In the case of hotels/ryokan that charge a fee for children or infants, the following age groupings are standard:
Infant: 0-2 years of age
Child: 3-12 years
Adult: 13 years and older
Some hotels/ryokan offer bedding and meals for children, but these are not available for infants. In general, infants are expected to sleep together with their parent(s) or guardian(s).
Typically, children 6 years and older are expected to require separate meals and bedding to be provided by the hotel. The amount of service (i.e., meals, bedding) to be provided is divided into categories as Child A, B, C, and D, which is determined by the hotel.
When making a booking with children, we ask that you accurately indicate the age of your children. For example, if a hotel defines Child A as a 10 year old, you may not register your 10 year old as a younger Child D (no meals or bedding); you will need to pay the price for Child A.
Please note that not properly registering your children when booking may incur additional charges later. In cases where the actual ages and number of guests in your party exceeds the capacity of the room, you may be refused service altogether.
