Atami Tamanoyu Hotel  

Perched above Sagami Bay in Atami, this family-friendly hot spring hotel sits a walkable 25 minutes from Atami Station and close to attractions like the MOA Museum of Art, Akao Herb and Rose Garden, and Atami Plum Garden.

Rooms show wide sea-and-sky views from large windows and come with a flat-screen TV, air conditioning, refrigerator, bathrobe and slippers. The vibe mixes classic onsen tradition with lively family-friendly energy — expect open-air baths, a public hot spring poured from the source, and a colorful aquarium in the bathing area.

Wake up to sea-breeze mornings and soak in the open-air bath that overlooks the bay. Onsite highlights include hot spring baths, sauna, Neyu (shallow lying bath), a spa and massage room, karaoke, ping-pong/table tennis, a diving club and children’s playrooms. There’s also a bar, a lounge and shops for essentials.

Free Wi‑Fi throughout the property, room service and baggage storage make short work of travel logistics. An elevator provides accessibility to upper floors and paid parking is available on site.

Grab a drink at the hotel bar or relax in the lounge. For local flavors, nearby restaurants include Atami tempura spots such as Ryotei Kuroshio within easy reach.
