Rakuten Travel rating 4.28 out of 5 (2,278 reviews). From a family's point of view, guests praise how well equipped the hotel is, with the pool, the children's play areas and space to move around, and they rate the buffet's wide variety. Some also value being able to stay with children who have not yet started elementary school free of charge. On the other hand, some families felt rushed by the time limits on meals, an hour and a half in the evening and an hour at breakfast.

Overview
Isawa Onsen Hotel Fuji is an onsen resort in Isawa Onsen with six kinds of onsen baths on site, among them Shingen, a large rock bath that is one of the largest in Yamanashi Prefecture, and Kinsui, a large garden bath. Guest rooms range from 10- to 12-tatami Japanese-style tatami rooms in the main building and Japanese-Western rooms pairing a 6-tatami tatami area with three low beds, to the Japanese-style tatami rooms of the Bettei Miho annex and special rooms with a view bath or a balcony. Dinner centers on a creative buffet, with children's chairs and tableware on hand and a kids' corner as well. The playroom on the 1st floor of the main building is only for children of elementary school age and younger, and in summer the outdoor pool opens with a Chibikko Pool for little ones.
Rooms
Standard rooms in the main building are 10- to 12-tatami Japanese-style tatami rooms for 1 to 5 guests, with a bathtub or a shower booth, a toilet with a washing function, a refrigerator and a tea set. The renovated 14.5-tatami Japanese-style tatami room in the main building has a retro-tiled bathroom and sleeps 2 to 6, with room to spare for families and groups. The main building's Japanese-Western room pairs a 6-tatami tatami area with a bed space laid out with three low beds; because the beds sit low, it is an easy room to consider if you worry about a small child rolling out. There are also Japanese-style tatami rooms in the Bettei Miho annex (for 2 to 5 guests) and special rooms with a view bath or a balcony. The Miho Top-Floor Special Room is an 80 sq m Fours (4-person) room for 1 to 4 guests, with a view bath and two bedrooms holding one king-size bed and two semi-double beds. Check-in and checkout times differ by room: 3 p.m. and 10 a.m. for the main building's Japanese-style tatami rooms, and 2 p.m. and 11 a.m. for the Bettei Miho annex and the main building's Western-style and special rooms. A humidifier is available to borrow.
Dining
Dinner and breakfast both center on the buffet at Dining Hestia on the 1st floor. On the buffet plans, dinner is a creative buffet prepared with care by the executive chef; your meal runs for 90 minutes from your start time, and start times are assigned in order of arrival. The Koshu Shunsai kaiseki plan uses a dining area with partitions. The buffet venue is fully stocked with children's chairs, tableware, cups and cutlery, and the kids' corner is lined with dishes for children. Buffet carts for carrying food are provided too, which makes it easier to serve food while keeping an eye on your child. The kaiseki plan includes meals for children as well. Nothing is stated about accommodating allergies, so please confirm with the hotel if you need it.
Baths and Onsen
The spring water is an alkaline simple onsen. Of the two communal baths, the large rock bath Shingen has the open-air bath Furin attached, and the large garden bath Kinsui has the open-air bath Juju. They are open from 2 p.m. to 1 a.m. and from 3 a.m. to 10 a.m., and are unavailable from 1 a.m. to 3 a.m. for cleaning and for switching the men's and women's baths. The changing rooms have a baby bed, a baby bath, baby lotion and baby soap. Mixed bathing for children aged 7 and over is prohibited under Yamanashi Prefecture regulations, so to bathe together as a family you use either a private-hire view bath, which costs extra, or a bath in your room. The private-hire view bath Yururi is 4,400 yen for one 45-minute session and Burari is 3,850 yen for one 45-minute session; both run for 45 minutes from the top of each hour between 3 p.m. and midnight, and can be reserved by phone in advance or requested on the day. The tubs are big enough for about three adults, with washing stations for three. Yururi has a roomier changing area, with a baby chair and a baby bed there as well. Whether a child in diapers may get into the tub is not stated, so please confirm with the hotel.
