The Maruta Bashi (丸太橋) is an obstacle used in the First Stage redesign of KUNOICHI 8. It is similar to the Danchigaubou from KUNOICHI 7, but it only consists of one log and there was no button for starting the Shoushi.

IN KUNOICHI 8, four people ran the First Stage at once. However, there were only three logs, so the competitor who was slowest on the Fuansou would have to wait behind to complete it.

Though it knocked out some competitors, it was not as deadly as the Danchigaubou due to the fact it was just one log and there was no extra need to rush it.
