My latest contribution to the KA Japan website; kajapan.org. A round of parks where the kidlets can play with water in the Greater Tokyo Area, which includes Tokyo, Kanagawa, Chiba and Saitama. via Parks with Water Play in the Greater Tokyo Area | K-A International Mothers in Japan. PREVIEW: Summer has started and the heat is already on! Thankfully, there is a huge selection of parks with water play areas in the Greater Tokyo Area to help us cool down. Water play includes such things as spray pads, spray pools, paddling pools, wading rivers, splash pools, spray grounds, lazy rivers or other recreational water environments. It does not include swimming or bathing pools. The Greater Tokyo Area refers to the metropolis of Tokyo and its surrounding highly populated prefectures of Kanagawa, Chiba and Saitama. Parks with water play are introduced by area, quoted by KA Mother who introduced or recommended them, with some additional information added.
