Overview

Ishinoya Izu Nagaoka feels like a private village built around stone, water, and quiet Japanese design. The ryokan sits within a 6,612-square-meter Japanese garden, where stones gathered from across Japan shape the atmosphere from the moment you arrive. With only 22 rooms arranged in sukiya-zukuri style, the stay feels calm, spacious, and deeply connected to traditional architecture.

You can walk past stone paths, pause beside the footbath, read in the book café, or return to your room for a private soak. The buildings keep the character of sukiya design from around 50 years ago, with original materials preserved as much as possible. Some details may feel different from a newer hotel, but that is part of the charm: wood, tatami, stone, and natural textures create a stay with real ryokan character.

Accommodation

Ishinoya Izu Nagaoka has 22 rooms, all with a bath and toilet, and all rooms include hot spring water. The rooms follow sukiya-zukuri design, with detached-style layouts, tatami spaces, natural materials, soft scents, quality bedding, and amenities chosen to support deep rest. The atmosphere is private and calm, with many rooms looking toward the Japanese garden.

The first-floor suites offer the most open bathing experience. You can choose a suite with a hinoki cypress open-air bath, a stone open-air bath, or a hinoki open-air bath with a sauna. These rooms include beds and futon bedding, giving you both Western-style sleep comfort and the feel of a Japanese room. The hinoki baths bring a gentle wood fragrance to your soak, while the stone baths create a stronger sense of classic onsen atmosphere. The open-air baths on the first floor use hot spring water with added water and heating in a circulation system, while the indoor baths can draw hot spring water directly from the source.

The Japanese-style suite on the first floor gives you two spacious tatami rooms and a hinoki half-open-air bath. This room is ideal when you want a more traditional ryokan setting, with a broad tatami layout and a garden-facing feel. On the second and third floors, semi-suite rooms combine twin beds with tatami areas and in-room hot spring baths. The second-floor superior rooms offer a more compact stay with a king bed, tatami space, and a private in-room hot spring bath.

In your room, you have practical and thoughtful comforts such as free Wi-Fi, a safety box, refrigerator, kettle, air purifier, hair dryer, and a 55-inch TV with Blu-ray and DVD player. Room amenities include face and bath towels, samue roomwear, bathrobe, shampoo, conditioner, body soap, cleanser, face wash, lotion, milky lotion, toothbrush, razor, hairbrush, hair elastic, cotton swabs, cotton, and hand soap. Many rooms also include a Yogibo cushion, making it easy to stretch out after a bath.

Dining

Dining at Ishinoya Izu Nagaoka brings together seasonal seafood, mountain ingredients, Japanese technique, and creative presentation. Dinner centers on a Japanese creative course meal, with dishes that may include fresh fish from Suruga Bay, Izu wasabi, seasonal vegetables, wagyu, rice from nearby areas, miso soup, pickles, and a final dessert. The menu changes with the season and with ingredient availability, so each stay has its own flavor.

The spring course includes dishes such as yorotofu with salmon roe and wasabi, fresh Suruga Bay sashimi, salt-grilled sea bass with spinach potage, seasonal simmered vegetables, low-temperature roasted wagyu rib roast, eel rice, red miso soup, and monaka with melon, salt butter bean paste, and cream. Breakfast follows a Japanese style, with dishes such as a small hot pot with clams and tofu, local horse mackerel, chasoba with soft-boiled egg, grilled dried horse mackerel or salted mackerel, Gotemba Koshihikari rice, pickles, seaweed, and yogurt.

Meals are served in semi-private dining rooms, so you can enjoy your food in a calm, personal setting without feeling exposed. Dinner is offered in two main seatings, and breakfast is also offered in two main seatings. Special meal additions may include Ise lobster, abalone, Fujiyama wagyu sirloin steak, shabu-shabu, sashimi set meals, sushi, or eel dishes, depending on availability and advance arrangement. Standard dining-room meals are not served in your room, except for special plans, though certain à la carte items and delivery-style dishes may be enjoyed in your room.

Onsen and Wellness

The hot spring experience is one of Ishinoya Izu Nagaoka’s strongest features. Every room has a private hot spring bath, so you can enjoy Izu Nagaoka Onsen at your own pace without leaving your room. The in-room private bath is available 24 hours, making it easy to bathe before sleep, after waking, or whenever the mood feels right.

The spring water is an alkaline simple hot spring, classified as hypotonic, alkaline, and high-temperature. Izu Nagaoka Onsen is known as “Bijin no Yu,” or “beauty water,” and the soft feel of the water makes each soak especially pleasant. In the upper-floor rooms and indoor in-room baths, natural hot spring water can flow directly from the source. The first-floor open-air baths give you a private outdoor bathing space with either hinoki or stone styling, and the mosquito netting helps keep insects out while still allowing you to enjoy the view from inside.

The public bath area includes both indoor and open-air baths. During the day, the open-air area gives you a view of Mount Katsuragi, while evening bathing brings a quieter atmosphere beneath the night sky. The men’s and women’s baths change daily, so you can experience two bath styles during your stay. The public baths are open from 15:00 to 24:00 and from 6:00 to 11:00.

The garden footbath gives you another way to enjoy the hot spring water without changing into bathing clothes. You can sit beside the 6,612-square-meter Japanese garden, warm your feet, and take a slower pause between meals, reading, or a walk through the property. Near the footbath, you can also try the hot spring drinking faucet, which is the only place at the ryokan where you can drink the spring water.

Guests with Tattoos

Ishinoya Izu Nagaoka has shared public indoor and open-air hot spring baths, so tattoos should remain fully covered in these shared bathing areas. If your tattoo cannot be fully covered, please use the private hot spring bath in your room instead. Every room includes a private hot spring bath, so you can still enjoy the onsen experience comfortably and privately.

Facilities

Ishinoya Izu Nagaoka includes 22 rooms, public indoor and open-air baths, a restaurant, meeting rooms, a book café, parking, free Wi-Fi throughout the property, and an AED in the lobby. The book café is a quiet place to read, relax with coffee, and browse selected books. The shop area offers Ishinoya original items and local Izu products, giving you an easy way to bring home a small reminder of your stay.

The public bath area includes towels, shampoo, conditioner, body soap, face and hand wash, hair dryers, hairbrushes, cotton swabs, cotton, and toothbrushes. The men’s bath area also includes shaving foam, hair styling products, lotion, and razors, while the women’s bath area includes face wash, lotion, makeup remover, milky lotion, and hair elastics. You can choose a yukata at the front desk, and samue is prepared in your room.

The ryokan does not have an elevator, so you should choose your room with stairs in mind. All rooms are non-smoking, and smoking areas are available inside the property. You can use the beverage vending machine near the lobby at any time. Useful items available to borrow include selected books, Blu-ray and DVD titles, card and board games, yoga mats, massage goods, facial steamers, sewing sets, irons, trouser presses, high-seat chairs, bead cushions, and body pillows.

Activities

Ishinoya Izu Nagaoka gives you small pleasures inside the ryokan and easy access to Izu’s history, nature, and outdoor experiences. Within the garden, you can join the Ishinoya Heart Hunt, searching for four heart-shaped stones hidden around the grounds. After finding and photographing them, you can show the images at the front desk and receive a sweet treat.

Around the area, you can visit Nirayama Reverberatory Furnace, a UNESCO World Heritage site connected to Japan’s industrial history, or head to Izu Panorama Park for wide views from the mountaintop area. Shuzenji Temple and Ganjojuin Temple add a deeper cultural side to your trip, while Izu-Mito Sea Paradise, Ema Strawberry Picking Center, Nakaizu Winery Chateau T.S, and Izu Ohito Country Club give you more ways to spend the day.

Seasonal and guided experiences may include tea picking with a tea factory visit, a tour connected to Nirayama Reverberatory Furnace and the tea fields, river kayaking on the Kano River with Mount Fuji views, a winery visit with lunch and tasting, sea kayaking or SUP in Suruga Bay with a sashimi lunch, diving or snorkeling at Osezaki, and fruit picking experiences such as mango, blueberry, or strawberry, depending on the season. Many activities require advance reservation and may depend on weather, season, and availability.
