Gamagori Festival Summer Fireworks 2026 Confirmed

蒲郡まつり納涼花火大会 — Gamagori, Aichi (Tokai)

Gamagori's summer festival fireworks are built around one object: the Pacific coast's largest shell, a full sanshakudama (90cm) that climbs 600 meters and blooms 650 meters wide over Mikawa Bay, its light doubling on the water around Takeshima island's shrine causeway. The rest of the 5,000-shell program is a warm-up for those few seconds.

Background

The Gamagori Festival has closed with bay fireworks since the postwar years, and the city made the sanshakudama its trademark — an unusually large shell for a mid-sized festival, possible only because it launches over open sea.

Getting there

The venue is the Takeshima pier waterfront, under 10 minutes on foot from JR Gamagori Station (Tokaido Line, about 40 minutes from Nagoya).

Tips

• The sanshakudama fires late in the program — the crowd audibly counts it down; do not leave early.
• Its burst is so wide that the best 'seats' are actually mid-distance; right under the launch you can't fit it in your vision (or camera).
• Station-to-venue is the shortest walk of any major Japanese fireworks event, which makes same-evening return to Nagoya easy.
• Pair it with a daytime walk across the causeway to Takeshima's island shrine.
