2026 Wanpaku Okoku (わんぱく王国) Water Play Plaza Full-Day Course

This is a neighborhood outing course centered on the water play plaza near the main gate of Wanpaku Okoku (わんぱく王国) in Hannan City, open from Monday, June 1 to Monday, August 31, 2026. Conveniently located right by Yamanakadani Station (山中渓駅) on the JR Hanwa Line, it's a park spread through lush, green mountains. In the morning, first stroll around Yamanakadani Station, enjoying the peaceful scenery while walking the promenade known for its cherry trees. Next, visit Hata Shrine (波太神社), which stands in the same Ishida district as Wanpaku Okoku, and spend a moment in its quiet grounds. After lunch, it's finally time for the water play plaza at Wanpaku Okoku. Enjoy splashing in the water to your heart's content under the summer sun. Since getting around is a short trip completed entirely by train and on foot, you can plan it without stress even with young children.
