Fuchawatari (風車渡) was the second obstacle for the first five Kunoichi tournaments. Competitors had to step on a thin beam in the shape of a windmill, seven centimeters wide, and traverse it while the obstacle spun like a carousel in order to clear the obstacle. This is one of the few obstacles in Kunoichi history to have been modified in every single tournament, varying from rule modifications to aesthetic changes. It proved to be deadly in it's first few tournaments, taking out upwards of seventy people in combination with Buyoishi in it's second appearance. It was replaced with a variant of SASUKE's Prism See-Saw in the 6th tournament, which eventually gave way to the deadly Danchigaubou in KUNOICHI 7.
KUNOICHI 1 Version
For the first KUNOICHI tournament, six obstacles made up the first stage, each of them proving to be extremely difficult. The second obstacle, Fuchawatari was composed of three spinning windmills. Unlike later versions of Fuchawatari this version proved to have the widest beam at about ten centimeters wide; however this was due to the fact competitors had to traverse three spinning windmills as opposed to one. Many competitors that failed this obstacle, did so by failing to jump from one windmill to the next; however many people still lost their balance while the windmills spun and fell into the water. Even competitors that cleared this obstacle normally spent so much time on it, that they would end up running out of time later in the course. This is one of only two variants of Fuchawatari to not disqualify competitors if they used their hands.
KUNOICHI 2 Version
After the horrible results of KUNOICHI 1 producers tried to make all six obstacles easier than their KUNOICHI 1 counterparts. When Fuchawatari returned for it's second tournament, the three original windmills had become one giant windmill. Even though producers tried to make the obstacle easier, they ended up making it much more difficult. The windmill shaped beam was now six centimeters wide, four centimeters shorter than the original. It spun even faster than the previous version, and competitors had to jump to a platform sticking out from the landing mats in order to clear. To complete the obstacle's grand modification, the course out areas of the windmill were sloped to prevent competitors from climbing back up onto the beam. (These were present in Kunoichi 1, but were virtually impossible to touch) Like the original version, competitors could use their hands, as Mizuno Yuko did. This version is arguably the most difficult variant of the obstacle. Competitors that reached the end could still manage to plunge into the water due to the speed at which the windmill was rotating. After all one-hundred contestants ran, it is estimated no more than thirty people cleared the obstacle, making the results of KUNOICHI 2 just a tad bit better than the first. It is worth mentioning that it did sleet during this tournament, and even though it did not occur during stage one, it was still cold, at around 4 degrees Celcius. Despite the differences between the first two versions, there was not a name change.
KUNOICHI 3 - KUNOICHI 4 Versions
From the third tournament onward, Fuchawatari was modified very little, most of the time for aesthetic purposes only. After the horrible results of KUNOICHI 2. The beam that competitors had to traverse was made a centimeter wider, making it seven centimeters wide. The windmill also spun much slower than it did in KUNOICHI 2 making some competitors have to wait before they could step on it. Despite these modifications to make the obstacle easier, the producers now made it illegal for competitors to use their hands. The sloped areas of the windmill remained unchanged for KUNOICHI 3. KUNOICHI 4 primarily saw aesthetic changes made to the obstacle. The beam competitors had to step on was raised a couple of centimeters, and the sloped areas were less sloped. The windmill also spun a little bit faster, but not nearly as fast as it's KUNOICHI 2 counterpart. The obstacle was also given a face-lift of sorts to make it look better, as there were no longer any curtains covering the plastic sloped area.
KUNOICHI 5 Version
While remaining very similar to the previous versions of Fuchawatri the fifth and final version of the obstacle was attempted to be made more difficult following Miyake Ayako's Kanzenseiha, however it ended being arguably the easiest version of the obstacle. The sloped portion of the obstacle was stepper than it had ever been (spare the original) and the beam was close to a meter high. The producers returned the speed of obstacle to that of it's Kunoichi 2 variant, however due to the height of the beam, many competitors were able to easily jump off onto the landing mat once they began to lose their balance. It is estimated no more than a handful of people failed this version, and as a result, the obstacle was replaced with a variant of Sasuke's Prism See-Saw in the next tournament.
