82.Ozu Castle Part1

Many clans developed Ozu Castle and the area around.

Location and History

Utsunomiya Clan first builds Castle

Ozu Castle was located in the southern part of Iyo Province on Shikoku Island, which is now Ozu City in Ehime Prefecture. The castle was first built on a hill called Jizogadake by the Utsunomiya Clan in the 14th Century. This location was near the intersection of Ozu-Uwajima Road and Hijikawa River, an important point for transportation. The Utsunomiya Clan eventually became one of the local warlords in the province during the Sengoku Period in the late 15th to the 16th Century.

Takatora Todo modernizes Castle

After Hideyoshi Toyotomi achieved his unification of Japan, Takatora Todo, who worked under Hideyoshi owned Ozu Castle in 1595. He was based in Uwajima Castle, but he modernized both Ozu and Uwajima Castles. The details of improved Ozu Castle by Takatora are uncertain, because the ruins of it are under the current Ozu Castle. However, it is thought that the basic structure of the castle was completed by him. The Main Enclosure was on the hill beside Hijikawa River flowing from the east to the north of the castle. The Second Enclosure was below the hill on the opposite side of the river. Both enclosures were surrounded by the Inner Mort in the south and west. The Third Enclosure and the Outer Moat were also outside of them. The water of the moats was from the river, so the castle is also called a River Castle.

Yasuharu Wakizaka builds Main Tower?

In 1609, Yasuharu Wakizaka, was transferred from Sumoto Castle to Ozu Castle as the founder of the Ozu Domain. It is said that he built the four leveled Main Tower in the Main Enclosure. Some historians also speculate that he might have moved the Main Tower of Sumoto Castle to Ozu. This is because the sizes of the stone wall bases for both castles are almost the same, according to the recent research. The two two-story turrets called Daidokoro-Yagura and Koran-Yagura were built at both sides of the Main Tower, connected by the Passage Turrets. Many other turrets were also built in the important positions of each enclosure.

Kato Clan maintains Castle

In 1617, the Kato Clan was transferred from Yonago Castle to Ozu Castle, which governed the castle and the Ozu Domain over 13 generations until the end of the Edo Period. The domain didn’t have a large territory (60 thousand rice of koku) which meant they were not rich. However, it promoted industries such as Tobe pottery, Japanese papers and Japan wax. It also founded the domain school called Meirinkan to educate warriors. At the end of the Edo Period, one of the warriors, Ayasaburo Takeda learned the Western military science after graduation. He lastly built the first Western style castle called Goryokaku in Hakodate, Hokkaido Island, he also worked as the instructor of the Tokugawa Shogunate.

As for Ozu Castle, the Second Enclosure became the center of the castle in the peaceful time, having the Main Hall, warehouses surrounded by the Main Gate and some turrets.

80.Yuzuki Castle Part2

The beauty between the Inner and Outer Moats of Yuzuki Castle was restored.

Features

Entrance of Castle Ruins

Today, the ruins of Yuzuki Castle have been developed as the Dogo Park. The western and southern parts of it are the restored area. The western entrance, which was originally used as the back gate, looks like the front gate now. If you go across the earthen bridge over to the Outer Moat to enter the inside of the earthen walls, you may feel like you are inside a medieval castle. You can first visit the Yuzuki Castle Museum near the entrance to learn more about the history of the Kono Clan and how the area was first developed.

Restored Warrior’s House

Next to the museum in the western part, which is a middle-class warrior’s house, including the gate and mud walls in front of it, was restored. If you enter the house, you will see its interior was also restored because the layout was discovered by the excavation team. There are five mannequins representing people who once lived in the castle enjoying a poetry party in the meeting room, while another mannequin is preparing a meal and tea in the kitchen.

You can visit the other restored warrior’s house with the exhibition room inside. The reason for this is the original layout of it is not clear to see even though the excavation was already done.

High-class Warriors’ Residential Area

The southern part was originally used as a Japanese garden as well as the residential areas for the high-class warriors. You can now see the diagram on the lawn of how the residential were back then. The wild rocks of the hill still face where the garden was used to be, so the rocks might have been used as a natural scenery for the garden. I recommend seeing the Inner Moat with the earthen walls nearby.

Unique Earthen Wall Exhibition Room

As for the earthen walls beside the Outer Moat, there is the exhibition room showing the earthen walls, inside them. You can see the original cutout model of the walls confirming how the excavation team penetrated, and explanation for them. This model was taken when the excavation was done and used to visualize how other earthen walls would have been restored. It is very interesting and easy to understand how great the construction was.

80.Yuzuki Castle Part1

The center of Iyo Province in the Middle Ages

Location and History

Great find of Matsuyama City

Matsuyama City is one of the most popular tourist spots in Japan, which is also known for attractions such as the Dogo Hot Spring and Matsuyama Castle. However, you should check out another one as well, called Yuzuki Castle. The Dogo Hot Spring has been said to be the oldest hot spring in Japan, so some ancient imperial family members probably including Prince Shotoku once visited there and stayed for a while. The hill, where Yuzuki Castle would be built later, was near the hot spring and had the Isaniwa Shrine at the top. That means the area around the hill had been considered a holy place by the people in Iyo Province which is now modern day Ehime Prefecture.

Official Residence of Governor, Kono Clan

The Kono Clan was one of the local clans in Iyo Province. When the Mongol Invasion happened in 1281, Michiari Kono, the lord of the clan, was very active in the battle against the Mongol troops, who was also drawn in the picture scrolls of the Mongol invasion attempts against Japan, which was produced by Suenaga Takezaki. In the first 14th Century, the Kono Clan managed to take over the province, therefore, they built Yuzuki Castle on the hill after relocating the shrine to another place next to the hill. The clan finally became the ruling clan of the province, living in the castle as the official residence of the governor. The holy spot probably also provided the clan more authority.

However, the governance of Iyo Province by the Kono Clan was not very stable. This was because other clans such as the Hosokawa and Ouchi Clans invaded the province. The Kono Clan itself sometimes had internal troubles as well. In 1535 during the Sengoku Period, Michinao Kono, the lord of the clan at that time, built an Outer Moat using earthen walls inside, to make his castle much stronger defensively. The castle originally had an Inner Moat with other earthen walls outside, so by having the second outer moat, it doubled the moats.

You can see the doubled moats of Yuzuki Castle in the miniature model of the ruins, exhibited by the Yuzuki Castle Museum

It is still uncertain what the center of the castle on the hill was used for, but the lord of the castle might have lived there. The area between the Inner and Outer moats was shared by the warriors for living and divided by the mud walls for each resident. The southern part was used as the residences for the high-class warriors. Each portion for them was large and a Japanese garden was built next to that part. On the other hand, the western part was used as the residences for the middle-class warriors. Each portion was much smaller than that of high-class residences, but one of the residences had a meeting room where people could enjoy parties for poetry which were very popular back then. In addition, the castle had at least two gates, one on the eastern gate which was the front and another one on the western side which was the back.

Castle is abandoned after Kono Clan declines

Despite the renovation of the castle, the Kono Clan struggled to maintain it. According to the excavation, the castle was burned down after the renovation. The clan managed to rebuild the castle and tried to survive by working closely with the Kurushima Clan as well as with the Murakami navy forces. Despite the invasion by the Chosogabe Clan from Tosa Province, which was the south of Iyo, along with the unification of Japan by Hideyoshi Toyotomi, the Kono Clan had to ask the Mori Clan in the Aki Province, which was the north of Iyo, for help. In 1585, Ushifukumaru Kono, the last lord of the clan, handed the castle over to Takakage Kobayakawa, who was a relative of the Mori Clan. In 1588 when Masanori Fukushima, following Takakage, moved from Yuzuki Castle to another castle. the castle was eventually abandoned.
