Yamanaka Castle had been abandoned for a long time since the battle in 1590. In 1930, a descendant of Naosue Hitotsuyanagi made a plan for the historic site. As a result, the ruins were designated as a National Historic Site in 1934. In addition, Mishima City excavated the ruins and developed them as a historical park between 1972 and 1993. That’s why we can now enjoy visiting the park, learning history, and relaxing.
My Impression
The development for the Yamanaka-jo Castle Park was completed in 1993, nearly 30 years ago. I think that this is one of the very early cases for historical parks in Japan. This can also be a good model for the historical parks for other castles which are now being developed. Basically, the western slope of the Hakone Barrier has been a perfect spot for viewing Mt. Fuji. If the weather is fine, you can get both views of the mountain and the castle ruins there.
How to get There
If you want to visit there by car: From the east, it takes about 30 minutes from Hakoneguchi IC on Seisho Bypass. From the west, it takes about 40 minutes from Numazu IC on Tomei Expressway. The park offers a parking lot at the entrance. By bus, get on the Tokai Bus bound for Moto-Hakone-Ko from the south entrance of Mishima Station, and get off at the Yamanaka-Jo-Ato bus stop. To get to the Mishima Station from Tokyo: Take the Tokaido Shinkansen Super Express.

Features
Third Enclosure as Entrance
Now, the ruins of Yamanaka Castle have been well developed and maintained as the Yamanaka-jo Castle Park by Mishima City, though the ruins have only earthen foundation. The entrance of the ruins is alongside the old Tokaido Road, and you can park at the parking lot inside when you visit the ruins by car. The entrance was also once that of the Third Enclosure which is now the town area. So, you will walk to the center of the castle by passing through the ruins of the moats for the enclosure. Most of the moats are dried, but part of them remains as a pond called “Tajiri-no-Ike”.

Second Enclosure as Pivot of Defense
From the pond, you have to walk up the stairs and winding slope to reach the Second Enclosure. The Second Enclosure was large and the connecting point with the center of the castle and the other parts. You can see good views of the area around, including Mt. Fuji from the enclosure. It is surrounded by high, thick earthen walls. It was the important point to protect the castle. Two more enclosures, including the North Enclosure, have been built to protect the Main Enclosure.
Main Enclosure as Center of Castle
You have to walk up more and across the bridge to the center of the castle, the Main Enclosure. The bridge, which is made of half wood and half earth, looks very interesting. The part of woods could be destroyed when a battle happened. The Main Enclosure is the highest place in the castle and has two tiers. It is thought that a high turret called “Tenshu Turret” stood on the upper tier. The enclosure is surrounded by deep valleys.
Group of Western Enclosures
On the west of the Second Enclosure, there are the West Enclosure and the West Turret over another small enclosure called the former West Turret. Though they were all connected by wooden bridges in the past, we can now go to these enclosures through wooden or earthen bridges. The West Turret is also a kind of enclosures, but once had buildings for defense as the frontline of the castle. Actually, the severe battle between Hojo and Toyotomi occurred there. Many of the latticed dry moats called Une-bori and Shoji-bori remain around the West Turret and the West Enclosure. They were originally deeper and the soil was exposed. The original surfaces have been buried and planted to protect them, as a result, the moats look very beautiful like a waffle with a great view of Mt. Fuji.
Taizaki-demaru defense strongpoint, others
Going back to the entrance of the ruins, you can also visit Taizaki-Damaru defense strongpoint to the south. This is a long and gently sloped enclosure which is also surrounded by earthen walls and Une-bori dry moats. The severe battle also occurred there, but it has a good atmosphere to walk around now. It may be a good idea to have lunch with a beautiful view of Mt. Fuji. You can also walk on the stone pavement of the old Tokaido Road below Taizaki-Dmaru. If you have time, I recommend that you visit the Sokan-ji Temple in the former Third Enclosure town area. There is the tomb of Naosue Hitotsuyanagi, a Hideyoshi’s commander, together with other tombs of Hojo’s soldiers.
