Which Hotels in Lake Toya Offer Private Onsen?

Lake Toya’s private onsen options fall into two main categories: in-room baths attached to specific room categories, and rentable family/private baths that require a reservation and often incur a separate fee. Based on verified property details, four hotels stand out for their private onsen offerings.

Hotel Name Private Onsen Type Lake View Guest Rating Starting Price Per Night

Editor’s tip: If you prioritise a guaranteed private onsen in your room without extra booking, WE Hotel Toya and Tsuruga Resort are your best bets. For a mix of in-room luxury and rentable baths with a classic lake view, Nonokaze is the top pick.

Hotels with private open-air baths

Nonokaze’s “Western-style Rooms or Japanese/Western-style Rooms with Scenic View Baths (Nonokaze Club)” and “Deluxe Rooms with Lake View Baths” come with private hot spring baths, according to Selected Onsen Ryokan. Tsuruga Resort’s dedicated open-air rooms let guests soak in a hot spring while viewing the natural scenery, as stated on the official website.

Hotels with in-room onsen

WE Hotel Toya takes the concept furthest: all guest rooms have hot-water open-air spa baths, effectively making every room a private onsen suite. The same source notes that the rooms have “beautiful views of the scenery of Lake Toya” (Selected Onsen Ryokan).

Best for segments

  • Couples seeking romance: Nonokaze’s rentable private baths face the lake with an unblocked view, and reviewers on TripAdvisor describe the experience as “very romantic”.
  • Families needing space: Toya Kanko Hotel’s private family bath combines an indoor and outdoor onsen with two plunge pools, suitable for around six people (Pasangan Traveling).
  • Budget-conscious travelers: Toya Kanko Hotel starts at around USD 108 per night, and its private bath can be booked even if you’re not staying overnight.
  • Onsen enthusiasts: WE Hotel Toya offers a private bath in every room, allowing multiple soaks per day without reservation.

Our Pick: The Lake View Toya Nonokaze Resort

For couples, luxury seekers, and first-time visitors to Hokkaido, Nonokaze delivers the most complete private onsen experience: a choice of in-room baths in higher-tier rooms, two rentable private baths with lake views, and a 9.0/10 guest rating. The 50-minute sessions are bookable from 16:00 to 23:00, and the checked-in/out times (15:00–19:00 / 11:00) are standard for a ryokan. Where’s Janice calls it the top pick for a “classic Lake Toya experience”.

Lake Toya vs. Noboribetsu: Which Is Better for an Overnight Stay?

Both areas have private onsen hotels, but they differ in atmosphere and logistics. Lake Toya centres on a caldera lake with boat cruises and a quieter, more scenic feel. Noboribetsu is known for its dramatic Jigokudani (Hell Valley) and a larger concentration of onsen ryokan, including some with private baths.

Atmosphere and attractions

Lake Toya’s main draw is the lake itself – you can take a boat ride, watch the evening fireworks (summer), and enjoy the caldera views. Noboribetsu offers geothermal wonders and a more compact onsen town. A 2024 travel guide on Pasangan Traveling notes that Lake Toya feels more relaxed and spread out, while Noboribetsu is more bustling.

Private onsen availability

Both areas have hotels with private onsen, but Lake Toya’s options are more lake-view-oriented. Noboribetsu offers a wider range of private baths in larger ryokan, but the views are typically of gardens or mountains rather than a lake. For a day trip, either is feasible; for an overnight stay, Lake Toya’s sunset and morning calm on the water give it an edge.

Important detail: Tattoo policies in private onsen at Lake Toya appear more flexible than in public baths. A 2024 traveler report states that Toya Kanko Hotel’s private onsen had no specific tattoo regulations for guests booking exclusive use (Pasangan Traveling). Always confirm directly with the property.

Alternatives in the set

If you’re weighing options beyond Lake Toya, Lake Shikotsu is another caldera lake in Hokkaido with onsen hotels, though private onsen availability is less documented. For a purely private onsen experience, Lake Toya’s mix of in-room and rentable baths is more clearly defined.

“We just come to the receptionist and say that we want to use the private bath, then they will prepare the bath for us.”

The bottom line: “We just come to the receptionist and say that we want to use the private bath, then they will prepare the bath for us.”

How Much Does a Private Onsen at Lake Toya Cost?

Private onsen costs vary by hotel and format. Nonokaze’s room rates typically range from 16,400–31,900 JPY per person with dinner and breakfast, and some rooms cost 30,000–50,000 JPY per night depending on the season (Maikoya). The rentable private bath at Nonokaze charges about 4,400 JPY for 50 minutes (Trip.com).

Toya Kanko Hotel offers a more budget-friendly entry point, with rooms starting around USD 108 per night. Its private family bath is available to both guests and day visitors, with separate pricing tiers. A 2024 TripAdvisor review for Nonokaze noted that a bookable private bath session cost roughly AUD 35 for 50 minutes.

Price note: All prices are approximate and dynamic. Check the hotel’s official site or a booking platform for current rates. The starting prices listed here are based on last-available data (2024–2026).

Factors affecting price

  • Room type: in-room private onsen upgrades command higher nightly rates.
  • Season: peak foliage (October) and summer fireworks season see the highest prices.
  • Reservation timing: booking direct may offer meal-inclusive packages that change the effective cost.

What Makes Lake Toya Special?

Lake Toya is a caldera lake formed by volcanic activity, known for its clear waters and the iconic island of Nakajima in the centre. It’s part of the Shikotsu-Toya National Park and offers boat cruises, hiking trails, and year-round hot springs.

Natural features

The lake does not freeze in winter, so onsen views remain open all year. The surrounding Mount Usu and Mount Showa-Shinzan add a volcanic backdrop. A 2024 guide on Where’s Janice describes the area as “a classic Lake Toya experience” that combines onsen with dramatic scenery.

Activities and boat rides

Boat rides on the lake are a popular activity, with sightseeing cruises departing from the Toyako Onsen pier. The lake also hosts evening fireworks from late April to October. For visitors staying at a private onsen hotel, the combination of a soak followed by a boat ride is a common itinerary.

“The rooms have beautiful views of the scenery of Lake Toya.”

Frequently Asked Questions

Do you wear clothes in a private onsen?

No — bathers are expected to enter the onsen naked, as is standard in Japan. Private onsen offer more privacy, but the etiquette remains the same. Some hotels provide a small towel for modesty while moving between the changing area and the bath.

Can I swim in Lake Toya?

Swimming is not permitted in Lake Toya. The lake is designated for boat cruises and scenic viewing, not recreational swimming. The water temperature is cold year-round due to the caldera’s depth.

Are there bears around Lake Toya?

Brown bears inhabit the surrounding forests, but sightings near the onsen town are rare. Hotels in the area do not report bear encounters on their premises. Visitors hiking in the national park should follow usual bear safety protocols.

Is there a boat ride available on Lake Toya?

Yes — sightseeing cruises operate from the Toyako Onsen pier. The most popular option is a 30-minute round trip to Nakajima island. During summer, the lake also features evening fireworks viewed from the boats.

Can Lake Toya be a day trip?

Yes, especially from Noboribetsu (40 minutes by car) or Sapporo (2 hours by bus). If you are staying at a hotel with a private onsen, day-use of the bath may be possible at some properties, such as Toya Kanko Hotel, which allows non-guests to book its private family bath.

Are Lake Shikotsu and Lake Toya the same?

No — they are two separate caldera lakes in Hokkaido, about 90 km apart. Lake Shikotsu is deeper and clearer, while Lake Toya is more developed for tourism, with more onsen hotels and boat services.

What does Toya mean in Japanese?

The name “Toya” ( ) comes from the Ainu language, meaning “lake of the shore” or “shore lake”. It references the lake’s shape and the surrounding landscape.

The bottom line: The name “Toya” ( ) comes from the Ainu language, meaning “lake of the shore” or “shore lake”. It references the lake’s shape and the surrounding landscape.
