The legend said, about 300 years ago, there was an old craftsman who made a horseshoe. One day, one great Samurai bought shoes, but at that time, there is only a shoe. The old man rapidly made another shoe and delivered to Samurai. Samura really liked his work and his honesty, and tried to pay him. However, the old man didn't receive the money because it was his fault. Samurai really appreciates his act and picked up the wooden board. He wrote "Bato-Kannon" and give him as the amulet.

When he brought back that board, the board started glowing. The old man really surprised, took this board to Myoshinji temple at Kyoto. He got the official writing of Myoshinji and enshrines the board at current place and built the temple.
