Lake Toya is a caldera lake formed by a volcanic eruption 100,000 years ago, with an active volcano (Mt. Usu) on its southern shore that last erupted in 2000. The combination of a perfectly round lake, volcanic scenery, natural hot springs, and a small onsen town makes it one of the most complete day trips from Sapporo — or a worthwhile overnight if you want to soak in the hot springs and catch the evening fireworks.

The lake sits roughly halfway between Sapporo and Hakodate, making it a natural stop on the drive between the two cities. Combined with nearby Noboribetsu (30 minutes away), you can cover two of Hokkaido’s top onsen destinations in a single trip.
What to See
Mt. Usu Ropeway
A cable car to the summit of Mt. Usu (737m), one of the most active volcanoes in Japan. The ropeway takes 6 minutes and deposits you at an observation deck with views across Lake Toya, the volcanic crater, and on clear days, the Pacific Ocean and Mount Yotei (the “Hokkaido Fuji”). From the deck, a 20-minute walking trail leads to a closer viewpoint of the 2000 eruption crater — you can see steaming vents, collapsed ground, and buildings half-buried by the eruption.
The eruption trail is fascinating and sobering. Houses and roads destroyed just 24 years ago are preserved as they were found, giving a real sense of the volcano’s power. Entry: approximately 1,800 yen (includes ropeway round trip).
Toyako Onsen Town
A small hot spring town on the lake’s south shore. The main street has hotels, souvenir shops, and foot baths (free). The town is compact and walkable — you can cover the main area in 30 minutes on foot. The lakeside promenade has sculptures and views across to the central island.
From April through October, fireworks launch from boats on the lake every night at 20:45. The display lasts 20 minutes and is visible from the lakefront promenade and most hotel rooms facing the lake. Free, no crowds (weeknight displays often have more empty bench seats than occupied ones), and genuinely impressive for a nightly show.
Showa Shinzan
A volcanic dome that literally did not exist before 1943. During World War II, earthquakes and eruptions pushed this 400-metre lava dome out of flat farmland over the course of two years. A local postmaster, Mimatsu Masao, documented the entire process in detailed sketches — one of the most complete records of volcanic dome formation ever made. The Mimatsu Museum near the base tells this story.
Showa Shinzan is adjacent to the Mt. Usu Ropeway base station. See both in one visit.
Lake Cruise
Sightseeing boats cross the lake to Nakajima (the central island), which has a nature walk and forest trail. The cruise takes about 50 minutes for the full circuit. The island is pleasant but not essential — the real value of the cruise is the view of the caldera from the water. Cost: approximately 1,500 yen.
Hot Springs
Toyako Onsen town has natural hot springs piped to all the lakeside hotels. The main draw for overnight visitors is the outdoor baths (rotenburo) at the hotels, many of which overlook the lake. Soaking in hot spring water while watching fireworks launch from boats on the lake is one of those experiences that sounds like a travel brochure cliche but actually delivers.
Day-use bathing is available at several hotels for 500-1,500 yen if you are not staying overnight.
Getting There
- From Sapporo (by car): approximately 2 hours via expressway. The most flexible option, especially combined with Noboribetsu.
- From Sapporo (by train): JR to Toya Station (1 hour 50 minutes by limited express), then bus to Toyako Onsen (20 minutes). Covered by the JR Hokkaido Rail Pass.
- Day tour from Sapporo: Book on Klook (from approximately $39, includes Noboribetsu).
- From Hakodate: approximately 2.5 hours by car. A natural stop between the two cities.
Day Trip or Overnight?
Day trip: works if you are driving. Cover Mt. Usu ropeway, lakeside walk, lunch, and optional Noboribetsu in a full day from Sapporo. You miss the fireworks and the onsen soak.
Overnight (recommended): arrive by afternoon, take the ropeway, walk the town, soak in the hotel onsen, watch fireworks from the lakefront, sleep. The onsen hotels are the main reason to stay — the experience of an evening lake-view bath is worth the extra night.
