Visitors praise Oko Castle Ruins for its well-preserved historical remnants, including foundation stones and impressive earthworks, offering a glimpse into Japan's Sengoku period.

"30minute bus ride from Kochi station. Nicely preserved castle ruins on an easy to climb hill."

Mainbridge Hashimoto

"Best view of Nankoku city from this place"

"This is the remains of Oko Castle, one of the 100 most famous castles in Japan. I went by car, but I was able to park at the Kochi Prefectural Museum of History and Folklore.
You can get a stamp at the museum, so you can also get some materials.
The castle as a whole seems to be quite large. I decided to climb towards the inner citadel (main citadel).
The museum is already located about halfway up, so I arrived in about 10 minutes. It was nice to see the earthworks and moats along the way.
The foundation stones are preserved at the inner citadel, giving a glimpse of the old buildings.
The view was also great, and I could see quite far into the distance."
