The animals were rat, ox, tiger, hare, rabbit, dragon, serpent, horse, sheep, monkey, rooster, dog and boar. There are many annual events associated with this calendar in Japan, for example, on the day of the Ox in mid-summer, people eat eels to relieve fatigue. Furthermore, fortune-telling associated with this calendar is also popular. There is also a peculiarly Japanese belief that blood type determines your personality. There is no scientific evidence to support this claim, but it is surprisingly widespread among Japanese people, and it has become a popular belief. In Japan, you are more likely to be asked about your blood type than your zodiac sign. The idea that blood type determines one’s personality has been proposed in recent years. After the death of its proponent, several books have been published and have gained in popularity. If you watch daily TV programs, you can see how much this idea has captured the hearts and minds of the Japanese people.
