About this event
The Biwako Visitors Bureau carries the event's official details. The display was long fixed on 8 August, but the 40th edition moved to Thursday 6 August 2026, and the 2027 date had not been announced when checked, so 8 August 2027 is the expected date from the event's tradition. Roughly 350,000 people watch from the Otsu waterfront.
