Japan’s Forgotten Korean Forced Laborers: The Search for Hidden Wartime Graves in Hokkaido

Abstract

Abstract The return of remains of Korean forced laborers who died in Japan between 1940 and 1945 has been a major controversy for over half a century for Koreans. These deaths reveal the tragic consequences of Japan’s World War II forced labor system. Japan forcefully mobilized nearly 800,000 Koreans who were taken to at least 1,589 worksites in Japan and 381 worksites in Hokkaido. Over 10 percent of all Koreans forcefully mobilized throughout the empire are estimated to have died or disappeared, but the precise number of Korean forced laborers’ deaths inside Japan remains unknown. Until 1989, remains recovered from graves throughout Japan by local people were immediately cremated by Japanese Buddhist priests, making cause of death and precise identities forensically impossible. This account relates the first and only comprehensive effort to exhume Korean forced labor graves without immediate cremation, coordinated by Korean and Japanese activists and academics based in Hokkaido. This effort helped revive a neglected aspect of Korean forced labor history while focusing on the concerns of bereaved Koreans seeking the remains of their lost family members. Nevertheless, the project had serious limitations due to working in a difficult political environment and neglect of forensic science protocols in mass grave excavations and identification. This complex situation prevented identification of victims’ names and cause of death that could have held the Japanese government and companies involved accountable.
