The Setagaya Firefly Festival and White Egret Flower Market is a family-friendly summer tradition held on Boroichi Street.
What happens?
The most popular event is the chance to see fireflies while walking through a dark, enclosed dome. Be prepared for long lines, and you’ll be asked to keep moving — but it is free to see. There will also be a flower exhibition featuring white egret flowers, a species of orchid that resembles a heron.
Schedule 2025
The event takes place on July 19 and 20. You can enter from 4 p.m., but the firefly viewing will take place from 5 p.m. to 9 p.m. on both days at the Setagaya Daikanyashiki’s parking lot.
