, which can be used by 1 to 6 guests. There are also Japanese-style tatami rooms on the mountain side and on the lower floors, as well as a 7.5-tatami Japanese-style room without its own bath, where guests use the communal bath. Some rooms in the annex look out over the parking area or the garden, or have no view; none of them are served by an elevator, so getting to them involves stairs.
Dining
Dinner is a Japanese, Western and Chinese buffet with a 90-minute dining time. Breakfast is also buffet-style, with a 60-minute dining time. Alcoholic drinks are all-you-can-drink at dinner, and soft drinks are free at both breakfast and dinner. À la carte extras such as domestic wagyu steak and abalone grilled in butter can also be ordered.
Baths and Onsen
The hot spring gushes from the property's own source, a rarity in the Boso area. The spring water is a metasilicic acid chloride spring, so it warms you from the core. In addition to the onsen communal bath and sauna, the open-air bath attached to the communal bath is also fed by the hot spring. There is a private-hire open-air bath as well, decorated with precious stones and sago palms, which costs 1,000 yen per group for 45 minutes (tax included) and can be reserved at the front desk. Note that the private-hire open-air bath is not an onsen; its water is heated. Guests are also asked to refrain from mixed bathing with children age 7 and over.
Family-Friendly Features
The hotel is very popular with families traveling with children and with senior guests. In summer there is an outdoor pool that includes a pool for children under school age, and there is a children's pool as well, so families can enjoy it with peace of mind. Because children age 7 and over are asked to refrain from mixed bathing in the onsen communal bath, the private-hire open-air bath, available for a fee, is an option for parents who want to bathe together with a child of a different gender.
