The Hikari Kikan was the Imperial Japanese liaison office responsible for Japanese relations with the Azad Hind Government that replaced the I Kikan. It was initially headed by Colonel Bin Yamamoto, later replaced by Major General Saburo Isoda.

The Hikari Kikan recruited Ceylonese, Indians, and other South Asians domiciled in Japanese-occupied British Malaya and Singapore for espionage missions against the Allies during World War II.
