On May 26th, 1983, a magnitude 7.7 earthquake occurred in the Sea of Japan and 13 children from Aikawa Minami Elementary School (presently Kita Akita City) who had come to Kamo-Aosa Beach were swept away by the resulting tsunami and died. The people of Kamo-Aosa District helped in the rescue efforts and the monument is still honored by the villagers.
