The theme park is built like a small castle town at the foot of a 1:1 replica of the Azuchi Castle (modern on the inside), seat of Oda Nobunaga, one of Japan's most important historical figures. The castle town consists of various buildings and areas such as a ninja museum, ninja maze, ninja adventure playground, sword gallery, various restaurants and theater venues where performances are held, including a ninja theater, a comical play and Oiran courtesan performances.
The theme park requires an admission fee before 5pm, but can be entered freely afterwards when the restaurants, shops and some of the attractions remain open until 10pm. In addition, a public hot spring bath is located next to the park's entrance.
The hot spring bath opens from 11:00.
Entrance to the castle town becomes free of charge after 17:00.
