Hello from Kamonoya, operator of 11 whole-house lodging properties in Lake Toya, Hokkaido. When you picture winter at Lake Toya, you might imagine snow-view open-air baths and quiet lakeside scenery. But as locals who run inns here, what we most want you to experience is the winter night at Lake Toya Onsen. Some 400,000 illumination bulbs, winter fireworks bursting over the lake, and a community snow festival—when snow and light blend together, the onsen town at night shows a completely different face from daytime. In this article, we focus on the winter night events, sharing the highlights, how to tour them, and how to stay warm.
For daytime winter activities (snow play, hot springs, sightseeing), see our separate article, Winter at Lake Toya. This guide is dedicated to the evening events.
Winter Nights at Lake Toya Onsen: Light and Fireworks Take Center Stage
Lake Toya Onsen is a compact, walkable district on the lake’s southern shore, where hot-spring inns, souvenir shops, and restaurants cluster together. In winter the sun sets early, and darkness falls around 5 p.m. That very darkness is what makes Lake Toya’s winter nights so beautiful: light spreads softly across the reflecting snow, and fireworks mirrored on the lake create a magical scene.
There are four main winter-night events: the year-round Illumination Street, the winter-season centerpiece Illumination Tunnel, the February Lake Toya Onsen Winter Fireworks, and the community Toya Snow Festival. All are within walking distance of the onsen town or a short drive away, so you can combine them easily using your lodging as a base.
Illumination Tunnel: A 70-Meter Tunnel of Light with 400,000 Bulbs
The single biggest highlight of the winter night is the Lake Toya Onsen Illumination Tunnel. The venue is “Nigiwai Hiroba” (Nigiwai Square) in the onsen town, across from Toyako Manseikaku Hotel Lakeside Terrace. A roughly 70-meter tunnel of light decorated with some 400,000 LED bulbs, along with a dome about 9 meters in diameter, appears amid the snowscape for you to walk through.
The lighting period and hours for the 2025-26 season are as follows.
- Period: November 1, 2025 (Sat) – April 27, 2026 (Mon)
- Hours: November 1, 2025 – February 28, 2026: 17:00–22:00 / March 1 – April 27, 2026: 18:00–22:00
- Location: Nigiwai Square (Lake Toya Onsen town)
Walking through a tunnel of light on a snowy night, wrapped in glow underfoot and all around, makes for wonderful photos. As long as you dress warmly, it is easy enough that even families with small children can enjoy it in a short visit. It is a walkable distance from your lodging, so you can drop by before or after dinner.
*Lighting period and hours are as of July 2026. Details vary by year, so please confirm the latest information on the Lake Toya Onsen Tourism Association official site.
Illumination Street: Year-Round Lakeside Light with 12,000 Bulbs
Pair the tunnel with the Illumination Street. Roughly 12,000 illumination bulbs decorate the street that runs from the onsen town down to the Lake Toya shore. This one is lit year-round, from sunset until around 10 p.m., so you can enjoy it in any season, not just winter.
Our recommended evening route is to stroll along the lakeside bathed in light, then continue straight to the Illumination Tunnel. In winter the pavement is often frozen or snow-covered, so non-slip winter boots will let you walk with confidence.

Lake Toya Onsen Winter Fireworks: Music Fireworks Coloring the Winter Sky
Lake Toya is famous for its “Lake Toya Long-Run Fireworks,” held nightly from late April through the end of October—but did you know that fireworks also rise in winter? The Lake Toya Onsen Winter Fireworks is a special event where fireworks synchronized to music light up the clear winter night sky and the snow-dusted lakeshore.
The 2026 event overview is as follows.
- Period: February 3 (Tue) – February 12 (Thu), 2026, over 10 days
- Time: nightly from 20:30, about 8 minutes (canceled in severe weather)
- Launch site: the pier in front of Toya Lake Steamship head office (about a 10-minute walk from Lake Toya Onsen Bus Terminal)
- Admission: free for general viewing (paid special viewing booths, limited to 40 people per day)
These are sustainable, Lake Toya-style fireworks: “eco fireworks” made with biodegradable materials, with carbon offsetting through geothermal power. Fireworks seen in the crisp winter air have a vividness distinct from summer. Including the light mirrored on the lake surface, you can enjoy scenery unique to this season.
For fireworks at Lake Toya in general (the summer long-run fireworks and viewing spots), see our Lake Toya Fireworks Guide as well.

Toya Snow Festival: A Snow Event to Enjoy with the Community
Another distinctly wintry event is the Toya Snow Festival. Held around early February each year at the Fureai Square near Toya Mizu-no-Eki (Toya Water Station), it is a community festival with treasure hunts, true-or-false quizzes, candy tosses, a giant snow slide, and other activities the whole family can enjoy. Warm and community-focused rather than aimed at tourists, it lets you feel the local winter atmosphere.
Because it is held a little away from the Lake Toya Onsen town, traveling by car is convenient. Limited-run events like the snow festival and winter fireworks change dates from year to year. When planning your trip, also check our Lake Toya Annual Events.

Staying Warm: Tips for Enjoying Winter Nights
Winter nights at Lake Toya frequently drop below freezing. Since fireworks and illuminations mean standing outdoors for a while, solid cold-weather preparation is the key to enjoying them comfortably.
- A thick down jacket plus layers: standing still to watch gets colder than you expect. Layering you can adjust underneath is ideal.
- Non-slip winter boots: the pavement is often frozen or snow-covered, and ordinary sneakers are slippery and unsafe.
- Gloves, a knit hat, and a scarf: keeping your extremities warm greatly changes how cold you feel. Disposable hand warmers help too.
- A hot drink: warm yourself between viewings.

Base Your Winter Nights at a Warm Private Rental
To make the most of the illuminations and winter fireworks, it helps to have a place nearby where you can head straight back and warm up when you get cold. Kamonoya’s properties are all whole-house or whole-unit private rentals with a kitchen and bath. From a property in the heart of the onsen town, you can walk to the Illumination Tunnel and Illumination Street, and on fireworks nights enjoy the luxury of “watch, then return to a warm room for a breather.”
For example, Toya House in the center of the onsen town, and Lake Toya Building, an apartment-style unit near the lakeshore and onsen town, make ideal bases for an evening of event strolling. Because they are private rentals, families with small children and groups can enjoy the winter night at their own pace, without worrying about other guests. See the list of properties for the features of each.
If you would like to prepare dinner at your lodging, cooking with local ingredients is a great option; see our Lake Toya Gourmet Guide.

Frequently Asked Questions
Q. When can I see the illuminations?
The Illumination Tunnel (Nigiwai Square) is typically lit from early November to late April the following year. For the 2025-26 season it runs November 1, 2025 to April 27, 2026, with hours of either 17:00–22:00 or 18:00–22:00 depending on the period. The Illumination Street is lit year-round, from sunset until around 10 p.m. Details vary by year, so please confirm on the official site.
Q. Are the winter fireworks held every day?
The Lake Toya Onsen Winter Fireworks are a limited-run event. In 2026 they run over 10 days from February 3 to 12, launched nightly from 20:30 for about 8 minutes (canceled in severe weather). This is separate from the nightly summer long-run fireworks, so it is best to check the dates before planning your itinerary.
Q. Can families with small children enjoy the evening events?
Yes. The illuminations can be enjoyed even in a short visit, and since they are within walking distance of the onsen town, you can head back to your lodging as soon as you get cold. Kamonoya’s properties all have a bath and kitchen and are private rentals, so you can warm up and go at your children’s pace. Just be sure to prepare well for the cold.
Q. How do I get around on winter nights? Is a car essential?
The Illumination Tunnel, Illumination Street, and winter fireworks are all within walking distance of the onsen town (within about a 10-minute walk from the bus terminal), so if you stay in the onsen town you can enjoy them without a car. However, events held away from the onsen town, such as the Toya Snow Festival, are more convenient by car. If you are not used to driving on winter roads, don’t push yourself—we recommend planning mainly around the walkable events centered on the onsen town.
