40th Anniversary 2026 Lake Biwa Great Fireworks Festival — Colorful large blooms fill the lake surface and night sky (C) Biwako Visitors Bureau
Lake Biwa Great Fireworks Festival lights up the waters off Otsu Port in Shiga Prefecture on August 6, 2026 — the 40th edition since its 1984 debut. Marking the anniversary, the show adopts a two-part structure for the first time: part one pairs drone shows, lasers and music-synced fireworks, while part two brings back staples such as diagonally fired shakudama. Around 12,000 shells bloom over the lake surface.
Few fireworks venues match the scale of a whole lake. Launched from the waters off the prefectural Otsu Port area, roughly 12,000 shells rise between 7:30 and 8:30 p.m. on August 6, 2026, their light doubled by the reflection on Lake Biwa. The 40th-anniversary program splits into two parts — a modern first half of drone shows, laser beams and music-synced sequences, followed by classics like the diagonally fired shakudama. Reach the venue on foot in 15 minutes from JR Otsu Station or 5 minutes from Keihan's Biwako-Hamaotsu Station. Traffic restrictions apply nearby and there is no parking, so come by train and expect lakeside paths to be busy.
