Kokubu Airfield

Military Decommissioning. The airfield was an Imperial Japanese Navy air base that ceased all operations following the surrender of Japan at the end of World War II and the subsequent dissolution of the Japanese imperial military.

The site of the former airfield has been completely redeveloped and shows no visible traces of its original aviation infrastructure like runways or hangars. The land is now fully integrated into the suburban landscape of Takamatsu's Kokubunji-chō district. The area is occupied by a mixture of residential neighborhoods, agricultural fields, and commercial/industrial facilities, including the Shikoku Coca-Cola Bottling plant. A stone monument, the 'Takamatsu Naval Air Group Memorial' (高松海軍航空隊之碑), has been erected in the vicinity to commemorate the history of the site and the personnel who served there.

Kokubu Airfield, officially known as the Takamatsu Naval Air Group Kokubu Base (高松海軍航空隊国分基地), was a significant military air base for the Imperial Japanese Navy (IJN) during World War II. Established in December 1942, its primary role was as a training facility. Initially, it was used for training seaplane pilots, but it later transitioned to training pilots for land-based bombers (such as the Ginga 'Frances') and reconnaissance aircraft. In the final, desperate stages of the war, the base became critically important as a staging and operational point for Special Attack Units (tokkōtai). It was one of the bases for the Mitsubishi G4M 'Betty' bombers carrying the Yokosuka MXY-7 'Oka' rocket-powered, human-guided anti-shipping suicide attack planes.

None. The airfield was decommissioned at the end of World War II, and the land has been entirely repurposed for civilian use for over 75 years. There are no plans, discussions, or prospects for its reopening as an aviation facility.
