Tachikawa Air Base was a significant military installation located in Tachikawa, Japan. Established during the post-World War II era, it served as a base for the United States Air Force and played a crucial role in various operations throughout the Cold War. The base was primarily used for air defense and logistical support. In 1977, Tachikawa Air Base was officially closed, and the land was repurposed for civilian use. Today, the site includes parks and residential areas, reflecting the transition from a military facility to a community space. The history of the base remains an important part of the local heritage.
