I don't know now, but I think there were people who had a pillow fight（Makura nage,枕投げ,まくら投げ） after the teacher returned to the room after bedtime on the school trip（Shugaku ryoko,修学旅行）.
A competition is also held.

First of all, Wikipedia tells me that the American game of Pillow Fighting is different from the Japanese Makura-nage, so I'm going to write about the latter.

Makura-nage is what young students in Japan commonly do when they go on overnight school trips and put into a room of, say, five students or more. It's almost like a ritual. It's, of course, forbidden, but kids do it anyway. It's so common, that kids with allergy seek help in advance.

Wikipedia also tells me that there are official games of Makura-nage.
