Overview

Stay in Isawa Onsen, where vineyards, peach orchards, and mountain scenery surround one of Yamanashi’s best-known hot spring towns. Hotel Kimiyoshi places you within the Kofu Basin, with views toward Mount Fuji and the Southern Alps when the weather is clear.

Isawa Onsen began in 1961, when hot water rose from a vineyard and flowed into the nearby river. Today, you can enjoy its smooth alkaline water in spacious indoor and open-air baths. Seasonal Japanese food, Yamanashi wine, and easy access to fruit farms and wineries bring the character of the region into your stay.

Accommodation

Hotel Kimiyoshi has 40 rooms across four main categories. You can choose a Japanese room with tatami and futon bedding, a detached Japanese room with more space, a Western Twin Room, or a Japanese room with a private open-air bath.

The Main Building Japanese Rooms come in eight-tatami and 12.5-tatami layouts. These rooms give you a classic setting where you can sit close to the floor during the day and sleep on futons at night.

The detached Japanese rooms are generally larger, with many offering at least ten tatami mats. They work well when you want more room to stretch out and enjoy a quieter position away from the main accommodation area.

Western Twin Rooms give you two beds when you prefer a familiar sleeping arrangement. For greater privacy, you can choose one of seven Japanese rooms with an open-air bath. The private bath uses heated regular water rather than natural hot spring water.

When the sky is clear, selected rooms offer distant views of Mount Fuji or the Southern Alps. Your room includes free Wi-Fi, a refrigerator, safety box, yukata, towels, toothbrushes, shampoo, conditioner, body wash, razors, combs, and hairbrushes.

Dining

Dinner combines a seasonal Japanese set meal with a half buffet of around 40 Japanese, Western, and Chinese dishes. The Japanese courses are created by a head chef recognised as a Yamanashi Master Craftsman, with ingredients and presentation changing throughout the year.

At the buffet, you can choose popular dishes such as sushi and freshly prepared tempura alongside salads, rice, soup, hot dishes, and desserts. The 90-minute dinner also includes free-flowing drinks such as beer, sake, shochu, soft drinks, and wine produced in Yamanashi.

Breakfast is served as a buffet with around 50 dishes. You can begin the morning with Japanese and Western choices, then enjoy complimentary coffee, juice, and other soft drinks. Breakfast is normally served from 7:00 AM to 9:00 AM.

Onsen and Wellness

The shared bathing area includes a spacious indoor bath and an open-air bath. Both use natural Isawa Onsen water and open from 3:00 PM to midnight and again from 5:00 AM to 10:00 AM.

The spring is classified as a simple alkaline hot spring. Its smooth texture helps remove oils and impurities from the surface of your skin, which has given Isawa Onsen a reputation for skin-friendly bathing.

The water is associated with relief from fatigue, neuralgia, muscle pain, stiff shoulders, bruises, sprains, and reduced movement after physical activity. You can warm up indoors before moving to the open-air bath, where fresh air adds another layer of relaxation.

There is no private natural hot spring bath. The open-air baths attached to selected rooms use heated regular water.

Guests with Tattoos

You cannot use the shared indoor or open-air hot spring baths if you have tattoos.

You can bathe privately when you reserve a Japanese room with its own open-air bath. This private bath uses heated regular water rather than natural hot spring water.

Facilities

Hotel Kimiyoshi includes a spacious lobby, a shop selling souvenirs, a courtyard pond with koi, a yukata corner, a game area, free Wi-Fi, vending facilities, and complimentary parking. You can choose your preferred yukata pattern and wear it while relaxing inside the hotel.

You can also reserve a private karaoke room or a table-tennis session after arrival. Both facilities operate at scheduled times, giving you an enjoyable way to spend the afternoon or evening between meals and hot spring baths.

A complimentary shuttle connects the hotel with Isawa Onsen Station. Afternoon collection is available after you arrive at the station, while scheduled departures run from the hotel in the morning.

Activities

Explore Yamanashi’s wine culture at nearby producers such as Monde Winery, where you can taste local wine and browse regional products. Isawa Onsen Station also has a wine server featuring bottles from wineries in Fuefuki, as well as a public footbath outside the station.

During fruit season, you can visit nearby farms for peach and grape picking. The surrounding orchards become especially colourful in spring, when peach blossoms spread across the Kofu Basin.

For history, visit Takeda Shrine, dedicated to the famous warlord Takeda Shingen, or explore Kai Zenkoji and Erinji Temple. You can also discover Yamanashi’s landscape at Oshino Hakkai, Lake Yamanaka, or FUJIYAMA Twin Terrace, where clear days bring broad views of Mount Fuji.
