Koka Ninja House

甲賀流忍術屋敷

Koka Ninja House preserves the former main residence of the Koka Mochizuki clan on its original site in Shiga. Official pages emphasize that it is not a relocated or newly invented tourist set, but a maintained historic building open to the public since about 1955. Guests can walk the three-story house, view ninja tools and documents in the museum rooms, sample medicinal herb tea, and add shuriken or mechanism experiences for an extra fee. Check access, hours, and experience options before visiting this compact history stop in Koka.
