Originally established in the Edo Period (1603-1868), this vibrant mid-August event now attracts around 500,000 spectators and over 20,000 active participants.

Earning the popular nickname mizu-kake matsuri (water-throwing festival), its signature tradition features crowds splashing buckets of refreshing water onto carriers bearing ornate, gold-and-gem-adorned portable shrines as they parade through the streets near Kiyosumi Garden and Kiba Park.

Beyond the energetic processions, visitors can savor classic Japanese festival food at the many vendor stalls filling the shrine grounds and surrounding neighborhood streets throughout the five-day event.

4. Sumida River Lantern Floating Ceremony (August 15)

The Sumida River Lantern Floating Ceremony brings a magical glow to Asakusa.

Held during the mid-August Obon season, a time when Japanese families remember their ancestors, this moving evening ceremony sees thousands of candle-lit paper lanterns released onto the Sumida River to gently guide the spirits of departed loved ones.

The event gives both residents and international visitors a chance to participate directly. Attendees can purchase a paper lantern to personalize with drawn illustrations, written wishes, or messages of remembrance before staff light the candle and launch it onto the water.

As hundreds of soft, warm lights drift slowly downstream against the night sky, with the illuminated Tokyo Skytree soaring in the background, it creates an extraordinarily tranquil, storybook scene you won't soon forget.
