In 1807 of the Bunka era, an incident occurred that a Russian fleet attacked Rishiri, which was placed under the Shogunate's rule. The Shogunate immediately ordered the Aizu Domain to guard the north, and the Aizu Domain dispatched approximately 250 domain warriors, but there was no direct armed conflict with Russia. However, due to the harsh natural environment of Rishiri at that time and the shortage of food, etc., several domain warriors ended up burying their bones in this land. On Rishiri Island, graves remain in 3 places: Kutsugata-aza-Tanetomi-cho, Oshidomari-aza-Sakae-cho, and Oshidomari-aza-Honbetsu. The two people sleeping in the grave within the grounds of Tanetomi Bicycle Parking and Car Park died on the ship on their way back after finishing the Karafuto guard.

* A public toilet is available within the grounds of Tanetomi Bicycle Parking and Car Park.
