The East Asia Anti-Japan Armed Front (Higashi Ajia Hannichi Busō Sensen; EAAJAF) was a Japanese far-left organization, influenced by the New Left movement.

On 14 August 1974, the EAAJAF tried to blow up the bridge over which Emperor Hirohito's royal train was travelling, which they code-named the "Rainbow Operation", but this was aborted because a member was spotted shortly before it was to be put into action.

[1]: 194  The following day Mun Se-gwang, a Korean-Japanese member of Chongryon and a far-left militant organization tied to the EAAJAF, attempted to assassinate President Park Chung-hee of South Korea.

[2] Members of the 'Wolf' (Ōkami) cell of EAAJAF planted two home-made time bombs containing 45 kilograms of explosives in a flower pot at the entrance of Mitsubishi Heavy Industries' head office block in the busy Marunouchi district of Tokyo.

[4] The explosion shattered the glass of the office block up to the eleventh storey, and that of buildings opposite including the headquarters of Mitsubishi Electric.

However, rightist Prime Minister Kakuei Tanaka and leaders of leftist parties remained silent about the incident.

[6] EAAJAF member and bombing participant Satoshi Kirishima, who had been hiding from the Japanese police since 1975,[8] revealed his identity in January 2024 in a hospital in Kanagawa, stating he wanted to die by his real name.
