Kōkū-kōen Station has two entrances, east and west, with the ticket vending on the third level.
The exterior of the whole three-storied station building is designed to look like a "Henri Farman" biplane, 1910's Farman III, which is the first official powered aircraft in Japan, the clock, above the entrance, as its propeller, and was selected as one of the top 100 Train Stations of the Kantō region by MLIT in 1998.
Several stores, such as Henri Farman Bakery & Cafe, Hōrindō Book store, and Senba21 Supermarket, are located in the station building.[3]
