The 79th Kisarazu Port Festival Fireworks Festival — large-bloom star mines dye the night sky with the Nakano-shima Ohashi Bridge in the background
The Kisarazu Port Festival Fireworks, held on August 15, 2026 (7:05–8:30 p.m.), forms the second night of a port festival running since 1948 and reaches its 79th edition this year. About 14,000 shells rise over the inner harbor near Nakanoshima Park, a ten-minute walk from JR Kisarazu Station. The previous evening, the Yassai Mossai dance fills Fujimi-dori, wrapping the whole city in festival mood across two days.
With roots in honoring the pioneers who built this port town, the festival fireworks have grown into Kisarazu's largest annual event. Shells are launched from pontoons inside the harbor, so large rounds bloom close to the water's surface — with the illuminated Nakanoshima Ohashi bridge making the scene unmistakably Kisarazu. Viewing centers on Nakanoshima Park, within walking distance of Kisarazu Station's west exit. Parking is available but public transport is recommended, and since launches begin right at dusk, secure a spot while there is still light. Pairing the visit with the previous night's Yassai Mossai dance parade on Fujimi-dori is a popular way to enjoy the full festival.
