Motosu Airfield

The airfield was a military installation of the Imperial Japanese Army. It was closed and dismantled following Japan's surrender at the end of World War II and the subsequent disbandment of the Japanese military.

The site is no longer recognizable as an airfield. The land has been completely repurposed since the end of the war. A significant portion of the former airfield is now occupied by a large-scale solar power plant known as the Motosu Solar Park. The remaining land has been converted into agricultural use, primarily rice paddies and other fields, with some industrial and commercial facilities built on the periphery.

The facility was historically known as the Imperial Japanese Army Motosu Airfield (陸軍本巣飛行場, Rikugun Motosu Hikōjō). Constructed around 1943-1944 during the late stages of WWII, its primary purpose was to serve as a training base for army pilot cadets and to station air defense units of the 1st Air Army. It was a key military installation for training and preparing for homeland defense in the Chūbu region of Japan. The unofficial ICAO code JP-2099 is a modern designation used in some databases to mark the historical location, not an official code used during its operational period.

There are no known plans, discussions, or prospects for reopening the site as an airfield. The land has been fully and irreversibly redeveloped for agricultural, industrial, and renewable energy purposes for over 75 years, making any potential restoration for aviation use economically and logistically infeasible.
