his last decision. In the late 1570’s, the Oda Clan and the Mori Clan battled each other over the Chugoku Region including Naoie’s territories. He was on the Mori’s side and fought against the Oda Clan. At first the Mori Clan was more superior than the Oda Clan which eventually changed. Naoie seemed to continue watching this trend while keeping a cool head. He finally decided to switch over from the Mori to the Oda in 1579 through the agency of Hideyoshi Hashiba who was a senior vassal of the Oda Clan. That meant Naoie would become the frontline against the Mori Clan. Severe battles continued for a while. Naoie unfortunately got sick and eventually died around January in 1582 (according to the lunar calendar). Hideyoshi wanted to expand his empire. He entered Okayama Castle in April and battled against the Mori Clan at Bicchu-Takamatsu Castle in May before the Honnnoji Incident happened in June, which resulted in him being the next ruler. As a result, Naoie’s decision was correct.

Hideie Ukita, a young nobleman of the Toyotomi Government, develops the Castle

Hideie Ukita followed his father, Naoie when he was only 11 years old but was supported by his relatives. The Ukita Clan joined the unification of Japan by Hideyoshi Toyotomi (who changed his name from Hashiba). Hideie was eventually promoted by Hideyoshi finally as a member of the council of the 5 elders. He was the youngest member in the council (at only 27 years old) while the others were all over 40. Historians speculate that there are 4 reasons for his early promotion.

The portrait of Hideie Ukita, owned by Okayama Castle (licensed under Public Domain via Wikimedia Commons)
  1. Hideyoshi felt an obligation for the contributions of the Ukita Clan
    The clan joined Hideyoshi’s troops during the most important period of his unification of Japan.
  1. The affection from Hideyoshi to Go-hime, Hideie’s wife
    Go-hime was a daughter of Toshiie Maeda, who was adopted to Hideyoshi when she was a baby. Hideyoshi loved her very much because he didn’t have children then. However, he finally got more children later on his life. Her husband was Hideie. When she suffered from a terrible sickness, Hideyoshi blamed it on the curse of the foxes. He ordered Fushimi Inari Shrine to pray for her recovery (the shrine uses foxes as envoys). He also declared that he would destroy the shrine and hunt foxes every year if she died. She fortunately recovered. Go-hime was the important connection between Hideyoshi and Hideie.
  1. The good relationship between Hideyoshi and Hideie himself
    There are no records that indicate Hideyoshi, who was a whimsical ruler, was ever angry at Hideie. Hideyoshi once announced that Hideie would be the ruler of Japan or Korea during the first stage of his invasion of Korea. (Hideyoshi himself wanted to rule China.) Hideie didn’t have his own military contributions but was often active fighting which might have been admired by Hideyoshi. He also spent huge amount of money and time for Noh plays, tea ceremonies, and falconries (using a falcon for hunting), which Hideyoshi also liked. In addition, you might think he was handsome person when you look at his portrait. However, the image above was drawn during the Showa Era using the author’s imagination.

4, Hideyoshi wanted to promote his relatives
When Hideyoshi got old, all of his male relatives were all gone excluding his only son, Hideyori. For example, the ex-successor, Hidetsugu was forced to kill himself by performing Harakiri. Hideyoshi’s brother, Hidenaga died because of illness. Hideie might have been considered one of his few relatives who would support Hideyori in the future.

Hideie was also a great lord who several territories with about 500,000 Koku of rice. Okayama Castle was renovated as his home. It was said that the construction was done between 1590 and 1597. The center of the castle was moved from the Ishiyama hill to the Okayama hill to the east. The new center (the main enclosure) was surrounded by high stone walls which was over 15m high. They were built piling up natural stones, which was called the Nozura-zumi method. Asahigawa River had been diverted into several flowing rivers around the castle but was converged as a natural moat in the north and east of it. Many other enclosures were also built in the southern and western parts of the castle, which were surrounded by artificial moats. The castle town was well developed. However, Hideie was so busy that he couldn’t live there for a long time. However, he sent his instructions on how to build the castle town to Japan from Korea where he was positioned during the invasion.

The remaining stone walls of Hideie’s period

The most interesting thing of the castle was its main tower as the symbol. It officially had 3 levels with 6 floors (however, some historians consider it 4 or 5 levels because of its complex roofs). It was over 20m high (about 35m in total including its stone wall base). The base was built along the natural terrain as the techniques were still primitive at that time. Therefore, the base became a scalene pentagon on a plane. As a result, the first floor became the same shape as the base. As you go higher, the shape turns into a square. Because of the complex floors, the first and second levels looks like multiple turrets and the top level like a lookout point was on them. This style is called “Boro-gata” (means the lookout type). The main tower of Okayama Castle is said to have followed the style of Nobunaga Oda’s Azuchi Castle and Hideyoshi’s Osaka Castle. The walls of the tower were painted black, which originated from the nickname of the castle, “Ujo” (means Crow Castle). In addition, the castle was decorated by rooftiles using gold leaves, which needed special permission from Hideyoshi to be used.

However, after Hideyoshi died in 1598, the situation changed dramatically. The authority of Hideie, which had been back upped by Hideyoshi, began to deteriorate. That caused an imbalance in power, which is often called Ukita Trouble. Some senior vassals, such as Ukita Sakyonosuke, and Hideie’s close vassals like Jirobe Nakamura fought against each other about who would rule their territories. Unfraternally, Hideie was not able to stabilize it. Eventually, many vassals left Hideie. For example, Ukita Sakyonosuke would become the lord of Tsuwano Castle. As a result, the power of Hideie would eventually disappear.

On the 15th of September in 1600 (according to the lunar calendar), the Battle of Sekigahara occurred, where Hideie joined the Western Allies but was unfortunately defeated. He escaped from the battlefield and hid in the mountain areas with his few retainers for a while. Then, he sailed to Satsuma Province to ask the Shimazu Clan which also joined the Western Allies for help. The clan still did not surrender to the Tokugawa Shogunate which was the former Eastern Allies. Hideie wanted to survive and get back to being a lord. After the clan and the shogunate made peace in 1603, Hideie presented himself at the shogunate the following year. The decision of the shogunate was to banish him to Hachijojima Island, nearly 300km away from Edo (the current Tokyo), forever. It was said Hideie never gave up on his comeback until his death when he was 84 years old in 1655. Hideie must have been stronger than his image of ” a young nobleman of the Toyotomi Government”.

Hideaki Kobayakawa, a Misfortunate Lord who Modernizes the Castle

After that, Hideaki Kobayakawa entered Okayama Castle as the lord of the Okayama Domain which earned him about 400,000 Koku of rice. This was his reward for helping Ieyasu win The Battle of Sekigaha. His actions gave him the reputaiton of a betrayer. He switched from the Western Allies to the Eastern Allies during the battle, being forced by the way of Toi-deppo (shot by Ieyasu Tokugawa). However recent studies suggest that Hideaki did not switch sides halfway through the battle but rather was supportive of the eastern allies from the very beginning. In spite of this, his bad reputation affected his relationship with the Okayama Domain. They said that Hideaki lived a luxurious life, doing bad things, and finally died a madman. As a matter of fact, he killed a senior vassal, which resulted in other senior vassals leaving him in fear of getting killed.

However, recent studies suggest that Hideaki’s death was caused by excessive alcohol drinking since his childhood. In addition, he left too many achievements for his short two years at Okayama before his death at only 21 years old. The purge to his senior vassals might have indicated his new government with his new close vassals. Some of Hideaki’s achievements include land survey, reorganization of temples, destroying unnecessary castles, and modernizing Okayama Castle (excessive castles could lead to rebellions which many lords wanted to minimize). The modernizing was done because the castle needed to adapt to new military methods after the Sekigahara battle.

Hideaki doubled the range of the castle (from 60 hectares to about 110 hectares). The outer third enclosure was built in the new western part of it. The outer moat also surrounded the enclosure, which was 2.5km long in total. It was said that the moat was built in only 20 days, which gives it its nickname “Hatsuka-bori” (which means 20 days moat). It was also said that it was fortified to prepare for the possible invasions from the Mori Clan. The clan was defeated during the Sekigahara battle and their territories were reduced by the shogunate, but Hideaki wanted to prepare for a possible revenge invasion from the west of Okayama Castle. In addition, Hideaki also extended the main enclosure and built new turrets and gates. We can see the stone walls of the enclosure, built by him, next to those of Hideie Ukita’s period. Some of the turret buildings were said to have been moved from castles which had been abandoned.

Hideaki died not having a successor. For this reason, the shogunate fired the Kobayakawa Clan. He was forced to mature at a young age, and like the wind he had an early demise. If he could have lived for few more years or have had his successor, his reputations would have been different from the current ones. He was really a misfortunate lord.

Ikeda Clan, the Pivot of Western Japan completes the Castle

Okayama Castle and the Okayama Domain was followed by Tadatsugu Ikeda when he was only 5 years old. He was a son of Terumasa Ikeda, the lord of Himeji Caste, whose wife was a daughter of Ieyasu Tokugawa. Therefore, Tadatsugu was a grandson of Ieyasu. This promotion may have been favoritism by Ieyasu. Tadatsugu was back upped by Toshitaka Ikeda (20 years old) who was another son of Terumasa, but his mother was different from Tadatsugu (Terumasa’s ex-wife). Tadatsugu died young just after he grew up, so his brother, Tadakatsu (14 years old but after his coming-of-age ceremony) followed him. Tadatsugu died when he was 31 years old and his successor (Mitsunaka) was only 3 years old back then. The shogunate decided to move Mitsunaka to Tottori Castle. Instead, Mitsumasa Ikeda, who was a son of Toshitaka, moved from Tottori to Okayama when he was 24 years old. Overall, the shogunate considered Okayama castle and the domain as an important spot in western Japan, where a young lord was not able to govern it properly.

Okayama Castle was finally completed by the Ikeda Clan. First, Toshitaka, who was the guardian of Tatatsugu, developed the inner second enclosure and the western enclosure. The remaining Nishite Turret was built at the western enclosure at the same time. Secondly, Tadakatsu extended the main enclosure to build the government office called “Omote-shoin”. The remaining Tsukimi Turret was also built there. The castle not only become a home for battles, but it also become an office for the government.

After Mitsumasa Ikeda became the lord, he improved the civil administration and cultural affairs in his domain. He learned Confucianism to lead the people in the domain. He also established the Okayama Domain School in 1669 for the Samurai-class people. Furthermore, he built the Shizutani School in 1670 for the lower-class people, which was said to be the earliest school for commoners in Japan. The constructions of the schools were instructed by his excellent close vassals like Nagatada Tsuda. On the other hand, the castle town of Okayama often suffered from natural disaster damages like floodings of Asahigawa River. This was because the river was artificially converged as a natural moat when the castle was renovated. As a result, the water of the river would often overflow to the town during harsh weather conditions. Mitsumasa ordered Nagatada to prepare preliminary measures for possible natural disasters. Nagatada decided to build spillways called “Hyakkenn-gawa” (which means 180m-wide river) at the upstream of Asahigawa River which came from the ideas of a Confucian, named Hanzan Kumazawa. The spillways usually worked as banks, but they changed to a river when the flow of Asahigawa River overflowed.

Mitsumasa’s successor, Tsunamasa liked culture and entertainment very much.
After the spillways were completed, the site across Asahigawa River from the castle became a wasteland. Tsunamasa launched the construction of his garden there, called Gokoen which is the current Okayama-Korakuen, one of the three greatest gardens of Japan. It was also instructed by Nagatada, who was like a superman! (a powerful retainer, rather than a powerful warrior) The garden was mostly consisted of fields, where farmers worked, as if it was a real countryside, by Mitsumasa’s interests. He commuted to his own garden by a boat from the castle occasionally. As time passed, the appearance of the garden was changed by his descendants. For example, most of the fields were turned into grass. Artificial hills and ponds were added on some points of the garden, which resulted in what we see today. The garden was also used for guests and opened to the public on somedays during the later Edo Period.

This article will describe how we visit the ruins of the encampments for the battle of Sekigahara (mainly of the Western Allies). We will finally go to the ruins of Matsuoyama Castle where Hideaki Kobayakawa was positioned.

Features

Introduction

This article will describe how we visit the ruins of the encampments for the battle of Sekigahara (mainly of the Western Allies). We will finally go to the ruins of Matsuoyama Castle where Hideaki Kobayakawa was positioned. In addition, as for the encampments of the Western Allies, we will visit them not only based on the defacto theory but also based on the new theories. Ogaki Castle may be a good starting point because the battle happened just after Mitsunari Ishida left the castle. You can see some exhibitions of him and the Sekigahara Battle in its restored main tower which has become a historical museum. Sekigahara Station is just few minutes from Ogaki Station.

Tour to Encampments of Western Allies based on Defacto Theory

It will be easy for visitors to visit the encampments based on the defacto theory because there are lots of information boards (also written in English). “Sekigahara Historical Landmark Tour” map, provided by the Sekigahara tourist association secretariat, will also help you. The following link is available in English.

So, let us first go to the encampment of Mitsunari Ishida on Sasaoyama Mountain, based on the defacto theory.

An example of the information boards

It may be better to go towards the Battle Site Memorial before reaching the mountain because you can find it easily. You can see the mountain where the flag of Mitsunari’s encampment stands.

If you reach the foot of the mountain, you will eventually see that it was the encampment of Shima Sakon who was Mitsunari’s senior vassal. In fact, there is no evidence which proves that the mountain was certainly their encampments. The current historical sites were designated by the officials during the Meiji Era, probably based on the local traditions of the Edo Period. However, the top of the mountain looks suitable for the stronghold. You can see a panoramic view from the top, including Nangusan Mountain on the left, where Hiroie Kikkawa was positioned, and Matsuoyama Mountain on the right, where Hideaki was positioned. If Mitsunari would have been on the top, he would have been able to see any suspicious actions by the lord.

Our next target will be the grave site of Yoshitsugu Otani, after passing the encampments of other lords of the Western Allies, such as Yoshihiro Shimazu, Yukinaga Konishi, and Hideie Ukita. You need to walk for few kilometers to reach the target. However, some soldiers who joined the battle testified that the lords were positioned together in the range of only few hundreds of meters. This is another mystery that his often debated by historians and experts.

You will eventually enter the Yamanaka area (which directly means “mountain area”), not like the Sekigahara field. There are actually some ruins of encampments, made by soil, which Yoshitsugu might have built. His grave is in the area, which is said that his retainer originally buried his head there. Takatora Todo, who had been his enemy, heard about it and developed the grave as we can see now. There are always offerings (such as flowers) in front of the grave, from his fans. This is probably because of his episodes in the battle. Yoshitsugu joined the Western Allies because of his friendship with Mitsunari but was defeated by the betrayal of Hideaki (according to the defacto theory).

Tour to the Encampments of the Western Allies based on New Theories

Let us next go to the encampment of Yoshitsugu Otani from his grave nearby.
His encampment has been designated based on the defacto theory while a new theory says it was, in fact, that of the Shimazu troops. By the way, there is the view spot of Matsuoyama Mountain near the encampment as well. You can see the flag of Hideaki’s encampment from that spot. I think the view is one of the reasons why Yoshitsugu’s encampment was designated nearby in the defacto theory. The theory says Yoshitsugu was positioned in order to better monitor the betrayal of Hideaki. On the other hand, in the new theory, Yoshitsugu was actually in the Sekigahara field, so another lord was expected to use the encampment instead of him.

We will next go to the encampment of Mitsunari Ishida, based on the new theory, after climbing down the mountain area. If you walk on the Old Nakasendo Road, you will eventually see a hill up ahead, which is the encampment, called “Jigai-ga-oka”. The hill is also a historical site of Jinshin War during the Ancient Time, called “Jigai-mine-no-sanbon-sugi” which means “The three cedars on Suicide Hill”. A tradition says as followed:
Prince Otomo was defeated by Prince Oama during the war and killed himself in another place. People around the hill, who loved him, got his head and buried in the hill. The three cedars are said to be the mark, which you can visit and see.

The three cedars on Suicide Hill, The two remaining cedar trees are not accessible however, because they have a chain fence around them

There is one more spot regarding both the Sekigahara Battle and the Jinshin War, after going on the road over Fujikogawa River. You can find Fuwanoseki Museum, which are the ruins of Fuwanoseki (which means Fuwa Gateway). The new theory says this spot was the encampment of Yoshitsugu Otani. In the Jinshin War, the gateway was the border between the forces of Otomo (the west) and Oama (the east). In the Sekigahara Battle, Sekigahara (which directly means “gateway field”) was that of the Western and Eastern Allies.

We will get closer to Matsuoyama Mountain. There are lots of flags of the Kobayakawa Clan at its entrance. It has a nice atmosphere.

Going to Matsuoyama Mountain

Matsuoyama Mountain is 293m above sea level and about 200m above the foot of the mountain. If you drive your car, you can park it at the foot. The trail to the top is part of Tokai Natural Trail, which has been well developed. The number of Hideaki’s troops were said to be about 8,000 to 15,000. They were probably stationed from the foot all the way to the top. If the Toi-deppo story is true, the soldiers at the foot would have been able to hear it.

The starting point of the trail, Notice the basket of sticks which is free for visitors to use.  Make sure you return it to the original basket after using it
The trail at the foot

Matsuoyama Castle is often called the encampment of Hideaki Kobayakawa, in fact, it was a full-scale castle. It had the main enclosure on the top and several other enclosures on its ridges. They were surrounded by earthen walls one by one and were divided by dry moats from each other. It also had ditches on the ridges and vertical moats on the slopes in order to prevent enemies from invading it. The castle was mostly fortified by the Western Allies just before the Sekigahara Battle. It was done using natural terrain and construction with soil.

& Folklore Museum

The trail looks like a well-developed forest road before turning into a fork. There is a sign which says 850m to the top. As you get close to the top, the trail goes beside a ridge which was the eastern enclosure of the castle. If you were an enemy back then, you would have been attacked by the defenders above.

Turn right, at the flag, Notice the drain on the road.  When it rains, the water flows down the mountain, and goes to the drains

You will eventually see several flags standing on the main enclosure of the top above. One of them is that of Hideaki Kobayakawa’s encampment, which you saw from the view spot of Matsuoyama Mountain. The view from the top is so nice that you will be encouraged to stop and stare for a while. It would have been the view of Kobayakawa according to the defacto theory.

The top will be soon

Is it a Castle or is it an Encampment?

Let us check out if Matsuoyama Castle is worth for a full-scale castle at the site. In fact, the opposite side of the trail we climbed looks more fortified, according to the pamphlet of Matsuoyama Castle. (unfortunately, the pamphlet is only available in Japanese)
We will enter the castle from the side.

The layout of the castle (from the pamphlet of Matsuoyama Castle), we first came from above

The path of the entrance gets narrower by being cut by the ditches on both sides. You will next pass an enclosure like a position, which is called the enclosure like Umadashi (the position which sticks out from the gate).

The path gets narrower again and wind towards the main enclosure. The entrance of the main enclosure is a square, surrounded by earthen walls, which is generally called Masugata. The route you walked on right now may be the front of the castle, where Hideaki might have also been at.

The path becomes narrow again
The path goes close to the main enclosure, Notice the wooden steps that were added later on by the town
The Masugata system at the entrance of the enclosure

You can also walk down to the dry moats surrounding the main enclosure, from the front of the Masugata system. You will see the vertical cliffs on the slopes of the enclosure, which were artificially cut for defense, on the way to the moats. The bottom of the moats looks spacious tough it is covered with trees and grass now. Historians speculate that it was used as passages or stations for soldiers. The moats also have earthen walls like normal enclosures have.

Going down to the dry moats
The vertical cliffs, Notice the narrow road partially covered in plants.  On the right, is the artificially cut soil, in order ot make the slope steeper for the enemies
The bottom of the moat
The earthen walls on the moat, Notice the sign in Japanese saying “altered earthen walls”

Finally, we will climb another enclosure on a hill, the opposite of the main enclosure. The top of the enclosure is leveled, probably in order to accommodate soldiers in the past. Overall, Matsuoyama Castle must have been a large basement for the Sekigahara Battle. I have confirmed that it was not only a simple encampment but also a full-scale castle.

My Impression

After visiting the Sekigahara area, I think it still has a mysterious vibe and can accept adventurous spirits with many theories. In addition, I also learned that the area has a long history including the gateway and battle between eastern and western Japan since the ancient time. In fact, the battle between them still continues today in the category of noodles. You can buy two types of instant noodles for eastern and western Japan there at the souvenir shop. Gifu Sekigahara Battlefield Memorial Museum is a very popular spot for visitors where you can learn about the battle and buy other souvenirs. You can also get Goshuin stamps (you can stamp a piece of paper to commemorate your experience) of the encampments you visited there; However, you will need to show the pictures to the counter staff as evidence.

That’s all. Thank you.
