A grave for Japanese people is a place to bury the remains and worship’s place. Worshiping for ancestors, relatives who have died which have close relationships, loved between people who are still alive with those who have died. Worship for ancestors, relatives who have died is done in the family grave. During the Great East Asia War of 1941, Japanese soldiers and Japanese civilians married Indonesian women, settled and died in North Sumatra’s several areas. Because graves in various regions of North Sumatra are not family graves, the Japanese government built a cemetery in Delitua to place the bones of all Japanese who died in various regions of North Sumatra, and held a worship ceremony every year on April called iresai. As the organizer of the iresai tradition in North Sumatra. Japanese tombs in Delitua functioning as a historical markers of Japanese existence in North Sumatra, identity markers, social status, as solace, and soul enhancers for Japanese descendants who settled in North Sumatra. The local wisdom contained in the iresai tradition in the Japanese Delitua’s graves is the strong relationship between humans and gods with the aim of benefiting the deceased and living relatives.
