In hotels in Japan, you can often see how much it costs for adults to have two meals in a berth, but how do children charge?

Lz, this different hotel is different One depends on how old the child is. Generally divided into infants, children under 6 years old, primary school students and high school students. Babies are basically free, while some hotels of other ages can be free as long as they don't add beds and meals, and some will charge 30%~80% of the bed fee. It is most reliable to consult in advance when booking a hotel. I wonder if lz can speak Japanese? If so, I suggest you ask the hotel by email. If not, you can find a larger booking company like Ctrip, and they will confirm with the hotel whether it is necessary to increase the money ~
