Mythology The inhabitants, who lived in the mountains of Kuma-gun in Higo, Kurino, Yokokawa, Hyokiyama, and Soo-gun in Osumi, defeated the court and did not donate their annual tribute to the court. Emperor Keiko visited the Kyushu region to subdue them and to make this clear. He departed from Kyoto, passed through Nagato and Toyokuni, then at Hyuga, he established Takaya-no-miya (near the western city) to fight the bear attack and settle down. On his way back to Kyoto, he stopped by Hinamori, nearby Kobayashi city. At that time, the hills surrounding the Mt. Idenoyama were said to have housed the royal family, and there was a beautiful lady called Izumihime. Izumihime poured tea made with the spring water from Idenoyama to the Emperor. The cup of tea made him comforted and healed the tiredness of the battle. The emperor and Izumihime grew warm affection one day. The time of return came and the Emperor departed for Kyoto. It is said that she mourned herself in the pond and turned into a snake as a guardian angel. Even now, the Benzaiten Festival is held every April to celebrate Mizugami-sama, and there is still a stone that is connected to the grave of Izumihime next to the cemetery in Oidemizu district. Excerpt of the legendary "Izumihime Monogatari" Inyoseki Rock Inyoseki is a couple rock in the Homanose river which is located in east part of Kobayashi city. You can find them in the downstream of Sannomiyakyo Gorge. The volcanic activity that was activated about 1.8 million years ago, deposited a large amount of volcanic ash and lava, which was formed by erosion by rivers. There is a 17.5-meter-high phallic-shaped yang stone (male stone), and beside it is a 5.5-meter-periphery-shaped gylinite (female stone).
