The Yureru Hashi (揺れる橋) was a First Stage obstacle from the first seven SASUKE tournaments. The obstacle was a bridge supported on a horizontal axis. There was a wooden wedge in the middle to prevent competitors from simply running down the center. Its success rate was in the high 90s towards the end of its life and was replaced with the Ōdama in SASUKE 8. This obstacle was similar to the obstacle used on KUNOICHI 3, and renamed as Fuandou

After 15 years hiatus, this obstacle returned. This time, as the third obstacle in Red Stage (First Stage) of KUNOICHI 10, and renamed as the Shaking Bridge (although during the broadcast, the announcer sometimes called it as Yureru Hashi). The only difference is that the wedge in the middle is larger and was secured with velcro (hook and loop fastener) as well as the material differs.

On Ninja Warrior, this obstacle is called the Balance Bridge (or the Shaking Bridge during the broadcast of SASUKE 1), which was a similar obstacle from SASUKE 11.
