Japanese clans

The old clans (gōzoku) mentioned in the Nihon Shoki and Kojiki lost their political power before the Heian period, during which new aristocracies and families, kuge, emerged in their place.

After the Heian period, the samurai warrior clans gradually increased in importance and power until they came to dominate the country after the founding of the first shogunate.

Japan traditionally practiced cognatic primogeniture, or male-line inheritance in regard to passing down titles and estates.

The list below is a list of various aristocratic families whose families served as Shugo, Shugodai, Jitō, and Daimyo Zaibatsu were the industrial and financial vertically integrated business conglomerates in the Empire of Japan, whose influence and size allowed control over significant parts of the Japanese economy from the Meiji period until the end of World War II.

According to the book Shinsen Shōjiroku compiled in 815, a total 326 out of 1,182 families in the Kinai area on Honshū were regarded as people with foreign genealogy.
