We send New Year's cards called nengajo on New Year's Days in Japan.
We often draw the design of 干支（ETO）on nengajo.
ETO is Zodiac which was imported from Ancient China.
There are 12 animals,Each year has a symbolic animal.
The cycle is completed every twelfth year.
The order is : rat, bull, tiger, rabbit, dragon, snake, horse, sheep, monkey, rooster, dog, boar.
This is the year of the dog.
