Overview

Kamenoi Hotel Nagatoro Yorii gives you a highland-style hot spring stay in Yorii, Saitama, with wide views of the Chichibu mountain range, the Arakawa River, and the Chichibu Railway from the upper-floor baths. The hotel reopened after renovation on April 1, 2025, with refreshed rooms, lobby spaces, restaurant areas, and an open-air observation bath.

The renewed design takes inspiration from the Arakawa River that flows through Nagatoro and Yorii. In the lobby, you see details that recall the riverbed and boat culture of Nagatoro, while the restaurant brings in the atmosphere of the Chichibu Festival. The result feels local, open, and easy to enjoy.

You stay around ten minutes by shuttle from Yorii Station and around 15 minutes by car from Hanazono Interchange. This location works well when you want natural hot spring water, mountain views, local Chichibu flavours, and access to Nagatoro’s river scenery without staying in the busiest sightseeing area.

Accommodation

You can choose from rooms with private natural hot spring baths, Western-style rooms, Japanese-Western rooms, Japanese-style rooms, and an accessible room. All rooms are non-smoking and include Wi-Fi.

The Superior Fourth with Natural Hot Spring Open-Air Bath was added with the 2025 renewal. It measures 40 square metres and lets you enjoy the hotel’s pH 9.6 Kanayama Onsen water in your own open-air bath at any time. The Special Japanese-Western Room with Natural Hot Spring Bath measures 44 square metres and also lets you bathe privately in natural hot spring water. This room has two washbasins, making it convenient when you travel with family or friends.

The Superior Fourth without an onsen bath measures 40 square metres and includes a separate bath and toilet. The accessible room measures 44 square metres, with wider corridors and entrances, a flatter layout, handrails around the bath, and space designed for easier movement. The Superior Triple measures 33 square metres and has three beds, a separate bath, and a separate toilet. The renewed Triple Room measures 35 square metres and has two beds plus a daybed, with a unit bath.

The standard Triple Room measures 29 square metres and has two beds, with an additional stacking bed when needed. The Deluxe Twin measures 35 square metres and places two semi-double beds on Ryukyu-style tatami, with futons prepared on the tatami when more sleeping space is needed. The renewed Superior Twin measures 28 square metres and looks towards the mountains, while the renewed Twin Room measures 22 square metres and gives you a compact room with a private bath.

The Japanese-Western Room measures 44 square metres and combines beds with a Japanese-style relaxation area.

Room amenities include yukata, bath towels, towels, toothbrushes, hairdryer, television, refrigerator, in-room safe, bidet toilet, brown haori jacket, cold-water pot, and bath bag. Hairbrushes, hair ties, shower caps, cotton buds, and similar items are available from the front desk when needed.

Dining

Dinner focuses on seasonal kaiseki dishes made with local ingredients from Chichibu, Yorii, and the surrounding Saitama region. The renovated dinner venue takes inspiration from the Chichibu Festival, with a large boat-shaped ceiling and lantern-style lighting. You can enjoy your meal in a setting that connects the food with the culture of the area.

The kitchen uses vegetables from Rikimaru Farm in northern Fukaya, Bushu Sashi Pork, Bushu Wagyu beef, river fish such as char and sweetfish, summer vegetables, Chichibu miso, and regional fermented foods such as oname. Oname is made from barley koji and soybeans and has long been part of daily meals in the Chichibu area.

Seasonal dinner courses may include dishes such as Bushu Wagyu beef sukiyaki, grilled char with miso, wild boar hot pot with Chichibu miso, grilled sweetfish, sashimi, seasonal vegetables, Sayama tea soba, and rice dishes using local flavours. Menus change with the season and ingredient availability, so your meal reflects the time of year.

Breakfast is served as a buffet in a bright restaurant area designed with the feeling of a morning market. The buffet counter recalls the Nagatoro rock beds along the Arakawa River. You can enjoy local vegetables, waraji katsu, sukiyaki made with Saitama-grown bean sprouts and shirataki noodles, Chichibu miso potatoes, konjac somen noodles, vegetable smoothies, rice, and other Japanese and Western breakfast items.

Kamenoi’s late-night dandan noodles are also served in the evening during scheduled hours. The flavour changes by month, and the portion is designed as a light night meal rather than another full dinner. At breakfast, the sea bream Kamenoi-zuke with grated yam gives you another signature dish to enjoy over rice.

Food allergies should be shared before your stay. Some menus can be adjusted, but ingredients in seasonings may be difficult to remove, buffet items cannot be individually changed, and complete allergen separation cannot be guaranteed.

Onsen and Wellness

The hotel uses Kanayama Onsen, the only natural hot spring in Yorii Town. The water rises from around 1,500 metres underground and is classified as an alkaline simple hot spring with a pH of 9.6. The texture feels smooth and slightly thick on the skin.

The top-floor large public bath gives you views over the Chichibu mountains, the Arakawa River, and the Chichibu Railway. On operating days, you may also see the SL Paleo Express from the bath area. At night, the open-air observation bath gives you a wider view of the sky above the mountains.

The listed bathing qualities include support for chronic muscle and joint discomfort, lower back pain, neuralgia, frozen shoulder, bruises, sprains, and stiffness linked with motor paralysis. The bath is especially rewarding after walking around Nagatoro, riding trains through Chichibu, or spending time outdoors.

Shared bath hours run from early morning and again from late morning until midnight, with a later opening on Tuesdays and Wednesdays. The hotel also has a private bath that uses the same alkaline simple hot spring water and requires a reservation. Rooms with natural hot spring baths let you enjoy Kanayama Onsen privately without using the shared bath.

Guests with Tattoos

You cannot use the shared public baths when your tattoos are visible. Kamenoi Hotel’s public-bath policy allows use only when tattoos are fully covered so they are not visible to others.

You can use the reservable private bath or choose a room with its own natural hot spring bath when you want to bathe privately.

Facilities

The renewed lobby lounge uses the image of the Arakawa riverbed and includes bench seating inspired by festival viewing spaces. Outside, a real wooden boat adds a playful Nagatoro touch. The shop carries Chichibu sake, local souvenirs, Yorii ripe mandarin orange sweets, pickled shakushina, and Chichibu oname.

You can use three non-smoking karaoke rooms, two table tennis tables, the restaurant, breakfast venue, top-floor public baths, reservable private bath, smoking corner, Wi-Fi throughout the building, luggage storage on the day of arrival or departure, and parking. Electric vehicle charging is available through the hotel’s current charging system.

The entire building is non-smoking, with smoking limited to the designated smoking corner. Wi-Fi may be weaker in some parts of the building.

Activities

Nagatoro and Yorii give you easy access to river scenery, seasonal flowers, local food, and Chichibu culture. Nagatoro’s cherry blossoms are one of Japan’s Top 100 Cherry Blossom Viewing Spots, with more than 3,000 cherry trees blooming from late March to late April. Kanaoyama Azalea Park is close to the hotel and has around 5,000 azaleas blooming from mid-April to early May, along with views over the Chichibu mountains and Kanto Plain.

The Nagatoro line descent lets you ride a traditional boat along the Arakawa River, passing rock formations and rapids such as Kotakino Rapids. Hodosan Ropeway takes you towards mountain views, flowers, a small zoo, and seasonal scenery, while SUSABINO Terrace gives you another high viewpoint across the Chichibu mountains.

You can also visit the Saitama Prefecture River Museum, where the Arakawa River becomes the main theme through hands-on exhibits, a large wooden waterwheel, water play, and an adventure theatre. Tsuburata Lake offers hiking and fishing, while Tsuki no Ishi Momiji Park is known for illuminated autumn leaves in mid to late November.

For cultural experiences, Chichibu Nishiki’s Sake Brewing Forest introduces you to a sake brewery founded in 1749, with a museum, shop, and tasting corner. Outdoor activities around Nagatoro include rafting on the Arakawa River, lake SUP, and udon-making experiences. In winter, the Chichibu Night Festival brings floats and fireworks to Chichibu Shrine and is counted among Japan’s major float festivals.
