Boufuudou (暴風道) was the fourth obstacle in KUNOICHI 1's First Stage. Competitors had to walk across three beams that was curved towards the left, while enduring a 55 mph wind from a high-powered industrial fan pointed at them.
The obstacle eliminated many competitors as the winds proved powerful enough to cause some competitors to lose their balance and fail, prompting the producers to replace it with Sekisho Michi in KUNOICHI 2 in an effort to make the course easier.
