Overview
Atami Heartpia stands on high ground in Izusan Onsen, Atami, with sweeping views across Sagami Bay. Its pride is a generous supply of onsen water from its own 2 spring sources, and alongside the communal bath and open-air bath there is a private-hire family bath. Some Japanese-style tatami rooms have 2 beds and a shower booth, and the sea-side tatami rooms take 1 to 6 guests. Co-sleeping is free for ages 0 to 2, and rates for children under school age are set according to whether meals and bedding are included, which makes it an easy stay for families with small children.
Rooms
There are 54 rooms: 12 Western-style rooms, 37 Japanese-style tatami rooms, 3 Japanese-Western rooms and 2 Japanese-Western rooms with an open-air bath. All rooms are non-smoking, and guests who smoke can use the smoking room on the 5th floor. The standard Japanese-style tatami room is 25 sq m (10.5 tatami mats) and sleeps 1 to 2 guests; it has 2 beds and a shower booth and was renovated in 2026. The Western-style twin room is 30 sq m and sleeps 1 to 2 guests. The sea-side tatami rooms are sized to suit the number of guests and take 1 to 6 people. On the top floor, the 7th, there are also Japanese-Western rooms (special rooms) with their own open-air bath, which the hotel presents as well suited to larger families and groups.
Dining
Breakfast is a buffet of about 40 Japanese and Western dishes, served at the 6th-floor restaurant Shiki from 7 a.m. to 9 a.m. (last entry 8:30 a.m.). Dinner is a kaiseki course, and depending on the plan, the main dish is either abalone steamed in sake or Japanese-raised beef grilled on a ceramic plate. Children's rates are set by age: junior high school students and older pay the adult rate, elementary school children pay 70% of the adult rate, and children who have not yet started elementary school pay 50% of the adult rate. Up to 2 children can co-sleep. Co-sleeping is free for ages 0 to 2, while other children under school age are charged a facility fee of 1,000 yen before tax. Food allergy consultations are accepted up to 5 days before your stay. Contact the hotel by phone or email, and the menu will be adjusted to your needs at the hotel's discretion.
Baths and Onsen
The hotel owns 2 spring sources in Izusan Onsen, so the communal bath and open-air bath enjoy a generous supply of onsen water. The communal bath also has a lie-down bath, a jet bath and a low-temperature sauna, among other features. The spring water is a simple onsen (hypotonic, weakly alkaline, high-temperature), and bathing hours are 11 a.m. to midnight and 5:30 a.m. to 9 a.m. the next morning. No towels or bath towels are provided at the communal bath, so bring the ones from your room. The private-hire family bath is fed straight from the source and can be reserved for 2,200 yen including tax per 45-minute session. Compared with the communal bath, it is a good choice when you want to bathe with your child without worrying about other guests.
Family-Friendly Features
Besides the children's rates and co-sleeping options, the route from the guest rooms to the lobby and restaurant has few steps, and staff can help you get around the shared areas. The 4th floor has 3 karaoke rooms of different sizes, from a room for a large group to a small room a family can enjoy together. Next to the 5th-floor communal bath there is a free lounge that includes a space where children can play safely, open from 11 a.m. to 4 p.m. The hotel is about 10 minutes by car from Atami Station, so there are no convenience stores nearby, and there is no restaurant on the property that takes walk-in guests. If you choose a plan without dinner, it is recommended that you eat before check-in or bring your own food.
