10 Popular Hotels in Kusatsu for Solo Travel

Kusatsu Onsen is a mountain hot spring town in Gunma Prefecture, around three hours north of Tokyo by train and bus. Compared to other onsen towns, Kusatsu produces an unusually large volume of naturally acidic mineral water, which is said to cure nearly any illness and has shaped daily life here for centuries. Instead of being tucked away or hidden underground, the water flows openly through the center of town, giving Kusatsu a sense of place that feels active and alive.

At the heart of it all is Yubatake (hot water field), where steaming water cools as it passes through wooden channels before being distributed to local baths. The surrounding streets are compact and walkable, making Kusatsu particularly well-suited to solo travel. Most experiences here are designed for one, such as wandering the streets between bathhouses, soaking for hours on end, and enjoying a quiet meal alone in your ryokan (traditional Japanese inn) suite. These 10 hotels are especially popular with solo travelers looking for comfort, privacy, and easy access to the heart of town.

Kusatsu Onsen Sen is a small, adults-only inn that suits solo travelers who want privacy and a quieter atmosphere without being far from the action. The walk to Yubatake takes under 10 minutes, making evening strolls easy. With just 15 rooms and several reservable private onsen baths, it’s simple to soak without worrying about timing or crowds. The hot spring water is drawn directly from a local mineral source, and you can enjoy a kamameshi (rice dish in iron pot) breakfast, which keeps mornings low-effort. 

Kusatsu Onsen Naraya combines history with a modern sense of calm, making it a comfortable choice for solo stays. Located close to Yubatake, the inn draws from one of Kusatsu’s oldest spring sources. Rooms blend Japanese and Western design, creating a relaxed but modern feel. There’s an on-site café and bar for light evenings, while the in-house restaurant serves refined kaiseki (seasonal cuisine) meals in the dining spaces.

For solo travelers who value space and privacy, Kusatsu Onsen Yubatake Sensui stands out for its generously sized Western-style rooms. Each room includes a private open-air hot spring bath, allowing you to soak whenever it suits you. The on-site hot pot restaurant is convenient if you don’t feel like heading out at night, and the overall setup works well for travelers who want independence with minimal shared facilities.

Set slightly above the main hot spring town, Kusatsu Onsen Ryokan Tokinoniwa offers a peaceful retreat-like atmosphere. Every room features its own open-air onsen bath, which makes it especially appealing for solo guests who prefer private bathing. The elevated position gives the property a more secluded feel, while still being close enough to Kusatsu’s central sights for easy exploration during the day.

For those who prefer to live more like a local than a tourist, Kusatsu Onsen Gensen Ichinoyu has you covered. Rooms here are larger, making them ideal for longer stays, with many equipped with kitchenettes and private onsen baths, allowing you to cook your own food and bathe on your own schedule. The on-site lounge and bar provide a relaxed place to unwind in the evening, and the architecture blends naturally with Kusatsu’s streetscape, helping the stay feel grounded and local rather than resort-like.

Easy to spot thanks to the large tanuki (raccoon dog) figure at the entrance, Kusatsu Onsen Tajimaya Ryokan has a friendly, old-town charm that works well for solo travelers. The baths use natural hot spring water sourced from Yubatake, and the atmosphere feels closer to a bed-and-breakfast than a formal ryokan. It’s a good choice if you want something welcoming, low-key, and centrally located.

Just a couple of minutes from Yubatake, Kusatsu Onsen Yubatake no Yado Yoshinoya is a casually styled inn that is practical and forgiving for solo itineraries. Late-night check-in is available, which is helpful if you arrive after dinner or travel in from Tokyo in the evening. The relaxing indoor baths and breakfast service make the experience feel stress-free, especially for first-time visitors to Kusatsu.

As one of Kusatsu’s long-established inns, Kusatsu Onsen Nisshinkan has a strong connection to the town’s hot spring culture. It’s particularly known for wellness-oriented stays, making it a good option if your solo trip is focused on rest and recovery. There’s also an adjoining café that specializes in Japanese-style desserts, offering an easy, comfortable place to spend a quiet afternoon alone.

Kusatsu Onsen Kusatsu Hotel 1913 is a long-established wooden hotel that maintains its traditional appeal even with recent updates, including a renovated open-air bath area and a modern restaurant. The historic structure gives the stay a sense of place, while the refreshed facilities ensure comfort. For solo travelers, it offers a balanced experience: rooted in Kusatsu’s past but equipped for contemporary travel expectations.

Minshuku Hyotan is a good fit for solo travelers who enjoy a more personal, home-style stay. A private bath is available around the clock, using natural hot spring water, and the traditional multi-course dinners are generous without feeling formal. The wooden building adds warmth and character, while English-speaking staff and easy access to Yubatake keep things simple and comfortable.
