In Japan, the family pattern can be said to be a symbol of a family, and the history of the family pattern can also be regarded as a history of Japanese heraldry. It was not very common in ancient Japan, but with the development of modern capitalist economy, some enterprises used home to sell their own goods. It was also at this time that the number of family lines was the highest in prehistoric times. According to a Japanese statistic, the existing family line in Japan can reach more than 12000.

The origin of the family line should be in the middle of heian period, when poetry music was very popular, so some aristocratic families often went out for social activities and exchanged some experiences about poetry music. At that time, when they went to participate in activities, many cars went forward together, because the appearance of ox carts was almost the same, so it was difficult to distinguish them, so someone embedded a special pattern in a certain part of the car that could be different from ordinary people, and gradually formed each family's.

Each family model has its own unique significance. Although it was only for the convenience of identifying different families at first, with the development of history, the use of family model has actually become more and more complicated. First of all, the family pattern is a decorative group. This family pattern often comes from officials or officials' families. At that time, it was embroidered on their clothes or cars, which looked elegant. The other is as a symbol of good luck. Through this family pattern, I place my wishes for the prosperity and happiness of my family's descendants. Moreover, in order to promote religious culture, some families even integrated into religious culture.

Family model can be regarded as a special existence in Japanese traditional culture. Although it was only a design, it also entrusted many Japanese people's wishes and understanding of Japanese culture at that time.
