A 5th year for a proven format

Sunshine Aquarium in Ikebukuro has opened the 5th edition of its recurring after-dark special exhibit, "Mada Mada Sei Ippai-ten," running September 11 through November 3, 2026. The series, which began in 2019, has drawn roughly 120,000 visitors cumulatively across its first four editions.

Hours for the special exhibit are 18:15 to 21:00, with last entry 30 minutes before closing.

What's actually on display

The exhibit explores animal courtship, reproduction, and parenting through hands-on, interactive displays, with new touch-and-experience content introduced for this year's edition alongside explanatory panels.

What To Know

This is a proven, popular recurring event (roughly 120,000 cumulative visitors across its previous four editions) that gives readers a distinctly different, after-dark reason to visit an aquarium they might otherwise only think of as a daytime destination.

Sunshine Aquarium's night-hours special exhibits are a separate ticketed experience from its regular daytime admission, reflecting a broader pattern among Tokyo attractions of running distinct evening programming to draw a different crowd after dark.
