2026 Kose Sports Park Swimming Pool Full Day Course

This is a one-day course centered around Kose Sports Park Swimming Pool (小瀬スポーツ公園水泳場) which operates from July 18 (Saturday) to August 16 (Sunday), 2026. The venue is located at Kose Sports Park in Kofu City. In the morning, enjoy science experiences at the nearby Yamanashi Prefectural Science Museum, then stroll through Maizuru Castle Park where Kofu Castle ruins remain, and finally head to the pool around noon. The pool features a 50m pool (9 lanes), a 25m pool (7 lanes), and an infant pool with a water slide, allowing children of all ages and abilities to enjoy water play at their own pace. Admission is affordable at ¥280 for adults, ¥140 for high school students, and ¥60 for middle school students and younger, with the added bonus that high school students and younger are free on Saturdays. Operating hours are 10:00 to 16:30, making it perfect to lightly visit nearby attractions in the morning and then spend the afternoon and evening enjoying plenty of water activities from noon onward. You'll use your mind at the science museum, exercise your body at the castle ruins park, and splash freely in the pool—a well-balanced day with varied activities. It's recommended as a standard summer vacation family outing and a one-day plan in the Kofu area for seeking coolness. With easy access from both within and outside the prefecture, it's a course that's easy for families visiting for the first time to plan.
