The 140th Mine Festival & Fireworks Festival — Approximately 500 fireworks color the summer night sky
The fireworks finale of the Kozan Festival — one of Sado Island's three great festivals, marking its 140th edition — takes place at Aikawa-hama Park on Sunday, July 26, 2026. From 20:00 to 20:30, about 500 shells centered on star mines rise over the old mining town of Aikawa. The festival also features rituals at Oyazumi Shrine and an okesa dance parade through town, with about 10,000 visitors expected. Cross by ferry and drive about 60 minutes from Ryotsu Port; a temporary lot offers 300 spaces.
The Kozan Festival honors the 'mountain deity' of Aikawa's mines, opening with rituals at Oyamazumi Shrine and livening the town with okesa dance processions. Its finale is this display: about 500 shells, mostly star mines, light the sky for roughly 30 minutes from 20:00 on July 26. The venue, Aikawa-hama Park, sits about 60 minutes by car from Ryotsu Port or 70 minutes from Ogi Port via Route 350 and Prefectural Route 45 — work the ferry crossing times into your itinerary. A temporary lot offers 300 spaces. No paid seating is provided, and viewing from the seaside park is open to all. Food stalls appear on site, so some cash comes in handy.
