I bought New Year's greeting cards at the post office yesterday.
On the message side, a rabbit that is the next year's oriental zodiac animal is depicted, and on the other side that the recipient's address and name should be written, you can see the lottery numbers.
The draw takes place in mid-January. If you have a card(or cards)with winning numbers, you will get an equivalent article to the rank of your lottery number.
However, in Japan, there is a practice that you don't send and receive New Year cards if some one in your family died during the year. In that case, you send your friends a postcard between November and early December to notice you are in mourning.
