Shigetada Nishijima

When the Pacific War broke, Nishijima was arrested on December 8, 1941, and along with some 1,700 Japanese nationals, was detained by Dutch authorities and interned in Loveday, South Australia.

[6] After the surrender of Japan, Nishijima was sent to locate Sukarno and Mohammad Hatta (who were missing from Jakarta, as they were kidnapped by nationalist youths and held in Rengasdengklok).

[8] He then participated in a meeting at Maeda's house when the Indonesian Proclamation of Independence was drafted, and with his help copies of the text were printed by the Naval Office' press.

[5][10] After a rejection of his visa in 1951 due to "official sensitivity",[11] Nishijima returned to Indonesia in March 1953 in order to meet Sukarno to discuss war reparations.

[5] Nishijima later became a leader and pioneer at the Indonesian Study Group of Waseda University, which published works related to the Japanese military administration of Indonesia.

[18] Australian historian Greg Poulgrain remarked that "whoever in Washington authorized the return of Nishijima and his compatriots [to Indonesia] should also be seen as having contributed to Indonesian independence".

[3] During a 1958 visit by Sukarno to Japan, he gave Nishijima a letter meant to be a tribute to other Japanese agents Ichiki Tatsuo and Tomegorō Yoshizumi, both of whom died during the Indonesian National Revolution.
