The Howa Type 64 battle rifle (64式自動小銃, Roku-yon-shiki-jidou-shoujuu), referred to as the Type 64 7.62mm rifle (64式7.62mm小銃), is a Japanese battle rifle used exclusively by the Japan Self-Defense Forces and the Japanese Coast Guard. It is a gas-operated, selective fire weapon which is chambered for the 7.62×51mm NATO round and uses a detachable 20-round box magazine.
The Type 64 has never been exported due to Japan's strict anti-hardware export laws. It has been superseded by the more advanced Howa Type 89 from 1989 to 1990, but is still in service with all branches of the Self-Defense Forces and the Japanese Coast Guard. A small number of Howa Type 64 marksman versions have been used by the Special Armed Police unit.[better source needed]
