The nightly signature of Lake Toya Onsen, the “Lake Toya Long-Run Fireworks Festival,” is one of Japan’s longest-running firework displays—held almost every night from late April through the end of October. For roughly half a year, about 20 minutes of fireworks are launched over the lake each evening, making it one of the highlights of any Lake Toya trip. In this article, Kamonoya, a whole-house rental operator based here at Lake Toya Onsen, shares the essentials of the festival, tips for watching, and lodgings that are handy for enjoying the show.

What is the Lake Toya Long-Run Fireworks Festival?
A distinctive feature of the festival is that the fireworks are launched from a boat that moves along the lakeshore off the Lake Toya Onsen town. Because the launch boat travels across the water as it fires, you can enjoy the fireworks from anywhere along the onsen town.
- Season: Typically late April to October 31 (may be cancelled in bad weather)
- Launch time: About 20 minutes from around 20:45 every night
- Launch site: Off the lakeshore of Lake Toya Onsen town (launched while moving)
- Price: Free to watch (paid firework-viewing cruises are also available)
*For the latest dates and times, please check the official announcements of the Lake Toya Onsen Tourism Association.
Recommended ways to watch
1. A relaxed view from the lakeside promenade
The lakeside promenade along the onsen town is the classic spot—the fireworks are visible from anywhere along it. Strolling out to the lake in a yukata after dinner to watch is the Lake Toya way.
2. Up close from a firework-viewing cruise
During the season, firework-viewing cruises operate, letting you experience the launches up close from the water (paid; please check in advance).
3. In private from your own lodging
Stay at a lodging in the heart of Lake Toya Onsen and you can enjoy the fireworks at your own pace, without worrying about crowds. With a whole-house rental in particular, the greatest luxury is being able to wait for each night’s fireworks in a space that is yours alone—family or friends together, with dinner and drinks in hand.
