Overview

Step into the heart of Kusatsu and discover Osakaya, a traditional ryokan with deep historical roots dating back to the late Edo period. You’ll find it just a minute’s walk from the iconic Yubatake, the symbolic hot water field that defines Kusatsu Onsen. The moment you step through the front entrance, the quiet elegance of a fully Japanese interior surrounds you. Despite being in the middle of the onsen town, you’ll enjoy a tranquil atmosphere that feels far removed from the buzz of the streets.

The inn was founded by Ichirozaemon Nakazawa, who trained under the Osaka merchant Magohachi. Since then, Osakaya has welcomed poets, artists, and travelers seeking the healing waters of Kusatsu. The calligraphy on the inn’s sign was drawn by the haiku poet Hekigoto Kawahigashi during his stay in 1929.

Accommodation

Osakaya features two main room types: Kamiyashiki and Nakayashiki, both designed in the traditional sukiya-zukuri style. These rooms use natural materials, sliding doors, and tatami floors to preserve the charm of old Japan.

The Kamiyashiki rooms offer the most spacious layout, with additional rooms and alcoves that overlook a private garden. You’ll find features like a tea ceremony room, a veranda, and views that change with the seasons.

The Nakayashiki rooms are available in multiple layouts, including 12-tatami spaces for groups or more compact options for couples. All rooms include a private bath, washlet toilet, LCD TV, and tea set.

Dining

Your stay includes a full-course kaiseki dinner, highlighting seasonal ingredients sourced from both across Japan and locally from the Joshu region. You’ll taste delicacies like fresh seafood, garden vegetables, and carefully simmered broths—all presented with traditional elegance. Meals are served hot or cold at just the right timing, allowing you to savor each bite at its best.

In addition to the standard menu, Osakaya also serves a sukiyaki kaiseki course made with premium Joshu beef. Enjoy the marbled cuts cooked tableside with fresh vegetables and rich dipping sauces. Breakfast features a traditional Japanese meal that gently awakens your body with warm rice, grilled fish, and seasonal sides.

If you have allergies or dietary restrictions, contact the ryokan ahead of your visit. The kitchen will make every effort to accommodate your needs.

Onsen and Wellness

Osakaya uses the highly prized Yubatake source, one of the oldest and most famous hot springs in Japan. The inn draws water directly from this natural source without letting the air affect its quality, delivering it straight into the baths at optimal temperature and mineral content.

The Kunshi-no-Yu, for men, offers an indoor bath made of black granite and a cypress open-air bath with views of the surrounding landscape.

The Shiratama-no-Yu, for women, includes a red granite indoor bath, a cypress open-air bath, and a cave-style bath carved into the mountain slope.

For privacy, you can book a family bath—a rock-lined open-air bath nestled into the hillside. This secluded bath feels like a hidden retreat, perfect for meditation and quiet soaking. The bath includes a private shower area and comes stocked with towels and toiletries.

Guests with Tattoos

If you have tattoos, Osakaya does not permit use of the public baths. However, you can enjoy the private family bath, which offers a secluded experience for individuals or small groups.

Facilities

The moment you walk in, the inn’s traditional beam-style architecture welcomes you. Thick wooden beams and white plaster walls create a striking contrast. The lobby and lounge areas include an irori hearth and plenty of seating for quiet moments with tea.

Visit the gallery space on the second floor to view calligraphy, paintings, and literary works from poets and artists who have stayed at the ryokan over the years. You can also browse the souvenir shop for local specialties, including onsen skincare products and homemade sweets.

For dining, Osakaya provides banquet rooms such as Akamatsu-no-Ma and Araragi-no-Ma, which now serve as the main dining spaces. These large Japanese-style halls are perfect for enjoying meals with family or friends.

Activities

You’re perfectly placed to explore Kusatsu Onsen. Walk to the Yubatake in just a minute, especially beautiful when lit up at night. Slip on a yukata and join the festive atmosphere, especially during events like the summer Edo Wind Chime Festival or the annual Kusatsu Onsen Thanksgiving Festival. Afterward, return to your peaceful room and let the quiet interior wash over you.
