Enjoy the floating bridges and trampolines on the water until evening
About this spot
This aquatic obstacle course operates in 2026 from Saturday, July 4 to Wednesday, September 23 (a public holiday), from 9:00 to 17:00 (last entry 15:00, with closing days on some weekdays). Floating bridges, trampolines, slides and other obstacle features are linked together on the water adjoining Hasunuma Seaside Park, so you can play with your sense of balance while sending up plenty of spray. Play is based on wearing a life jacket, so it is set up for children who are not confident swimmers to try alongside a guardian. You can enjoy summery water play, moving your body right beside Kujukuri Beach with the sea breeze on your skin.
Tips
Last entry is 15:00 and closing is 17:00. It is reassuring to check fees, facility details and closing days on the official website before setting out. Bring clothes you do not mind getting wet and a bag to keep your removed clothes and valuables together.
Best time to visit
Entering at 12:00 lets you check in before the peak of the crowds and gives you plenty of play time until the 17:00 close
