Tokyo Solamachi Summer Festival is scheduled for August 1 to 3

Tokyo Skytree Town says the Tokyo Solamachi Summer Festival will run from Saturday, August 1, through Monday, August 3, 2026, together with the Sumida Ward Citizens' Evening Bon Dance gathering.

According to the official release, the bon dance is free and will be held from 18:00 to 20:00 in Solamachi Plaza on the first floor, under the Skytree. The Summer Festival itself is scheduled for 12:00 to 21:00 across Solamachi Plaza and the first-floor Solamachi Shopping Street, with popular Solamachi shops set to appear as festival stalls.

For visitors, the useful point is that the release already separates the daytime and evening timings, so you can plan whether you want food stalls during the day, the bon dance at night, or both. The notice also says stall hours in Solamachi Plaza may vary by shop, and event details can change, so checking the latest official guidance before going is still the safest plan.
