The unimaginatively named Regional Wastewater Treatment Plant Square in Kunitachi City, Tokyo, is a plaza located on the roof of the Kitatama No. 2 Water Reclamation Center, with tennis courts, tennis wall, baseball field, basketball court, jogging course and other sports facilities.
In addition, there is a health playground and children’s playground equipment. Many recycled products are used in the park, such as soft woody pavement made of reused domestic conifer bark, and rubber chip pavement with high cushioning properties made of reused tire waste.
Access is a 10-minute walk from Yagawa Station on the JR Nambu Line.
