Depending on the room type, bed guards or a setup with the beds pushed together may be available; the eligible age starts at 18 months.

Dinner and breakfast are both served buffet-style at the Takimitei restaurant, with a Japanese, Western and Chinese spread (or Japanese and Western) (dinner 5:30 p.m.-8:00 p.m., breakfast 7:00 a.m.-9:00 a.m.). Depending on how busy it is, the schedule may change or service may be divided into 2 or 3 seating periods. If arrival is after 6:00 p.m., dinner time may be shorter or dinner may not be served. When a room has at least 2 adults, children are charged as follows: elementary school-age children, 70% of the adult rate; children under school age with their own bedding, 50%; and children under school age sharing existing bedding, JPY 5,500 including tax. When 1 adult and 1 child stay together, the child is charged the adult rate.

Baths and Onsen

The property has 4 natural spring sources and its own natural hot spring welling up on site. The spring water is an alkaline simple spring (weakly alkaline).
