Are you planning to send the new year's greeting cards?

In Japan, Sending the New year's greeting card is more popular than Christmas card.

There is a Japanese custom which you'd better know when you send the new year's greeting card.
Person whose relative died in this year will send out the cards to let their friends know that
he(or she) is in mourning. That also means that he is not going to celebrate new year.

So if you recieved the card, you should not send the new year's greeting card to him.
Instead of new year's greeting card, you can send him a season's greetings card to show your sympathy.
