When you are invited to a wedding ceremony, it is common that you bring some gift money (say, 1~3 man yen. The amount i depends on your social status or relation), and the couple prepare return gift for the guests in advance. This custom is applied to other important events including funeral ceremony.

It is also practiced after receiving extravagant hospitality or expensive gift. In such cases, the best return gift item would be not expensive, but something uncommon like one from your country.

Japanese people place importance on the sincere mind of people and balance.
