The Koka region is historically recognized as the primary base for the Koka-ryu school of ninjutsu, distinct from the Iga-ryu style.
The onsite ninja house (Ninjutsu Yashiki) is an authentic structure that originally belonged to the Mochizuki clan, a prominent family of Koka ninja.
The village architecture was specifically selected for its proximity to deep mountain forests, which traditionally provided necessary cover for ninja training.
Many of the defensive features in the ninja residence, such as hidden escape routes, remain fully functional for visitor demonstration.
The site hosts a collection of over 200 artifacts, including authentic weapons and instructional documents on espionage.
Koka Ninja Village is a dedicated ninja-themed park located in the mountainous region of Shiga, a historic hub for the Koka-ryu ninja school. The site features the Ninjutsu Yashiki, an authentic 17th-century ninja residence relocated here, which is equipped with trapdoors, hidden corridors, and revolving walls. Visitors can navigate an outdoor obstacle course that includes wall scaling, water walking, and rope climbing. A museum on-site houses a collection of historical shuriken, scrolls, and traditional tools used by ninja practitioners. The village offers visitors the opportunity to rent traditional ninja uniforms to enhance the immersive experience. The surrounding forest environment serves as a practical setting for demonstrating ninja stealth and movement techniques.
