Omonoimi no Kami
According to legend, a three legged crow, a sacred crow, was sent to observe the evil deeds of a being with long arms. The raven would make a sound of "Yes" to signal the appearance of the being and "Muya" when it did not appear. This is said to be why the Misaki Pass at the base of the mountain is called "Yuyamuya no Seki".
