Can a family with 3 children stay in one room?

With two adults and three children you are five people. Whether one room is enough depends on two numbers the hotel publishes: the room’s maximum guests and the age up to which a child can share a bed without being counted (here: 6 and under at check-in).

Japanese Apartment: Up to 4 adults (age 7+) plus up to 2 children aged 6 or under sharing beds; 4 sleeping places (Single bed x2, Futon x2).

None of the room types listed here takes 5 guests in one booking. If your children are older than the bed-sharing age, count each of them as a guest and make sure the room has a sleeping place for each.
