2026 Tsumakoi Water Park (つま恋ウォーターパーク) Full-Day Immersion Course

A full-day course centered around Tsumakoi Water Park (つま恋ウォーターパーク) in Kakegawa City, operating from July 18 to September 6, 2026. Since September operates weekends only, July and August are recommended for families who want plenty of weekday playtime. The morning features popular spots in Kakegawa's city center, warming up with views from the castle tower and hands-on animal encounters. From noon onward, enter Tsumakoi Water Park and drift along the 150-meter lazy river, try the three water slide varieties (River Ride, Water Slider, Speed Slider), or use the diving pool for kids who want to move vigorously. With closing at 5:00 PM, it's easy to plan an evening departure after fully enjoying water play. Some days extend to 9:00 PM, making night pool visits a goal for next time. Parking is 800 yen per car, convenient for driving. Easy access from Kakegawa Station makes this ideal for day trips from within Shizuoka Prefecture or beyond. Head out with your whole family to splash in the water and create summer memories.
