In Japanese culture, as well as in many other cultures, birthdays and zodiac signs hold great significance. The Japanese celebrate birthdays much like people in other countries, but the zodiac signs have a deeper meaning. In Japan, the zodiac is known as Juunishi and is based on the Chinese zodiac. Each year is associated with one of 12 animals and each animal has its own unique characteristics that are said to influence a person's personality and fortune.

Understanding zodiac signs can help people understand their own personality traits as well as the traits of those around them. In anime and manga, zodiac signs are often used to add depth and complexity to characters, making them more relatable and interesting to viewers.
