nanaho United Park Oshihara (Oshihara Park) Water Plaza
About this spot
The nanaho United Park Oshihara (Oshihara Park) Water Plaza is a water-play area with a fountain in a 7.9-hectare park in Showa Town (昭和町). The water runs on weekends and holidays from May to September, 9:00 to 17:00, and use is free. Long loved locally under the former names Oshihara Park and Yume Park Showa, the park bustles with families on days off. The grounds hold a biotope, a lawn plaza, a play-equipment zone, natural and artificial turf grounds and a walking road, so when children tire of the water they can switch to hunting for insects and creatures or playing on the equipment. It stays open for a long stretch from the May holidays through September, which makes it easy to use as an outing destination in early summer or early autumn, avoiding the height of the heat.
Tips
Use is free. The water runs on weekends and holidays from May to September, 9:00 to 17:00, and the fountain may not be running depending on temperature and weather. Be sure to check the official page (https://www.yamanashi-football.com/pages/33/) before you set out. Shade is limited, so a pop-up tent or a tarp makes it more comfortable. In May and September the water can feel cold, so bringing one layer to put on gives peace of mind. Changes of clothes can be topped up at Aeon Mall Kofu Showa.
Best time to visit
Arrive at 13:30 and you can play right through to the 17:00 close, well into the hours when the sun goes down
