[*Only the event dates have been updated to 2026. Details for scheduled events will be updated as they are confirmed.] A fireworks festival held at 'Kagamigaura,' the nickname for the calm waters off Tateyama City, Chiba Prefecture. The beauty of the fireworks reflected on the mirror-like water surface is truly exceptional. Underwater fireworks launched from the sea surface, now a signature feature of the event, brilliantly color the summer night sky.
