Toyokawa Airfield

The airfield ceased operations at the end of World War II. It was an integral part of the Imperial Japanese Navy's Toyokawa Naval Arsenal, which was largely destroyed by a major Allied bombing raid on August 7, 1945. Following Japan's surrender, the Imperial military was dissolved, and the site was subsequently converted for use by the post-war Japan Ground Self-Defense Force.

The site of the former airfield and naval arsenal is now completely occupied by the Japan Ground Self-Defense Force (JGSDF) Camp Toyokawa (陸上自衛隊豊川駐屯地). The original runways and wartime aviation facilities no longer exist. The land has been fully redeveloped into an active military base, housing various JGSDF units including engineering, anti-aircraft artillery, and training schools. While there is no fixed-wing airfield, the camp does contain the JGSDF Camp Toyokawa Heliport (ICAO: RJGT) for military helicopter operations. The ICAO code JP-1681 is an unofficial or outdated identifier and does not correspond to a currently active, standard airport.

Toyokawa Airfield was not a public or commercial airport. It was a private military airfield supporting the Toyokawa Naval Arsenal (豊川海軍工廠), one of the largest and most important ordnance factories for the Imperial Japanese Navy (IJN) during World War II. The arsenal produced a vast range of weaponry, including the Type 92 machine gun and various naval cannons. The airfield's primary operations involved military transport, liaison flights for personnel and officials, and logistical support for the massive industrial complex. Its history is directly tied to Japan's military-industrial effort during the war.

None. The site is an active, strategic military installation for the Japan Ground Self-Defense Force. There are no plans, discussions, or prospects for it to be converted back to a civilian or public-use airfield.
