Boufuudou

Boufuudou (暴風道) was the fourth obstacle in KUNOICHI 2001's First Stage. Competitors had to walk across three beams that was curved to the competitors' 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 2002 in an effort to make the course easier.
