Iruma Air Base is a major air base of the Japan Air Self-Defense Force (JASDF) located in Sayama, Saitama Prefecture. It serves as a crucial hub for air defense operations in the Kanto region and is particularly famous for its annual air show, which is one of the largest and most popular aviation events in Japan. This event attracts hundreds of thousands of visitors eager to see aerial displays, static aircraft exhibits, and military demonstrations.
Visitors consistently praise the air show for its impressive aerial performances, including precision flying by the Blue Impulse aerobatic team, and the opportunity to see various JASDF aircraft up close. Many reviewers highlight the family-friendly atmosphere and the chance to interact with personnel. However, some visitors note that the base itself, outside of the air show, offers limited access and attractions for the general public, making it primarily a destination for specific events or aviation enthusiasts.
For those attending the air show, it is highly recommended to arrive early, as crowds can be immense. Bringing your own food and drinks is advisable due to long queues and potentially high prices at on-site vendors. Comfortable walking shoes are essential, as the base is large and involves considerable walking. Consider bringing a portable chair or blanket for watching the aerial displays. The best time to visit is during the annual air show, typically held in November, for the full experience. Outside of this event, public access is generally restricted.
The base is located at 2-3 Inariyama, Sayama, Saitama Prefecture. Reviewers often mention that the base is accessible by public transport, with Seibu-Shinjuku Line's Inariyama-koen Station being the closest. From the station, it's a short walk to the base entrance, especially during the air show when special arrangements and signage are usually in place. Driving to the air show is generally discouraged due to severe traffic congestion and limited parking; public transport is the preferred method.
A common complaint during the air show is the overwhelming crowd size, leading to long lines for everything from food to restrooms, and difficulty getting a good viewing spot. To mitigate this, arriving several hours before the main events begin is crucial. Also, be prepared for potential delays when leaving the base due to the sheer volume of people.
