You can experience a castle on the Shirasu Plateau.

Walking down to Maintain Castle
Today, the ruins of Chiran Castle are accessible either from the Chiran Samurai Residences side at the foot the plateau or from the former Chiran Airport (where Chiran Peace Museum for Kamikaze Pilots is located) side on the plateau. If you choose the latter route, you may get an interesting experience.

When you want to go to a mountain (or hill) castle, you will usually go up or at least go on flat ground close to the castle. However, in the case of the route from the plateau to Chiran Castle, you will go down towards the castle and eventually reach the bottom of the deep dry moats. This is because of the special location and the construction method of this castle on the edge of the plateau. You will also look up at the tall enclosures looking like mountains from the ruins’ entrance which is actually the moat’s bottom.

Walking on Bottom of Deep Dry Moat
The dry moat is still about 20m deep which was filled in naturally by the collapsing volcanic ash since the period of the castle being active. Visitors first need to walk on the bottom of the moat which was also used as a path in the past. If you walk on the bottom from the entrance, two of the four primary enclosures, the Main and Kuranjo Enclosures are on the right, and the other two enclosures, Imanjo and Yunbajo Enclosures are on the left, as the signposts at the site show.

Protected Route to Enclosure
For example, if you want to go to the Imanjo Enclosure, you need to turn left and go up the path to it. However, the path doesn’t go directly to its entrance. Attackers first need to reach the wall of the enclosure and go along the side to reach it. That means the defenders of the castle would attack enemies from above before they reach the entrance. The entrance also had the defensive Masugata system. The inside of the enclosure is a flat square which has no buildings now, but you can see the earthen square shape of Masugata and earthen walls around.
