The Himenoga Pond, located in the northern field of Mt. Sanbei, is home to thousands of Japanese irises, which are designated as a natural landmark by the prefecture, and are in full bloom from mid-May to June.
A sad legend says that once a lady named Oyuki, the daughter of a named man, was about to be married to a bandit, and a young brave man came to save her, but he was killed, and, fleeing the bandit, the bride jumped into a pond and followed the young man.
The large rock called "Himenoga Ishi" (lit. "a stone of fleeing princess") by the pond is said to be the stone that broke in half when the young man was stabbed and killed by the bandit.
It is said that if you drop a twig into the slit in the stone and it falls without getting caught, your love will come true.
