The Prism See-Saw (プリズムシーソー), known as the Prism Tilt on English broadcasts, was an obstacle introduced in SASUKE 13's First Stage as the first obstacle, replacing the Yamagoe from the previous tournament.

Competitors needed to jump over a small pit onto a large triangle which was supported by an axis in its center. The addition of weight on one side of the triangle would tilt it into the water, so it needed to be crossed quickly. This obstacle required both speed and balance.

While it eliminated a fair amount of competitors, it was replaced in the following tournament with the Ensuitobi.

Other Appearances

The Prism See-saw reappeared in KUNOICHI 6, as the second obstacle of the First Stage, and was known with a different name as the Sankaku Bashi (which also called as the Prism Tilt during the broadcast of Women of Ninja Warrior).

Later, the Prism See-saw (called as the Prism Tilt) appeared on American Ninja Warrior 5, as the third obstacle in Baltimore. However, unlike in SASUKE, the triangle's weight on either sides was equal.
