Lawn Lunch Followed by the Bouncy Dome and Adventure Forest for Non-Stop Fun
About this spot
A free-admission prefectural park spreading at the foot of Miyagase Dam. It features the white mountain-shaped 'Bouncy Dome' beloved by children, an Adventure Forest packed with large play equipment, and a splash-water play area perfect for summer—offering full-day entertainment. A slow-moving road train within the grounds makes it easy for families with small children to travel down to the base of the dam.
Tips
The Bouncy Dome requires removing shoes to play, so slip-on footwear is convenient. On-site shops are limited, so bringing a packed lunch for a grass picnic is recommended.
Best time to visit
Allow 2 hours; the Bouncy Dome is less crowded in late morning to early afternoon
