Yume Iroha
熱海温泉ホテル 夢いろは
Private onsen baths and a courtyard spring for steaming food
Day Use
YesDay-use bathing in the main bath runs 13:00 to 22:00. The two private open-air baths have a separate day-use window, 15:00 to 21:00, booked by phone on the day itself, and it's worth confirming by phone in advance since day-use bathing isn't offered every day or every season.
The day-use rate for the main bath is 1,000 yen for bathing only; a bath and face towel set is an extra 500 yen. The private open-air baths have their own day-use rate, 2,650 yen for one person or 2,000 yen per person for two or more, for a 45-minute slot. Day-use visitors cannot use the hotel's parking lot.

About
Yume Iroha is a small hotel in Atami with separate indoor communal baths for men and women, filled with hot, distinctly salty spring water. Two reservable private open-air baths, Yume-no-yu (夢の湯) and Tsuki-no-yu (月の湯), were added in 2021 and share the same water, booked in 45-minute slots for a quieter soak away from the main bath. A few of the guest rooms have their own private open-air bath as well. The inner courtyard holds its own small spring, Aoyama-yu (青山湯), and the steam rising from it is piped through a vent that guests can use to steam eggs, chimaki, and other snacks, bought at the front desk or brought in from outside, an unusual sight even for a hot-spring town like Atami. Steam drifts past the windows too, giving the rooms a proper onsen feel, and the beach is a five-minute walk away.
