Airwalk (エアウォーク), also translated and called the Sponge Bridge House of Cards, was an obstacle from the original single-stage version of KUNOICHI that aired on Kinniku Banzuke. Due to the difficulty of the previous areas, the obstacle was never attempted.
The obstacle's concept revolved around competitors having to walk across a set of Styrofoam boards, not unlike the Sponge Bridge event or later Tourenban, but these boards were arranged as a small horizontal square board atop two small, rectangular vertical boards, which were arranged into a set of five to six of these board formations. At first, the support boards would be facing the competitors, but around the halfway point of the obstacle, the set would turn 90-degrees to the left, but the boards' formation would remain the same. This would potentially result in the formation becoming more unstable as now the boards would be at the sides of the competitors rather than facing them.
Originally, the obstacle was made up of five board formations and was the seventh obstacle, but was shifted over to become the sixth obstacle in KUNOICHI 2000. In that tournament, while several obstacles were made easier, Airwalk arguably became harder as an additional board formation was added, lengthening the first section to four before the turn had to be made.
However, whether this would have made the obstacle more difficult is debatable, as ultimately, it would once again go unattempted and would be removed from KUNOICHI come the 2001 course reboot. The obstacle's concept however, would ultimately be succeeded by the implementation of Tourenban into the 3rd Stage come KUNOICHI 2003, an obstacle that still remains on the course circa KUNOICHI 2018 and that has been adapted into several international formats.
