Marine World Night Aquarium 2026: Dates, Tickets and Access

This translation was prepared with AI assistance and reviewed by the editorial team.

Marine World Uminonakamichi’s Night Aquarium runs on selected dates from July 18 to September 23, 2026. On event days the aquarium is open 09:30-21:00, final entry is 20:00, and the lighting changes to night mode at 18:00.

There is no separate night surcharge or daytime-nighttime changeover. You can enter earlier, see the aquarium in daylight and stay for the evening atmosphere. Check the exact event date and your return train or boat before traveling because night operation is not daily.

2026 Night Aquarium dates

Dates are July 18-20, July 25-26; every day from August 1-23 plus August 29-30; and weekends and public holidays through September 23. The aquarium stays open until 21:00 on these dates. From 18:00, darker tank lighting lets visitors observe different animal behavior. Show times vary by date and should be checked on the official schedule.

Admission ticket and reserved show seat are different

A normal aquarium ticket covers the Night Aquarium; advance electronic tickets can reduce time at the entrance. Advertising: travelers can check Marine World admission on Asoview. A front reserved seat for the dolphin and sea-lion show is a separate product and does not include admission; confirm the live sales page and show schedule rather than relying on an old release date.

Plan the return trip before entering

The nearest rail stop is Uminonakamichi Station on the JR Kashii Line. From Hakata, change at Kashii Station. From Tenjin, the subway to Kaizuka, Nishitetsu Kaizuka Line to Wajiro and JR Kashii Line is another route. Ferry access is possible, but evening return options can be limited. Drivers use the Island City exit and should expect queues around the car park and at closing time.

Best timing and evening cautions

Arrive before 18:00 to see both normal and night lighting; entering close to 20:00 leaves limited viewing time.
The official page predicts the heaviest daytime crowd around 11:00-15:00, while summer weekends can also be busy near closing.
Restaurant Reilly lists food last order at 19:45, drinks at 20:15 and closing at 20:30 on night-operation days.
Re-entry is possible with the facility’s hand stamp. Food may be brought in only to the designated show seating area outside show times, not to tank areas.
