Buranchō (プラン跳) was an obstacle used in the First Stage of KUNOICHI 8. It consisted of a playground-style swing set on posts. Competitors had to swing and leap off with the correct timing to land on a floating raft (Ikadawatashi) that led to the final obstacle, the Shomouheki.
It proved to be the hardest obstacle in the First Stage, eliminating promising competitors such as Nishimura Chie and Higashi Rena, as well as many others.
Notably, the transition between the obstacle and the Ikadawatashi resulted in the rules for making contact with the water be relaxed somewhat, as competitor's feet could touch the water, as long as the majority of their bodies remained on the Ikadawatashi.
