Enjoy the 25-Meter Pool, Current Pool, and Water Slides Until Evening

About this spot

Waiwai Pool, an outdoor leisure pool at Nagasaki Prefectural Comprehensive Sports Park, operates from July 18 (Saturday) to August 31 (Monday) 2026 (closed on Wednesdays during the period). After swimming laps in the 25-meter pool, drift peacefully along the 150-meter current pool with a float ring, offering fun for everyone from small children to adults. The water slides and rock slides are thrilling, while the shallow adventure pool is safe for young children. The pool shop provides snacks and beverages to recharge during water play. Unlike urban theme park pools, the natural surroundings and spacious atmosphere make it a charming summer destination.
