In a spiritual mountain of the Tokushima's Shugendō practitioners, there was a battle between the different sects. In the legend called the Furudanuki Kinchō Giyuu Chinsetsuseki (古狸金長義勇珍説席), there was a scene of rock-throwing, and since rock-throwing was a military technique of the Middle Ages, there's the theory that the tale of the battle between tanuki was based on a battle between Shugendō practitioners on Mount Tairyūji and Mount Tsurugi. In this theory, the Shugendō practitioners on Tairyūji would be based on Kinchō and the Shugendō practitioners on Mount Tsurugi would be based on Rokuemon, suggesting that it's related to a clash that erupted when different schools of Shugendō from two different bases, the ones from Mount Tairyūji trying to move north and the ones from Mount Tsurugi trying to move south, collided with each other.
