The Spider Walk (スパイダーウォーク) is an iconic obstacle that has been used in the Second Stage from SASUKE 1 to SASUKE 17, and SASUKE 28 onward. It is derived from an entirely separate event in Kinniku Banzuke.

The obstacle requires the competitors to traverse the space between two parallel walls without touching the ground or grabbing the top part of the walls. The space between the walls are 1.2m, enough for the competitors' hands and feet to reach (except for Tanabe Chie in SASUKE 2, when she couldn't prop her feet to the walls).

Four different versions have been used, with Yamamoto Shingo being the only competitor to attempt all four.

After Nagano Makoto's kanzenseiha, it was modified into the Jumping Spider in the First Stage.

SASUKE 1-4 Version

In the first four SASUKE tournaments, the Spider Walk appeared as the first and longest obstacle, sometimes taking as much as half of the allotted time limit. The obstacle had 8 sets of parallel walls, divided into 3 parts:

  • the Spider Walk (スパイダーウォーク) (the first 2 walls)
  • the Ugokukabe (動く壁) (the third wall), and
  • the Spider Climb (スパイダークライム) (the last 5 walls; not to be confused with the Spider Climb, which would appear as the first obstacle in the Final Stage from SASUKE 5 to SASUKE 17, and then from SASUKE 29 onward).

Competitors must traverse forward in the first part, through a moving wall as the second part (Ugokukabe), and up in the third part (Spider Climb). Then, competitors must grab a fireman's pole and finally dropped down to the landing platform.

Both the Ugokukabe and Spider Climb were counted as individual obstacles in SASUKE, and were counted as parts of the Spider Walk during the broadcast of Ninja Warrior.

In its first three tournaments appearance, throughout the entire obstacle, there were only mats to fall on. In SASUKE 4, the first half of the obstacle was filled with the water, and the second half of the obstacle (starting from the Spider Climb section) was filled with mats.

This version of the Spider Walk was considered as the toughest and most brutal than any other versions of the Spider Walk in SASUKE, as the obstacle eliminated more than half of the number of the competitors who attempted it.

A toned-down version of this version of Spider Walk was also used as the second obstacle in BLUE Stage (Second Stage) on KUNOICHI 9 and KUNOICHI 10, with the Ugokukabe and Spider Climb sections being removed in favor of a three panel-long straightaway. The design was somewhat similar to the Spider Wall/Spider Jump, which was used as the fourth obstacle during qualifying and semifinal on American Ninja Warrior 1 and American Ninja Warrior 2, with the walls were arranged in a straight line.

SASUKE 5-6 Version

After Akiyama Kazuhiko's kanzenseiha in SASUKE 4, the Spider Walk was moved as the second obstacle, and was shortened to five large sets of panels, while the second and fourth panels moved independently of the others (which was known as the Ugokukabe (動く壁)).

Since the debut of this version in SASUKE 5, the area under the whole obstacle was filled with the water.

In its first tournament, the obstacle took out Takeda Toshihiro and Yamada Katsumi (both of them had their feet slipped while moving to the second panel). However, all competitors cleared this obstacle in the next tournament.

SASUKE 7-17 Version

With the Second Stage's redesign in SASUKE 7, the Spider Walk was modified. This time, the walls were arranged like an upside down "J". Competitor must go 3m upward, then 5m horizontally, and 5m downward. After that, instead of reaching for a fireman's pole, competitors must reach a horizontal bar to make the dismount to the landing platform.

Competitors were also provided with sticky spray at the start of the obstacle, and they could use it before attempting the obstacle, in order to prevent their hands/feet got slipped. However, several competitors skipped the spray entirely, in order to save time.

With the introduction of the Chain Reaction in SASUKE 7, competitors must wear gloves (for safety reasons) while attempting the Chain Reaction, and they must discard them before attempting the Spider Walk. This particular rule came into play, when Yamada Katsumi forgot to take off his gloves during the Spider Walk in SASUKE 12, and although he could complete the Second Stage with seconds to spare, he was then disqualified (see Yamada Katsumi's Glove Disqualification).

Although only a handful of competitors failed on this version of Spider Walk, it had been eliminated some top competitors such as: Kane Kosugi, Nakayama Kinnikun, and Honma Kota

SASUKE 28- Version

In SASUKE 28, the Spider Walk returned to the Second Stage. The walls were the same as the one used on the Jumping Spider, but without the trampoline and with a pair of panels added at the end. The extension was placed a few inches lower than the fourth wall.

In SASUKE 30, the obstacle was modified with the extended wall being the same height as the fourth wall, and with the addition of the Spider Drop, where competitors must drop down to another set of panels to reach the end.

In SASUKE 31, the Spider Drop was modified with the replacement of the black mats by a curved wall, and was made into an official individual obstacle, rather than being a part of Spider Walk.

So far, only one competitor has failed this version, which was Nagasaki Shunsuke in SASUKE 34, and so it was seen more as a time waster, sapping time away before the BackstreamDrew Drechsel almost failed at the Spider Drop portion in SASUKE 30, as his legs slipped on the lower set of panels. However, he managed to recover and clear the obstacle.
