If you demand a great park in Tokyo, your search is over! This park may not be as well known as the other parks in Tokyo but $ 30 cost should be! Involved with one of home loan houses parks I have visited and, wow, what a great list of fun-based activities. This park was formerly the location of the Tachikawa air base (about 566 hectares – 5.66 million square meters!) This park is divided in a very series of 5 zones (a, b, c, d and e). The main part of the park is approximately 1.7km by 2.3km.
