Lake Toya & Mt. Usu
Caldera Beauty and Living Volcano
Lake Toya formed approximately 110,000 years ago from a massive volcanic eruption that created a caldera 11 kilometers in diameter. The lake's name derives from the Ainu language 'to-ya' meaning 'lakeside cliff.' Four volcanic islands sit in the lake's center, formed by later eruptions. The Ainu people revered the lake as sacred, and archaeological evidence suggests human habitation around its shores for over 10,000 years.
Mount Usu, rising 737 meters on the lake's southern shore, is one of Japan's most active volcanoes, erupting four times in the 20th century alone: 1910, 1943-45 (creating Showa-shinzan, a new mountain), 1977-78, and most recently in 2000. The 2000 eruption prompted the evacuation of 16,000 residents and dramatically altered the landscape. Remarkably, no lives were lost due to excellent volcanic monitoring and emergency response. The eruption sites are now preserved as volcanic science education areas.
Today, Lake Toya and Mt. Usu form a UNESCO Global Geopark, recognized for their geological significance and the community's coexistence with active volcanism. The area demonstrates how humans adapt to and respect powerful natural forces. The Toyako Onsen hot spring resort town thrives on the lake's western shore, while ropeway and walking trails provide safe access to Mt. Usu's still-steaming craters.

Tips & Visiting Guide
Make the most of your visit with these helpful tips and guidelines.
Mt. Usu Ropeway & Crater Walks
The ropeway ascends 502 meters in 6 minutes to observation platforms near Mt. Usu's summit. From the top station, two walking routes explore steaming craters and 2000 eruption sites: Outer Rim Course (60 minutes, moderate) and Summit Course (40 minutes, easier). Stunning 360-degree views encompass Lake Toya, the Pacific Ocean, and on clear days, Mt. Yotei. Wear sturdy shoes and layers - it's significantly cooler and windier at the summit.
Showa-shinzan & Volcanic Museum
Showa-shinzan, a 398-meter mountain that emerged from a wheat field during 1943-45 eruptions, still steams from fissures in its rocky slopes. The adjacent Volcanic Science Museum documents the mountain's birth with seismographs, photographs, and the detailed diary of local postmaster Mimatsu Masao, who recorded the eruption. The combination ticket (museum + ropeway) saves ¥200. Allow 30-45 minutes for the museum.
Lake Cruises & Island Landing
Sightseeing boats depart from Toyako Onsen pier every 30-60 minutes (30-minute circuit, ¥1,500). Some cruises include 15-minute stops at Nakajima Island, where walking trails explore forests and small shrines. The island offers a peaceful retreat with Ezo deer often visible. Evening fireworks cruises (April-October, ¥2,000) combine boat rides with front-row views of nightly pyrotechnics launched from the lake.
Fireworks Display
From late April to late October, 450 fireworks illuminate the lake nightly at 8:45 PM (20-minute show). Two boats move across the lake launching fireworks, visible from any lakeside location. Best viewing spots: Toyako Onsen waterfront promenade, hotel lakeside terraces, or from a boat. The tradition dates back to 1982 and has become the longest-running nightly fireworks event in Japan.
Lakeside Cycling
The flat, paved 36-kilometer lakeside cycling path offers one of Hokkaido's best bike rides with continuous lake and mountain views. Rental shops in Toyako Onsen provide bicycles (¥500/hour, ¥2,000/day). The full circuit takes 3-4 hours at a leisurely pace. Shorter 10-kilometer sections from onsen town to Sairo Observatory (gorgeous views) or Tsukiura Falls make excellent 1-hour rides.
Lakeside Onsen Hotels
Toyako Onsen features numerous hotels with natural hot spring baths overlooking the lake. Luxury options like The Windsor Hotel Toya Resort and Toya Kanko Hotel offer premium experiences. Mid-range choices include Hotel Grand Toya and Toya Kohantei. Many offer day-use bathing (¥1,000-1,500). Lakeside free foot baths provide budget relaxation. Staying overnight allows you to enjoy both lake sunset and morning mist.
Best Photography Locations
Sairo Observatory offers panoramic lake views with Mt. Usu and Showa-shinzan. Sunrise from eastern shore with mountains reflected in glassy water is magical. Nakajima Island provides foreground interest. The illuminated onsen town and fireworks at dusk create stunning nightscapes. Autumn foliage (mid-October) frames the volcanic landscape beautifully. Winter ice formations at lake edges add unique elements.
Year-Round Access & Weather
Lake Toya never freezes due to its depth (180m) and volcanic activity warming the water, enabling year-round boat cruises and water activities. Summer (June-August) is warmest but can be crowded. Autumn (September-October) offers spectacular foliage and comfortable temperatures. Winter (December-March) brings snow-covered landscapes and fewer crowds, though some facilities have reduced hours. Spring (April-May) cherry blossoms bloom along the lakeside.
FAQ
Can I visit both Lake Toya and Mt. Usu in one day?
Yes, both attractions are close together and easily combined in one day. Most visitors take the Mt. Usu ropeway in the morning (2-3 hours including walking trails), then spend the afternoon at Lake Toya enjoying the lakeside or taking a boat cruise. The areas are only 10-15 minutes apart by car or bus.
When was Mt. Usu's last eruption?
Mt. Usu last erupted in 2000, creating new craters and destroying nearby buildings. Before that, eruptions occurred in 1977-78. The volcano remains active with constant monitoring. Visitors can safely explore the area and see remarkably preserved disaster sites showing volcanic power, including buried buildings and newly formed craters.
What can I see from the Mt. Usu ropeway?
The ropeway takes you to a summit platform at 550 meters with panoramic views of Lake Toya, Showa-Shinzan lava dome, the Pacific Ocean, and on clear days, Mt. Yotei. From the upper station, walking trails lead to observation points overlooking active steam vents and volcanic craters.
How long are the walking trails at Mt. Usu?
The outer rim trail takes about 50-60 minutes to complete the loop, offering crater views and steaming vents. A shorter route to the main observation deck takes 15-20 minutes each way. Trails are well-maintained but have stairs and uneven sections. Proper walking shoes are essential.
What is Showa-Shinzan and can I climb it?
Showa-Shinzan is a lava dome that emerged dramatically during the 1943-45 eruptions, growing from flat farmland to 398 meters. Climbing is prohibited due to ongoing volcanic activity and unstable ground. However, you can view it closely from the base and visit the adjacent Showa-Shinzan Bear Ranch.
Are the Lake Toya fireworks year-round?
Yes, Lake Toya is famous for nightly fireworks from late April to October, launching from boats around 8:45-9:00 PM and lasting 20 minutes. Fireworks move along the lakeshore so different hotels get front-row views each night. This is one of Japan's longest-running fireworks events.
What's the best way to enjoy Lake Toya?
Take a sightseeing boat cruise to the central Nakajima Island (30-40 minutes), cycle or walk the lakeside path, rent a kayak or stand-up paddleboard, or simply relax at lakeside onsen hotels. The scenic 43km lakeside road is also popular for driving or cycling with frequent scenic pullouts.
Is the Mt. Usu ropeway affected by weather?
Yes, the ropeway may suspend operations during strong winds, heavy rain, or thunderstorms for safety. Winter snow and ice can make summit trails slippery or closed. Call ahead in questionable weather. On foggy days, views are obscured but the volcanic landscape remains interesting.
Can I see volcanic activity at Mt. Usu?
Yes, you'll see active steam vents (fumaroles) releasing white sulfurous steam throughout the summit area. Some craters have warm ground and strong sulfur smells. While no lava flows actively, the area clearly demonstrates ongoing volcanic processes. It's a safe, accessible way to observe an active volcano.
Where should I stay to see the fireworks?
Lakeside onsen hotels in Toyako Onsen town offer the best fireworks views, many with rooms or outdoor baths facing the lake. Popular choices include The Windsor Hotel Toya, Lake Toya Tsuruga Resort Spa Mizu no Uta, and Toya Kanko Hotel. Book lakeside rooms specifically for fireworks season.
How do I get to Lake Toya from Sapporo?
Highway buses from Sapporo Station to Toyako Onsen take about 2.5 hours and cost around 2,780 yen. By train, take JR to Toya Station then a local bus 20 minutes to the lakeside (total 2-3 hours). Rental car offers most flexibility for exploring both Lake Toya and Mt. Usu.
What is the Eruption Memorial Walk?
A 1.9km walking path showcasing remnants of the 2000 eruption including destroyed buildings, buckled roads, and informative panels explaining the disaster. The walk starts near the ropeway base and takes 40-60 minutes. It's a sobering reminder of volcanic power while demonstrating Japan's disaster preparedness and recovery.
Are there any restaurants with lake views?
Yes, the lakeside promenade has several restaurants and cafes with terraces overlooking Lake Toya. Hotel restaurants often welcome non-guests for lunch with lake views. The Lake Toya sightseeing boat terminal area also has dining options. Local specialties include wakasagi (smelt) and Hokkaido beef.
What's the best season to visit?
Late April through October offers fireworks, pleasant weather, and all facilities open. Autumn (October) provides colorful foliage. Winter (December-March) is quiet with snow-covered scenery and ice formations, but many facilities close and boat cruises don't run. Summer weekends get crowded with domestic tourists.
Can I visit Nakajima Island in the lake?
Yes, sightseeing boats include a 30-minute stop at Nakajima Island with forest walking trails and a small museum. The island is uninhabited and offers peaceful nature walks with lake views. Boats run regularly from late April to early November. Winter service is suspended when parts of the lake freeze.
Is Lake Toya suitable for swimming?
The lake is quite cold even in summer (around 16-20°C) and there are no designated swimming beaches with lifeguards. Some brave locals swim, but most visitors prefer water activities like kayaking, canoeing, or paddleboarding. The lakeside is better suited for scenic enjoyment rather than swimming.
How long should I spend at the Mt. Usu area?
Plan 2-3 hours total: 15 minutes for the ropeway round trip, 1-1.5 hours for summit trails and views, and 30-45 minutes for the Eruption Memorial Walk at the base. Add more time if visiting Showa-Shinzan Bear Ranch or having a meal. This fits well into a day trip combined with Lake Toya activities.
Are there onsen hotels with good volcano views?
The Windsor Hotel Toya, located on a hill above the lake, offers stunning volcano and lake views from rooms and baths. Most lakeside hotels focus on lake views rather than volcano views. For Mt. Usu proximity, stay near the ropeway base, though these hotels are smaller and more basic.
What facilities are at the ropeway summit?
The upper ropeway station has restrooms, a small souvenir shop, and covered viewing areas. No restaurants are at the summit, so eat before ascending or bring snacks. Walking trails are well-marked with safety information in Japanese and English. Emergency shelters exist along trails in case of sudden volcanic activity.
Can I bring children to Mt. Usu summit?
Yes, the ropeway is child-friendly, but summit trails have stairs and uneven ground that may challenge very young children. Strollers are impractical on trails. The sulfur smell can be strong, which some children dislike. The observation deck near the ropeway station requires minimal walking and offers good views for families.
