138.Echizen-Ohno Castle Part1

Nagachika Kanamori built the unique Tenshu and the castle town.

Location and History

Nagachika Kanamori, retainer of Nobunaga Oda, builds Castle

Echizen-Ohno Caste was located in Ohno Basin in the eastern part of Echizen Province, what is now Fukui Prefecture. The Asakura Clan governed the province until 1573 during the Sengoku Period when the clan was defeated by Nobunaga Oda. The Ikkoshu Sect once took over the province, but Nobunaga defeated them again in 1575. Nobunaga gave the area around Ohno Basin to his retainer, Nagachika Kanamori, who was distinguished in the battle. This area connected the western, seaside part of the province and Hida Province inland. It was an important area for warlords to govern Echizen Province.

Nagachika first lived in Inuyama Castle, a mountain castle beside the basin, which the Asakura Clan used. However, Nagachika decided to build a new castle and its castle town in the basin in 1576 to make his governance stable. He seemed to build both the castle and castle town using advanced methods. These methods were similar to ones used for the historical home bases Komakiyama and Gifu Castles, which were built by his mater, Nobunaga Oda. For example, the new castle called Echizen-Ohno Castle was built with stone walls and the Tenshu building on a hill called Kame-yama in the basin.

Unique Tenshu and Advanced Castle Town

Tenshu basically means the Main Tower in the center of a castle. However, the Tenshu of Echizen-Ohono Castle did not look like a Main Tower. Instead, it looked like three combined halls. This was because the construction of Echizen-Ohno Castle started before the completion of Azuchi Castle in 1579, Nobunaga’s last home base. Azuchi Castle had the first Tenshu building which looked like the Main Tower in Japan. Before that, Tenshu had just meant the center building of a castle. Echizen-Ohno Castle was completed in 1580 and its Tenshu building remained for a long time. However, the Tenshu was unfortunately burned down in 1795 and not restored. If the castle survived, it would be considered quite a unique part of Japanese History and heritage.

Nagachika created the castle town in an advanced way as well. The town was divided orderly to accommodate warriors, merchants, craftsmen, and temples separately. Such a way to develop castle towns is commonly seen in those in the next century. His master, Nobunaga Oda created the castle town of Komakiyama from the ground up. Nagachika might have followed his master’s method. However, the Komakiyama castle town was abolished by Nobunaga. The people were forced to move with Nobunaga to his next home base, Gifu Castle. By contrast, the Echizen-Ohno castle town remains today as the city area of Ohno City. Nagachika also created Takayama Castle and Takayama town after he was transferred to Hida Province in 1586. The traditional town has now become a world-class tourist destination.

Doi Clan governs from Second Enclosure Main Hall

After Nagachika, the lord of the castle changed several times. The Doi Clan governed the castle and the area as the Ohno Domain throughout the Edo Period since 1682. In peaceful times, the lord of the castle lived in the Main Hall in the Second Enclosure at the foot of the mountain. The enclosure was surrounded by a long water moat called Hyakken-bori. The lords rarely used the facilities including the Tenshu on the mountain, called the Main Enclosure, because of the inconvenience of the location. In addition, it would be difficult for officials to govern. That may be why the Tenshu wasn’t restored after the fire.

180.Okoh Castle Part1

The castle’s long history and the Chosogabe Clan

Location and History

Feature of Tosa Province

Okoh Castle was located what is now Nankoku City, Kochi Prefecture. The prefecture is one of the four prefectures in Shikoku Island, but separated by Shikoku Mountains from the other three northern prefectures. When the prefecture was called Tosa Province in the past, it was not easy to visit there. That’s why the province was sometimes used for one of the places for exile or escape. However, it has been easy to live for local people with a warm climate and abundant food.

Chosogabe Clan settled in Tosa and built Castle

Okoh Castle had been owned by the Chosogabe Clan during all its life. The clan has a very long history and it was said that their founder was a branch of the Hata Clan that came from Korea to Japan in the Ancient Times with advanced technologies such as civil engineering and silk industry. The Hata Clan spread them and moved from central Japan (now Kinki Region) to many local areas of Japan including what is now Nagano Prefecture where the founder of the Chosogabe Clan lived. The founder called Yoshitoshi Hata fought at Kyoto in the 12th Century, but was defeated, so he escaped from his enemies to Tosa Province. He finally settled near the provincial capital in the fertile Kacho Plain and changed his family name to Chosogabe by combining local land names. Okoh Castle was thought to be built on a mountain beside the plain at the same time.

One of Chosogabe’s strengths was to have connections to central Japan such as serving the Hosokawa Clan, a senior vassal of the Ashikaga Shogunate and inviting the Ichijo Clan, a high class noble to Tosa Province as the provincial governor. As a result, the Chosogabe Clan became one of the seven ruling clans in Tosa in the first 16th Century. However, the others of the seven ruling clans including the Motoyama Clan were against the Chosogabe Clan, then they attacked and burned Okoh Castle in 1508. The trace of the fire was found in the ruins of the castle. The Chosogabe Clan was once defeated.

Motochika Chosogabe ruled Shikoku based in this Castle

The next lord of the clan, Kunichika Chosogabe came back to Okoh Castle in 1518 with the support from the Ichijo Clan. He got his power by organizing a soldier group called Ichiryo-Gusoku who were usually farmers, but also soldiers with a Set of Armour in emergency. After that, he took revenge on his enemies by taking them as relatives or battles with the Ichiryo-Gusoku group. Kunichika’s son, Motochika Chosogabe was succeeded in governing the whole Tosa Province in 1575. Okoh Castle had been the home base of the clan. It was a typical mountain castle with many tiers covering the mountain. However, it had some unique features coming from the Chosogabe Clan. It was thought that some turrets were built on stone foundations, using roof tiles made by craftsmen from Izumi Province (now part of Osaka Prefecture). Stones were piled inside the earthen walls of the Third Tier. Such structures were still rare at that time in the whole cuntory and were done by Motochika’s connection to central Japan.

Abandoned after Unification of Japan by Hideyoshi Toyotomi

Motochika finally achieved the unification of Shikoku Island in 1585. However, the ruler, Hideyoshi Toyotomi was processing his unification of Japan at the same time. Hedeyoshi sent over 100,000 of modernized troops to Shikoku Island in the same year while Motochika had about 40,000 soldiers including farmers. Motochika had no other option but to surrender and was allowed to govern just Tosa Provence by Hideyoshi. He also moved his home base from Okoh Castle to Otaka-sakayama Castle (now Kochi Castle) in 1588 and finally Urado Castle beside Urado Bay in 1591. it was said that this transfer was instructed by Hideyoshi to prepare his Invasion of Korea in 1592. Okoh Castle was abandoned then.

76.Tokushima Castle Part1

Many evolution of Tokushima Castle

Location and History

Iemasa Hachisuka built Castle

Tokushima Castle was located in what is the modern day Tokushima City. The prefectural capital of Tokushima Prefecture is Tokushima City. The old name for Tokushima Prefecture was called Awa Province, where the Chosokabe Clan and the ruler, Hideyoshi Toyotomi battled in the late 16th Century during the Sengoku Period. Hideyoshi finally won and he gave the province to his senior vassal, Iemasa Hachisuka in 1585. Iemasa first lived in one of the major mountain castles, called Ichinomiya Castle, but he soon moved to another place in 1586, building a new castle named Tokushima Castle.

building network of sea transportation

Tokushima Castle was built on Inoyama Mountain which was 62m high on a sandbank called Inotsu. The sandbank was among the delta of Yoshino-gawa River, the largest river in Shikoku Island. The place where the castle was built was not spacious for the lord of the province. It was said that Hideyoshi suggested that the castle should be built at that place. So why did he instruct Iemasa to build the castle at such a place? Historians speculate that Hideyoshi tried to build the network of sea transportation with his home base, Osaka Castle. Tokushima was renamed by Inotsu and had a location which was capable of controling the sea lanes such as Kii Channel. The area was the entrance to Osaka Bay in which Osaka Castle was facing. The network consisted of both navy and merchant fleets. Another possible reason was that The Hachisuka Clan still had to send their retainers to branch castles called the Awa Nine Castles against the resistances of Chosokabe. That meant Hachisuka’s home base didn’t need a large space.

The positional relation between Tokushima Castle and Osaka Castle

Center of Castle was once on Mountain

Inoyama was a dogleg mountain which extended from the east to the west. The Main Enclosure was on the highest, the largest and rounded part of the mountain, which was thought to have the first Main Tower and the first Main Hall for the lord. However, the Main Tower was scraped about 30 years after its foundation for some unknown reasons and rebuilt in the Eastern Second Enclosure of the lower eastern part of the mountain. This was a very rare case because most castles had their Main Tower at the highest point of the mountain. There’s only one other castle that had a similar case, which was Mito Castle. However, its reason was more obvious. Its main reason was that it was small and inconvenient. The western part of the mountain also had the Western Second Enclosure and the Western Third Enclosure that protected the Main Enclosure. These enclosures on the mountain got surrounded by stone walls one by one. On the other hand, the plain area on the sandbank in the south of the mountain was not fully developed. Experts speculate that there were probably two main halls instead of one primary hall on the mountain. This secondary hall on the plain area was used as the home of the lord and its warriors. Tokushima Castle was specifically designed for battles that took place during the first generation of its existence.

The enclosures were built on Inoyama Mountain, the Main Tower was built on the lower eastern part. not on the Main Enclosure (*Part of the illustration of Tokushima Castle in Awa Province*)

Center of Castle moves to plain area

After the Tokugawa Shogunate defeated the Toyotomi Clan in 1615, the governance of the shogunate finally became stable. The Hachisuka Clan was also able to spread their territory by adding the Awaji Province through supporting the shogunate. Due to the long period of peace, The nine branch castles were eventually abandoned. As a result, the retainers gathered in Tokushima Castle which needed to be reconstructed. The large scale of the Main Hall for the lord was rebuilt on the plain area and became the center of the castle. It was also surrounded by stone walls with several turrets, and fences called Byobu-bei along with the Inner Moat and the Terashima-gawa River. The southern side of it had the Kuro-mon Gate as its main gate with the three-story turret called Taiko-yagura next to it, which looked like the main tower. In addition, there was also the Miki Enclosure in the south of the Main Hall with the front gate called Washi-no-mon. Many of the rivers around the castle were also reclaimed and turned into the warriors’ residences and the castle town. The Hachisuka Clan lived in the castle until the end of the Edo Period.
