Ugoku Kabe (Moving Walls)
From the 1st to 4th Competition it is the third set of the panels in the Spider Walk. This set of the walls is automatically moving up and down slowly.
Note: In 5th and 6th competition, there are two sets of the panels (the second and fourth set) moving up and down in the Spider Walk, but TBS officially does not make them an independent obstacle or call them the "Moving Walls", but just considers the whole Spider Walk as one obstacle only.
