2026 Koshigaya City Gymnasium (越谷市総合体育館) Heated Pool Full-Day Course

A full-day course starring the heated pool inside Koshigaya City Gymnasium (越谷市総合体育館), where you can swim properly from the morning. It is open year-round on a four-session system, including a session from 9:30 to 12:00, so it is easy to plan without worrying about the weather. In the morning, first walk the paths of Koshigaya Lake Town (越谷レイクタウン), laid out around a regulating pond said to be among the largest in Japan, and spend quiet morning hours taking in the waterside scenery. Then continue to Fureai Bridge (ふれあい橋), which spans the pond, and enjoy the lakeside view spreading out from the bridge. Once the walk has got your body moving pleasantly, it is finally time for the heated pool at Koshigaya City Gymnasium. Enter in time for the 9:30 opening and swim solidly until the session ends at 12:00. A day perfect for families who want to concentrate their water play in the morning.
