What this is
Daytime swimming bleeds into a DJ-soundtracked night pool as Oohama Park Pool transforms across the day — sunset light giving way to full illumination, bubble effects, and a festival atmosphere that runs well into the evening. Splash Circus is an adults-only pool festival pairing water activities with live DJ sets, gourmet food stalls, and photo-ready installations. The gender-tiered pricing is unusual but common for Japanese pool festivals of this type, making it notably cheaper for women.
Who should go
Adults in their 20s and 30s who enjoy the overlap between club culture and summer festival vibes. Not suited to families or anyone expecting a conventional music venue — you will be in and around water for most of the day.
Good to know
Tickets are likely sold via eplus.jp or pia.jp — both accept foreign credit cards, and convenience store pickup at Lawson is the most reliable collection method for visitors without a Japanese delivery address. This is an outdoor pool venue so there is no bag check in the traditional sense, but lockers are typically available at pool facilities — bring coins (¥100) for locker use. Age verification (18+) will be enforced at the gate, so carry your passport or a photo ID. The event runs across multiple days with a four-day all-pass option, so check the full schedule if you want to attend more than once. Sunscreen is essential for the daytime portion; reapplication after water activities is easy to forget.
