It is time for Christians to exchange Christmas greeting cards.
Here in Japan, we have similar custom to exchange New Year's Cards.
Many Japanese people buy New Year's cards with lottery numbers at the post office, while others buy blank post cards, and print photos or pictures of their own.
As New Year's cards are best to arrive on the New Year's Day, post offices encourage people to post the cards by a certain date every year.
The number of New Year's cards they have to handle is tremendous. Some send only 20-30 cards,and others send as many as some hundred.
In Japan, exchanging New Year's card is often practiced among companies as part of business, too.
December used to be very busy season for Printing houses to print New Year's cards, but recently, more people print their cards with printer for personal use.
On New Year's Day, we always look forward to New Year's cards with pictures depicting the animal symbol of the year that originates from Oriental Zodiac from our friends.
