There is a cliff in the north of Saipan called the Longevity Cliff. In June 1944, the United States surrounded and entered the Saipan where the Japanese Navy Command was located. In order to escape the fate of the captives, the Japanese ordered the officers and men of the island, family and girls’ high school students to jump off the cliff and loyal to the country. . In the process of jumping off the cliff, people shouted "Long live", and Longevity Cliff got its name.
