Lake Toya

Hokkaido, Japan · Lake, Mountain, Town / small city

A near-circular caldera lake with an island at its centre and a live volcano on its shore: Mount Usu last erupted in 2000, and you can still walk among buckled roads and wrecked buildings. Below it sits a hot-spring town with fireworks over the water every night from April to October.

The essentials

Getting there

Train + bus — JR Hokuto limited express to Toya Station (about 1h40 from Sapporo, around 2h from Hakodate), then a 15-20 minute Donan bus to Toyako Onsen (roughly hourly); there is also a direct Sapporo-Toyako Onsen bus (about 2h45, reservation required). A car is strongly recommended for circling the lake, Showa Shinzan and the viewpoints, as public transport around the lake is sparse.

Frequently asked questions about Lake Toya

What to do in Lake Toya: 26 activities

• Mount Usu Ropeway 1.5 h must-see Sobetsu · 15 min

  A six-minute ride up Mount Usu with views over the lake and Showa Shinzan, plus, from a second viewpoint a short walk away, the great 1977 crater and the Pacific. ¥2,000 return; runs year-round (with a few weeks' winter maintenance), with the last descent between 16:00 and 17:45 depending on the season.

• Nightly Fireworks (Long Run Hanabi) 0.5 h must-see only 28 Apr - 31 Oct

  From 28 April to 31 October, every night from 20:45 to 21:05, fireworks are launched from a boat on the lake in front of Toyako Onsen. Free from the promenade or your hotel window; they go ahead in rain and are only called off for wind.

• Nishiyama Craters Trail 1.5 h must-see only 20 Apr - 5 Nov

  Free boardwalks among the craters opened by the March 2000 eruption: a national highway heaved up by tens of metres, tilted houses and sunken utility poles, left exactly as they were. Open late April to early November, 9:00-16:00; in winter only with a paid guide. Five minutes by car or about 30 on foot from town.

• Lake Cruise to Nakajima Island 1 h

  Toyako Kisen's castle-shaped boat does a roughly 45-minute loop out to the islands in the middle of the lake, leaving from beside the bus terminal (about ¥1,420). It runs year-round: every 30 minutes from late April to October and hourly in winter.

• Lake-View Onsen Bath 1.5 h

  Several hotels in town open their baths to day visitors: the cheapest is around ¥600 (Hotel Grand Toya), while rooftop baths with lake views such as the Manseikaku's cost ¥1,200-1,500, open 7:00-21:00. If you are staying over, soak before the fireworks.

• Mount Usu Crater Rim Trail 3 h Sobetsu · 15 min only 1 May - 31 Oct

  From the upper ropeway station, some 600 steep steps take you down and back up to the outer crater rim, where the ground still steams and you can see Mount Yotei and Uchiura Bay. Allow about three hours including the ropeway; closed by snow from November to April. Brown bears live here: carry a bell and heed the warnings.

• Showa Shinzan and the Mimatsu Masao Museum 1 h Sobetsu · 15 min

  A reddish volcano that pushed up out of a wheat field between 1943 and 1945 and still steams at the foot of the ropeway. Local postmaster Mimatsu Masao charted its growth in a diagram volcanologists still cite; his small museum opens Friday to Sunday. Climbing to the summit is forbidden except on the museum's own paid guided tours.

• Around the Lake and the Sculpture Park 4 h

  Fifty-eight outdoor sculptures in bronze, marble and steel ring the lake, most of them by the shore. Circling it by bike (about 40 km, almost flat) or by car is the best way to see the lake from every side; bikes are rented in Toyako Onsen. Snow makes it a poor idea in winter.

• Demi-Glace Hamburg Steak at Boyotei 1 h

  A 'yoshoku' Western-style restaurant opened in 1946 in central Toyako Onsen, known for its hamburg steak and pork chop with house demi-glace sauce (about ¥1,750-2,000, rice extra). Lunch 11:00-15:30 and dinner 17:00-20:30; closes irregularly.

• Fireworks-Viewing Boat 1 h only 28 Apr - 31 Oct

  During fireworks season, the Toyako Kisen boat heads out at night so you can watch from the lake, close to the launch boat (about ¥1,600). Bring a jacket: it gets chilly on deck even in summer.

• Fruit Picking in Sobetsu 1.5 h Sobetsu · 15 min only 20 Jun - 31 Oct

  The east shore of the lake is orchard country: cherries in late June and July, grapes in September, and apples and plums in October, at farms such as Sobetsu Kudamono Mura (around ¥1,500 for all you can eat in the orchard). June to October only, and best by car.

• Gelato at Lake Hill Farm 1 h Toyako (Hanawa, orilla oeste) · 15 min

  A dairy farm on a hill above the lake making gelato from its own milk; on clear days you can see Mount Yotei and the Niseko range. Open year-round (9:00-18:00 in high season, until 17:00 in winter); butter-making workshops by reservation.

• Konpira Crater Ruins 1 h only 26 Apr - 10 Nov

  Right above Toyako Onsen, a free trail through what the 2000 mudflows left behind: a bridge torn from its footings and wrecked municipal apartment blocks, preserved as a lesson. A good companion to Nishiyama, walkable from town; closed in winter.

• Lakeside Promenade and Free Foot Baths 1 h

  The lakeside promenade in Toyako Onsen has several free hot-spring foot and hand baths, with sculptures dotted along the shore. Early in the morning the lake is often mirror-still with Mount Yotei behind it.

• Landing and Walking on Nakajima Island 2.5 h only 25 Apr - 15 Nov

  From late April to mid-November the boat lets you off on Nakajima, an uninhabited forested island with a small forest museum. The full loop trail takes several hours, so most people walk a short section; you are very likely to see deer, introduced in the 20th century and now overabundant. Keep an eye on the time of the last boat back.

• Showa Shinzan International Snowball Fighting Championship 3 h Sobetsu · 15 min only one weekend in late February

  Since 1989, seven-player teams in helmets, armed with machine-made snowballs, have competed at the foot of Showa Shinzan under official 'yukigassen' rules. It is held on a weekend in late February (21-22 February in 2026); watching is free and there are food stalls.

• Silo Observatory 0.5 h Toyako (borde oeste de la caldera) · 15 min

  High on the caldera rim by Route 230, the most complete view of the lake, taking in Nakajima, Mount Usu and Showa Shinzan at once. Free to visit; the shop sells sweets and local produce. Only practical by car.

• Visitor Center and Volcano Science Museum 1 h

  In the middle of town, it covers the 1977 and 2000 eruptions of Mount Usu with salvaged objects and a screening room that recreates the shaking. It is the hub of the Toya-Usu UNESCO Global Geopark. The visitor centre is free and the museum costs ¥800; closed on Mondays.

• Wakasaimo and Imoten at the Original Shop 0.5 h

  Wakasaimo, a sweet that mimics roasted sweet potato without containing any (bean paste, sugar and kombu for the texture), has been sold in Toyako Onsen since 1930. At the main shop they fry it in tempura batter to order: 'imoten', about ¥140 a piece, is only found here.

• Winter Fireworks 0.5 h only about ten days in early February

  For about ten days in early February (3-12 February in 2026) the fireworks return, this time set to music, from 20:30. You watch them over the snowy lakeside from the promenade, and they coincide with the town's winter festival.

• Guided Stand-Up Paddleboarding on the Lake 1.5 h booking only 15 Jun - 10 Sep

  90-minute beginner sessions with Toya Guide Center, board and wetsuit included (about ¥13,000 per person, extra for an English-speaking guide). Only from mid-June to early September, when the water allows, and book at least a week ahead.

• Irie and Takasago Jomon Shell Mounds 1 h Toyako (junto a la estación de Toya) · 20 min

  Two shell mounds from roughly 7,000 to 3,000 years ago, part of the Jomon Prehistoric Sites in Northern Japan inscribed as World Heritage in 2021. The small museum is free and 15 minutes' walk from Toya Station: a good stop on arrival or departure. Closed on Mondays.

• Showa Shinzan Bear Park 1 h Sobetsu · 15 min

  Next to the ropeway, dozens of brown bears live in concrete pits while visitors throw them biscuits bought from vending machines; animal-welfare groups criticise facilities like this over space and treatment. If you go, know what you will see; admission around ¥900-1,000, open year-round.

• Toya Summer Festival (Chousa Parade) 2 h Toyako (barrio de Toya, orilla norte) · 25 min only late July

  On the north shore of the lake, a village founded by settlers from Kagawa parades its 'chousa' drum floats, brought from Shikoku, along with a children's procession in late July. It is a small, very local festival, held around the Mizu no Eki lakeside station.

• Usu Zenkoji Temple 1 h Date · 25 min

  One of the three official temples the shogunate founded in Ezo in the early 19th century, on an older place of worship; it is a national historic site and its main hall has survived Mount Usu's eruptions. The grounds are free and known for a rock-splitting cherry tree in spring; the treasure hall is by reservation only.

• Winter Illumination Tunnel 0.5 h only 1 Nov - 27 Apr

  Once the summer fireworks end, the town puts up a tunnel of some 400,000 lights by the lake, from November to late April (17:00-22:00; from March, starting at 18:00). A short, free after-dinner stroll.
