Disguised as an ordinary traditional residence from the outside, the Koka Ninja House (Koka Ninjutsu Yashiki) preserves the ingenious defensive design of genuine ninja history. Dating back nearly three centuries, the residence is equipped with intricate hidden passages, revolving walls, and deceptive traps engineered to outwit intruders and ensure a swift escape. Visitors can freely explore the historic timber rooms, uncovering the tactile craftsmanship and stealth tactics that once protected Japan's famed covert operatives. It is a thrilling, hands-on journey into real ninja lore that brings feudal espionage to life.
