The final resting places for the spirits of the Byakkotai, who died in the Edo period Boshin Civil War
During the Boshin Civil war, the Byakkotai second brigade, consisting of twenty 16-17 year old boys retreated to the mouth of Tonokuchi-hara, through the secret Takizawa pass. They arrived on Iimoriyama, and from the mouth of the pass saw the tower of Tsurugajo castle engulfed in black smoke. "As the castle falls, so shall we for our lord" said the boys, and with that they committed ritual suicide. Only one of the 20 boys, named Iinuma Sadakichi, survived. This place has become well known for the story of the loyalty and tragedy of the Byakkotai Brigade. Twice a year, in the spring and autumn, a memorial service and sword dance is held to comfort the spirits of the dedicated Byakkotai.
