Showa Commemorative National Government Park (国営昭和記念公園 Kokuei Shōwa Kinen Kōen) is an expansive park in (far) western Tokyo Prefecture that spans the cities of Tachikawa and Akishima.

The park is especially popular with families, with many facilities aimed at entertaining children (and grown-up children) of all ages. There’s futuresque bouncy castles, faux Maya pyramids, a water park in the summer, huge open spaces for sports and more than 11km of bicycle paths with bicycles for rent.

The park is named for the Showa emperor—better known as Hirohito in the west. On the site of a wartime airfield, the park was opened in 1983 to commemorate the 50th anniversary of the emperor’s reign.

Note the park does have a small entry fee, but certainly, worth every yen—it still checks the cheapo box!
