Inariyama Park was once an American military facility; part of Johnson airport. Nearby Sai no Mori Iruma park and Johnson Town were also part of Johnson airport. After Inariyama park was returned to Japan, it was made a Saitama prefectural park, in 2002.  It is located close to the current day Japan Army Self Defence Force Iruma Air Base. The Sayama Municipal Museum and Kome To Cha Cafe are on the south west corner of the park.

Until 2018 they didn’t have much for kids, but they added a small playground suited to toddlers.

Cherry Blossoms

The park is lush all year round, but during cherry blossom season it is effervescent with its 300 mature yoshino cherry blossom trees. And its a really popular place for hanami. However, in 2023, the park asking people to refrain from picnicking under the cherry blossoms. There are also some yaezakura, the late blooming type, in the park too. 


Cherry Blossom Festival

This year for the first time since the pandemic began, they will have a cherry blossom festival. The festival is scheduled for Saturday April 1st and Sunday April 2nd. However, as they are asking people to refrain from partying in the park, there is a chance they won’t have food trucks this year. As of March 14th 2023, the park still hasn’t released the finer details of the festival, just their intent to have one.

  1. I lived there 1970 – 1973.

  2. Great to see the park through your beautiful pictures. I was stationed at Johnson from 1968-72. It began as Johnson AB after the Army Air Force moved into Japan’s Iruma Air Base postwar. The base was joint use through the years I was there, serving both the USAF and the JASDF. The JSADF controlled the air field and flight operations of the base. USAF had many facilities on the main base. Johnson served primarily as a housing area for both Johnson and Yokota military personnel (Yokota did not have a lot of room for on base housing). The Hyde Park Annex was just outside the back gate and Inariyamakoen Station. The cherry blossom trees were spectacular along the road that led to Irumagawa and Sayama. We first lived in a small rental in Irumagawa. The house was near the large hill at the rear of Hyde Park with a view point that overlooked Irumagawa and Sayama. Hard to imagine it is all gone, even after all the years. I have a nice picture of Inariyamakoen Station and the Sayama viewpoint if you can email me directly.
