Bizan (Gifu City) is said to have been named by Sanyo when he visited his pupil in Mino Province and stopped by at the residence of the Kono family, a village headman in Nishiawano, on his way home, as he was impressed with a graceful appearance of the mountain like a woman's beautifully trimmed eyebrows.
