Full-day tour from Tokyo or Atami: Sea Fireworks Festival
Last updated: August 26, 2026
Watch the Atami Sea Fireworks Festival from a chartered boat out in the bay — a full-day tour from Tokyo ending in a cascade of light over the water. Two routes share the same evening: one climbs Mount Omuro, the grass-covered volcanic crater above Ito often cited as the inspiration for the meteor scenes in Your Name; the other pairs vermilion Hakone Shrine on Lake Ashi with the Showa-retro storefronts of Atami Ginza and a free evening for dinner in town. Atami's fireworks burst over a bay ringed by mountains that hold and echo every report, and from the boat's private deck they open directly overhead before the coach carries you back to Shinjuku.

Frequently Asked Questions
Unlike most Japanese fireworks, Atami's are not a single summer night: the city stages its sea fireworks on scheduled dates through the whole year, with the summer series the busiest. That makes this one of the few fireworks experiences you can plan a trip around in any season.
The shore venue draws enormous crowds, while the chartered boat waits out in Atami Bay itself — the shells burst practically overhead, the mountains around the bay throw the sound back like an amphitheater, and you watch from open water with room to breathe.
The Mount Omuro route spends the afternoon on the bald volcanic crater above Ito, with views across Izu and toward Mount Fuji from the rim. The Hakone Shrine route visits the lakeside torii and cedar-lined approach on Lake Ashi, then gives you Atami Ginza's retro shopping street and a free evening for dinner before the fireworks.
It departs from the Mode Gakuen Cocoon Tower beside Shinjuku Station and drops you near Shinjuku's west exit late in the evening — check the return time against your last train, as fireworks nights run late.
