Overview

Ishihanaumi Bettei Kagiya brings you into the quiet mountain side of Minamiizu, away from the busier beach resorts and closer to the old hot spring rhythm of Shimogamo Onsen. You arrive at a pure Japanese-style ryokan surrounded by greenery, open sky, and the soft steam of a hot spring area with more than 400 years of history.

This is a stay for slow meals, long baths, and peaceful time indoors. You walk barefoot across tatami floors, soak in salty source-fed water, enjoy seafood from the Izu coast, and let the day move without pressure. If you want a ryokan that feels calm, local, and rooted in hot spring culture, Kagiya gives you that feeling from the moment you step inside.

Accommodation

You can choose from 10 room types, with 20 rooms in total. Eight rooms include private open-air baths, giving you your own source-fed hot spring space whenever you want to soak. Other rooms offer Japanese-style layouts, bed-style rooms, or larger tatami spaces, so you can choose the atmosphere that fits your stay.

The most spacious open-air bath rooms include the Kihinshi room, with 12.5 tatami mats, a 7.5-tatami adjoining room, and the ryokan’s only room bath with a footbath. The Tokubetsushitsu room has two connected Japanese-style spaces, giving you more room to stretch out and settle in. The Japanese-modern bedroom type places two semi-double beds in a 10-tatami Japanese room, while the open-air bath Japanese room gives you a classic 10-tatami layout with a private bath.

Rooms include thoughtful basics such as towels, yukata, green tea set, tea sweets, television, air conditioning and heating, refrigerator, telephone, safe, toothbrush, razor, hair cap, hair ties, and hairbrush. Free high-speed Wi-Fi is available, and all rooms have internet-connected televisions, so you can watch YouTube, Netflix, Amazon Prime, and other streaming services during your stay.

Dining

Dinner at Kagiya is built around Izu’s seafood and seasonal ingredients. The kitchen prepares kappo-style Japanese cuisine, with each dish arranged carefully so the meal feels both local and refined. You can expect seafood from the waters around Izu, seasonal vegetables, and dishes that show the character of southern Izu without making the meal feel too formal.

Kinmedai is one of the highlights. You may enjoy it simmered in a rich, slightly sweet sauce, served as shabu-shabu with ponzu, or prepared as sashimi depending on the plan and season. Other Izu flavors may include fried kasago, abalone, Ise ebi spiny lobster, and fresh seafood sourced with help from local fishermen. Menus can change depending on ingredient availability, which keeps the meal connected to the season.

Meals are served in the dining area. Private dining rooms are also available with some plans or by arrangement, allowing you to enjoy dinner in a quieter setting. The latest dinner start time is 7:00 PM, so it is best to arrive in time to settle in before your meal.

Breakfast follows the ryokan style, with a Japanese meal that prepares you gently for the day. After breakfast, you can return to the bath, sit in the lounge, or head out to explore Minamiizu.

Onsen and Wellness

The hot spring is the heart of Kagiya. The ryokan uses Shimogamo Onsen, a salty chloride spring with a history of more than 400 years. The water is 100% free-flowing from the source and is not circulated, allowing you to enjoy the strength and warmth of the spring in a direct way.

You can soak in the gender-separated large baths and open-air baths. The bathing spaces have wide windows and a comfortable sense of openness, while the open-air baths let you feel the outside air as the hot spring warms your body. Bathing hours for the large baths are 3:00 PM to 11:30 PM and 6:00 AM to 9:30 AM.

The spring quality is a salt spring, chloride spring, and sodium spring. It is known for its warming effect and is associated with relief from concerns such as neuralgia, muscle pain, joint pain, lower back pain, sensitivity to cold, cuts, burns, and skin care.

If you want more privacy, you can reserve one of the 2 private baths. Each private bath also uses source-fed hot spring water and can be reserved for 50 minutes during evening hours. Rooms with private open-air baths give you the most freedom, letting you soak in your own space at night, in the early morning, or between meals.

For deeper relaxation, you can book treatments in the esthetic room “Komorebi.” Treatments include aromatherapy, facial care, and reflexology, with advance reservations recommended.

Guests with tattoos

Rooms with private open-air baths and the reservable private baths give you more private bathing options.

Facilities

Kagiya has a warm, tatami-lined interior where you can remove your shoes and move through the ryokan barefoot. The entrance has a heavy wooden door with a key-and-lock motif, a detail that connects to the name Kagiya. Just inside, the lobby lounge “Kagi no Chaya” gives you a comfortable place to pause, with drinks available so you can ease into the stay.

The ryokan also has a private dining room area, a larger banquet dining space, a souvenir shop, vending machines, large public baths, open-air baths, private baths, an esthetic room, and meeting spaces that can be used for groups, training, or work-related stays. The shop carries Izu sweets, local products, selected small goods, and handmade-style tableware. Some barrier-free support is available, including wheelchair access in parts of the building, rental wheelchairs, and Western-style toilets in rooms.

Activities

Minamiizu gives you plenty to enjoy before and after your hot spring time. Hirizo Beach is about 20 minutes away by car and is known for its clear water during the summer season. Cape Irozaki, Ryugu Sea Cave, Yumigahama Beach, Ai-Ai Cape, Shimoda Aquarium, and Irozaki Ocean Park are also within easy driving distance.

Spring brings cherry blossoms and rapeseed flowers, while summer draws you toward the coast. On quieter days, you can keep things simple: take a drive, walk near the sea, return for a bath, and let dinner become the main event of the evening.

Kagiya also works well for a workation stay. Each room has free high-speed Wi-Fi, and some rooms have large 65-inch internet-connected televisions that can support remote meetings. You can work in a quiet setting, then refresh with hot spring bathing and seasonal Izu cuisine.
