In April 1975, Kirishima was put on a nationwide wanted list and went on the run after he allegedly helped set up a bomb that blew up part of Economic Research Institute of Korea building in Tokyo's
Ginza district. No one was killed in the bombing. On May 19, 1975, Masashi Daidōji of the Wolf Cell, Kurokawa, and five other key members of the EAAJAF were arrested. Kirishima's house key was in the possession of Kurokawa, which brought Kirishima to the attention of the police. The
Public Security Bureau charged Kirishima with violation of the Criminal Regulations to Control Explosives Law, and issued
wanted posters of Kirishima throughout Japan. Altogether, Kirishima is suspected to be involved in seven bombing cases, including four against
Hazama Corporation. Upon his arrest, he denied responsibility for the Ginza bombing but admitted his involvement with at least one Hazama bombing. This was the last time Kirishima contacted friends, family, or acquaintances. When Kirishima revealed his identity before his death, it was discovered that he had gone into hiding, that he had been living under the
pseudonym "Hiroshi Uchida" for decades, that he had been working as a live-in worker at a construction company in
Fujisawa City,
Kanagawa Prefecture, and was living alone in an old wooden two-story dormitory near his workplace. Kirishima was paid in cash and did not possess a mobile phone to avoid detection. He also did not own a
driver's license or
health insurance. His nickname was 'Uchii', and was known to be a big music fan, with
James Brown being among his favorites. Once a month he would turn up at a music event at a bar in Fujisawa, where he would dance. Neighbors were unaware of his true identity, with one describing him as a "calm and serious" man, who would occasionally play guitar in his room. ==Discovery and death==
