Susaki Toyosu Airfield

A combination of factors led to its closure: 1) Obsolescence: The small airfield became inadequate for the larger and faster aircraft being developed. 2) Development of Superior Alternatives: The opening of the larger Tachikawa Airfield (1922) and Tokyo Airfield (Haneda, 1931) rendered Susaki redundant. 3) Urban Expansion: Located on valuable reclaimed land near central Tokyo, the site was repurposed for urban and industrial development as the city expanded.

The site of the former airfield has been completely absorbed into the urban fabric of Koto Ward, Tokyo. The area, which includes parts of the modern districts of Minamisuna, Kiba, and Toyo, is now a densely populated residential and commercial zone. It contains apartment buildings, schools, shops, and Kiba Park. There are no physical remnants of the airfield, though some local monuments or plaques in the area may commemorate its history.

Susaki Airfield was one of Japan's first civilian airfields and a cradle of Japanese aviation. Established around 1916 on reclaimed land in Tokyo Bay, it was the base for the Imperial Flying Association. It served as a primary center for flight training, air mail experiments, and public flight demonstrations. Notably, it was the departure point for the first air mail flight between Tokyo and Osaka in 1919. The airfield played a pivotal role in popularizing aviation and training Japan's earliest generation of civilian pilots before the establishment of more formal national airport infrastructure.

None. The site is a highly developed and densely populated urban area in central Tokyo. There is no physical space, economic justification, or political possibility for reopening an airport at this location.
