Also known as: Hakone Lake, Ashinoko Lake, Manji Pond
Legend has it that during the Nara Period, when the lake was still called Manji Pond, it was home to a poisonous nine-headed dragon. In order to appease the dragon's anger, the villagers would offer maidens to it as sacrifices. Holy Priest Mangan, who had come to Mt. Hakone to practice asceticism, heard the tale and bound the evil dragon to a rock at the bottom of the lake in order to save the villagers. The dragon promised to protect the mountains and villages, and thus reformed, became a dragon god. Thereafter the villagers fed the dragon red rice instead of their daughters.
