Naval Air Facility Atsugi (IATA: NJA, ICAO: RJTA) is a joint military air base in Kanagawa Prefecture, Japan, shared by the Japan Maritime Self-Defense Force (JMSDF) and the United States Navy. Located near the cities of Ayase and Yamato, about 35 km southwest of Tokyo, it is one of the largest and busiest military airfields in the region. Originally a Japanese naval air base, it was taken over by US forces after World War II and today hosts Carrier Air Wing Five and various JMSDF squadrons.
💡 Local Tip
The base is surrounded by dense residential areas, so aircraft noise can be intense; if you're plane-spotting, the north end near Ayase offers good views of the runway, but be respectful of local residents and check the base's official website for rare open house days.
🚖 Getting There
Public transportation is the best way to reach the area: take the Odakyu Enoshima Line to Yamato Station or the Sotetsu Main Line to Ayase Station, then a taxi for the final few minutes. The base is about 30–40 minutes from central Tokyo by train and taxi. Note that parking and access to the base itself are restricted to authorized personnel.
