Enjoy Plenty of Water Play Until Evening with Water Slides and Embankment Slides

About this spot

In 2026, Nagai Pool, an outdoor leisure pool within Nagai Park, operates from June 27 (Saturday) to August 30 (Sunday), 9 AM to 5 PM. The main attractions are the water slide and embankment slide, with children's cheers never ceasing as they slide repeatedly. Admission is affordable: ¥400 for adults (ages 16–64), ¥150 for children (ages 6–15) and seniors (65+), and free for children under 5, making it easy for the whole family to visit. Since everything is consolidated within Nagai Park in Higashi-Sumiyoshi Ward, you can walk from the morning museum and botanical garden visits, minimizing luggage. From noon until the 5 PM closing, you have plenty of time to thoroughly enjoy water play.

Tips

Operations end at 5 PM, so be mindful of wrapping up by late afternoon to feel secure. During summer vacation weekends, crowds are expected; arriving before noon is recommended to secure a good spot. Take sun protection measures and rest breaks frequently for a comfortable pace.

Best time to visit

Arriving around noon allows you to secure a spot before the peak crowding and enjoy plenty of time until 5 PM.
