utsurigami; special paper given in return for a gift
A traditional Japanese custom: when receiving a gift, one gives a sheet of special paper (often decorated) as a token of gratitude. The term is culturally specific and may be unfamiliar even to some modern Japanese speakers.
Since I received a year-end gift, I expressed my thanks with a sheet of utsurigami.
In the old days, it was polite to give back utsurigami when you received a present.
Compound of 移り (utsuri, 'transfer' or 'moving') + 紙 (kami, 'paper'). The exact historical origin is uncertain, but the term likely refers to the paper that 'moves' from the receiver back to the giver as a token of thanks.
