From Marriott press release re: 5 properties opening in Japan:

"Izu Marriott Hotel Shuzenji is nestled into the densely wooded hills of the Izu Peninsula. Interiors of this 128-room hotel merge contemporary Japanese aesthetic with Western influences, some with private open-air baths. Taste grilled regional Japanese cuisine and international favorites at the restaurant, while the two banquet halls are ideal for meetings and special events. Diverse wellness options include a large communal onsen hot spring, bedrock bath and 24-hour Fitness Center. Guests can also enjoy a large gymnasium, golf & putting range as well as tennis courts."

Noticed this on the website:

"There is a special bath tab in some rooms which is faced to Mt.Fuji and any other mountains."
