Ajiro Onsen Marine Fireworks Festival: Fireworks with excellent acoustic effects are launched
The Ajiro Onsen Maritime Fireworks launch 2,000 shells over Ajiro Port in Atami City, Shizuoka, on Sunday, August 16, 2026, from 20:30 for 20 minutes. Lantern floating in nearby Taga Bay lets lights and fireworks mingle on the water, while fish-shaped shells, aerial Niagara cascades and side-launching maritime star mines add variety. Ajiro Station is a 3-minute walk, and with no parking, trains are the way to go.
Organized by the Ajiro Onsen Tourism Association, the maritime display runs 20:30–20:50 on Sunday, August 16, 2026, over the waters of Ajiro Port in Atami City, Shizuoka, drawing about 15,000 visitors with 2,000 shells spreading across the harbor. Lantern floating in nearby Taga Bay is a highlight — the glow on the water and the fireworks' light overlap into one scene. The varied program in a short span includes fish-shaped shells, aerial Niagara cascades and the maritime side-launching star mines fired diagonally from the sea. JR Ajiro Station on the Ito Line is just a 3-minute walk, and with no parking at the venue, arriving by train is the dependable choice; the venue is within walking distance of the onsen district's inns.
