Yokohama Naval (Tomioka) Airfield

The airfield ceased military operations following the surrender of Japan at the end of World War II. Post-war, the site was returned to the Japanese government and was subsequently decommissioned and redeveloped for civilian use due to the rapid urbanization of the Yokohama area.

The site of the former airfield has been completely redeveloped and is now an integrated part of the urban landscape of Kanazawa Ward, Yokohama. There are no visible remnants of the runway or military facilities. The land is now occupied by a mixture of public, residential, and commercial properties, including Tomioka Sogo Park (富岡総合公園), Yokohama Municipal Kanazawa Sogo High School (横浜市立金沢総合高等学校), a large research facility for the Mitsubishi Chemical Group, and numerous residential apartment complexes (danchi).

Established on October 1, 1943, on reclaimed land, the Tomioka Airfield was a base for the Imperial Japanese Navy's Tomioka Naval Air Group (富岡海軍航空隊, Tomioka Kaigun Kōkūtai). Its primary mission was the training of pilots for reconnaissance seaplanes, such as the Mitsubishi F1M ('Pete') and the Aichi E13A ('Jake'). The base played a role in the naval air defense of the Tokyo Bay area during the final stages of the war and was a target for US bombing raids in 1945. After Japan's surrender, the facility was briefly taken over by Allied occupation forces before being dismantled.

None. The land is fully and densely developed with civilian infrastructure. There are no plans, discussions, or prospects for reopening the site as an airfield.
