The Japanese love to give gifts. This habit is not practiced only on special occasions, but it’s widely accepted as social duty and responsibility. Because gift-giving is such an important social aspect of Japanese life. It's important to be aware of some key factors.
Devalue the gifts you give. The important thing is to act and seem modest. You don't
want the receiver to think that you are arrogant or proud. Denigrate(贬低) your gift as much as possible. It doesn't matter if the label on the box bears the symbol for a famous brand. The Japanese value the appearance of a modest gift-giver who tries to stay away from praise.
Praise the gift you receive. Although praising may seem obvious, overpraising the gift is the key. It's also important to praise the fine taste of the gift-giver in making that particular choice for you. And don't forget to give a thousand and one thanks.
unless you are urged to do so. And when you do, you must take the utmost care in unwrapping it. Don't look eager, and be careful that you don't tear the paper or cut the ribbon. After observing, praising, and thanking, be sure to rewrap the gift as if it had never been opened. Try to appear as if you take great pride in the value of the gift.
Choose gifts with practical value. In general, don't buy things such as ornaments, vases, and kitchenware; it's already assumed that everyone has these things. To do so may suggest that you don't approve of the other person's taste. Also, most Japanese houses are very small and don't have extra space for useless junk.
