Overview
Atami Heartpia stands on high ground in Atami's Izusan Onsen, with sweeping views over Sagami Bay. The hotel is proud of its onsen, fed generously from 2 spring sources of its own, and alongside the communal bath and open-air bath there is a private-hire family bath. Some Japanese-style tatami rooms come with 2 beds and a shower booth, and the sea-side tatami rooms take from 1 to 6 guests. Co-sleeping is free for children aged 0 to 2, and rates are set according to whether a child under school age has meals and bedding, making this an easy place to stay with young 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 smoking is possible in the smoking room on the 5th floor. The standard Japanese-style tatami room is 25 sq m, or 10.5 tatami mats, for 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 for 1 to 2 guests. The sea-side tatami rooms are sized to match the number of guests in your party, taking 1 to 6 guests. On the top floor, the 7th, there are also Japanese-Western rooms (special rooms) with their own open-air bath, described as well suited to larger families and groups.
Dining
Breakfast is a buffet of about 40 Japanese and Western dishes, served in the 6th-floor restaurant Shiki from 7 a.m. to 9 a.m., with last entry at 8:30 a.m. Dinner is a kaiseki course; depending on the plan, the main dish is either abalone steamed in sake or Japanese beef grilled on a ceramic plate.

Consultations about food allergies are accepted up to 5 days before your stay; contact the hotel by phone or email, and menu changes to suit your needs will be arranged at the hotel's discretion.
Baths and Onsen
The hotel owns 2 spring sources at Izusan Onsen, so the communal bath and open-air bath are supplied generously with onsen water. The communal bath also has a lie-down bath, a jet bath and a low-temperature sauna. 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 you need to bring the towels and bath towels from your room. The private-hire family bath is fed straight from the source and is available by reservation at 2,200 yen including tax for 45 minutes per session - a good choice when you want to bathe with your child without worrying about other guests.
Family-Friendly Features
Alongside the children's rates and co-sleeping arrangements, the route from the guest rooms to the lobby and restaurant has few steps, and staff can help with getting around the shared areas. The 4th floor has 3 karaoke rooms in various 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 with a space where children can play safely, open from 11 a.m. to 4 p.m. Because the hotel is about 10 minutes by car from Atami Station, there are no convenience stores nearby, and there is no walk-in restaurant on the property, so if you choose a plan without dinner it is recommended that you eat before check-in or bring food with you.
