Otaki Town is promoting the castle with Tadakatsu Honda.
Later History
After the Meiji Restoration, Otaki Castle was abandoned and all the buildings of the castle were demolished. The land of the castle was turned into fields, with a school and a residential area. The Imitation Main Tower was built in 1975 after the excavation in 1973. Otaki Town has been promoting this castle as being built by the famous general, Tadakatsu Honda.
My Impression
The Main Tower of Otaki Castle is temporarily closed (as of Oct22) as it needs repairs such as earthquake proofing. Otaki Town will operate it following Chiba Prefecture after the repairs. Castles that include Main Towers are indispensable to local cities or towns because they serve as symbol and facilities for tourism. I also recommend seeing the castle town street near Otaki Station, where some old merchant houses remain.
How to get There
I recommend using a car when you visit the castle. It is about a 30-minute drive away from Ichihara-Maizuru IC on the Ken-odo Expressway. You can park at the parking lot located under the Main Enclosure. If you want to use public transportation, it takes about 15 minutes on foot from Otaki Station. To get to Otaki Station from Tokyo: Take the Wakashio limited express and get off at Ohara Station and transfer to the Isumi Railway.
The castle started and ended with the Asakura Clan.
Location and History
Integration of Castle and Castle Town
Ichijodani Castle was located in Echizen Province (now Fukui Prefecture) which the Asakura Clan governed during the Sengoku Period. People usually consider this castle as a fortified city the Asakura Clan built. The city was integrated with a castle and castle town parts. Because of that, people at that time called the castle, just “Ichijodani”. People in the present time call it the Ichijodani Aasakura Clan Ruins.
The location of the castle
The Asakura Clan originally served the Shiba Clan, the family of the governor of Echizen Provence. Takakage Asakura was distinguished in the Onin War in Kyoto in the late 15th Century to support the Ashikaga Shogunate. As a result, the Shogunate assigned him the governor of Echizen Provence instead of the Shiba Clan. After that, the Asakura Clan governed the province over five generations for about 100 years. The clan chose a long narrow valley called Ichijodani as their home base, not the flat area called Fuchu which the Shiba Clan lived. The reason for the Aasakura Clan’s choice is thought that the clan had to continue fighting with the Shiba Clan and others like the Ikkoshu Sect.
The relief map around the castle
The valley was about 3km long from the north to the south, and about 500m wide. It was protected by several mountain castles on the mountains in the eastern and western side of the valley. “Ichijo-dani Castle” was one such castle but provided a limited amount of protection. Both edges of the valley also had fortress entrances built using earthen walls and water moats called the Inbound Fortress Entrance and Outbound Fortress Entrance. The area between the entrances, where Ichijo-dani River flowed, was called the Inside of the Entrances. The castle town was built along the narrow area, including the Asakura Clan Hall, the warriors’ houses, the merchants and craftsmen area, and temples.
One of Largest City in Sengoku Period
Ichijodani greatly prospered. Echizen Province was basically wealthy and the Asakura Clan earned lots of profits from trading by ships. The clan also united with their relatives and retainers to prevent enemies, like the Ikkoshu Sect, from invading their territory. These made the people in Ichijodani rich. The hall of the clan was very similar to that of the shogun’s deputy in Kyoto and had a gorgeous Japanese garden. The clan accommodated many nobles, high priests, and intellectuals from Kyoto, which was devastated after the Onin War. Warriors played Japanese chess inside their houses and priests enjoyed tea ceremonies. Trading and production were actively done in the town. The population of Ichijo-dani was said to reach about 10,000. The city became one of the largest cities in Japan, sometimes called a Little Kyoto.
Destroyed by Nobunaga Oda
In 1567, Yoshiaki Ashikaga, who would be the last shogun of the Ashikaga Shogunate, visited Yoshikage Asakura, the last lord of the clan, in Ichijodani. Yoshiaki asked Yoshikage to take Yoshiaki to Kyoto and defeat his enemies. Yoshikage rejected it, so Yoshiaki left Ichijodani and visited Nobunaga Oda in Owari Province (now part of Aichi Pref.). Nobunaga went to Kyoto with Yoshiaki who became the shogun in 1568. They ordered Yoshikage to go to Kyoto and serve them. Yoshikage rejected it again and finally became an enemy of the shogun in 1570. Nobunaga and Yoshikage fought against each other for three years. The unity of the Asakura Clan collapsed after the long battle. Yoshikage had to escape from Ichijo-dani and was defeated in the end. Nobunaga’s soldiers attacked Ichijodani without its master. The city burned for three days and ended its history in 1573. The castle was destroyed.
Today, Echizen-Ohno Castle is part of Kameyama Park on the mountain. There are four trails to the top of the mountain. Only one of the four routes called Hyakken-zaka is the original one which is zigzagged and steep.
The map around the castle
If you want to walk on a gentle slope, you can use other routes such as the Southern Route. The walk takes about 15 to 20 minutes. If you choose the Southern Route and climb up stone steps after the walk, you will arrive at the Main Enclosure on the top.
Old Stone Walls and Rebuilt Main Tower
The enclosure is surrounded entirely by the old stone walls which Nagachika Kanamori originally built. These stone walls were piled up using natural stones in an old way called Nozura-zumi. They look wild but were built wisely. Part of them seemed to have been re-piled when the castle buildings were rebuilt in the present time.
What you see on the stone walls is the rebuilt Tenshu which was constructed in 1968. It doesn’t resemble the original Tenshu of Echizen-Ohno Castle which looked like combined halls. It looks like a typical Main Tower which people in Japan usually imagine as Tenshu. The reason why such a Tenshu was built was probably because people in this area wanted it. The Tenshu building is actually a modern building which is also used as a historical museum and an observation platform. You can learn more about the castle inside.
From the top floor, you can enjoy a great view of Ohno city area including the old castle town and Inuyama Mountain where the old castle before Echizen-Ohno Castle was built.
Attractions at Foot of Mountain
You can also visit other attractions of the castle at the foot of the mountain. There is an educational complex in the Second Enclosure now called Meirin. The facilities include a primary school and a community center. The short part of the water moat remains in front of the facility.
There is the restored house of the Uchiyama Clan, a senior vassal family of the Ohno Domain. There is also the remaining warrior’s house of the Tamura Clan around.
Attractive Castle Town
If you have time, I recommend walking around the old castle town. For example, the morning market is held every day excluding midwinter at the Shichiken Street in the merchant area. A famous spring spot called Oshouzu is near the temple area. It was used by the lord of the castle. There are a lot of springs in this town, which have been used for domestic water since the town was developed.
You can also see zigzagged streets at several points, which were made to prevent enemies from attacking the castle easily.
