Daiba News Update, September 2026: Waterfront Festa and Local Events

As of September 11, 2026, one of the most immediate official Daiba updates is Minato City's 20th Mizube Festa, scheduled for September 13 at Odaiba Marine Park. The 2026 event marks both Minato City's 80th anniversary and the festival's 20th edition, with regional boat races involving Shibaura, Konan and Daiba, an anniversary race and stage programs. The city's event information also lists the 30th-anniversary Odaiba Summer Festival at Odaiba Rainbow Park, with a pre-festival from 5 p.m. to 9 p.m. on September 25 and the main event from 1 p.m. to 9 p.m. on September 26. Local community information has also been refreshed recently, including Daiba Children's Hall on August 27 and current Daiba Nursery School updates. Across the wider waterfront subcenter, the Tokyo Metropolitan Government has operated the Tokyo Aqua Symphony waterfront show since March 2026 and introduced a revised summer program in July. Event schedules can change because of weather or operational circumstances, so official announcements should be checked before attending.
