The original intention of the royal family refers to the Tokugawa family, the Tokugawa family, the Tokugawa family in Jizhou, and the Mitodagawa family all had the right to inherit foreign generals, that is, the so-called Tokugawa royal family, in addition to the Tokugawa family.

There are three branches of Tokugawa family who are qualified to be the successors of shogunate generals: Tokugawa family (this branch), Tokugawa family (tail Zhangfan, ancestor of Tokugawa Shinyuki, the ninth son of Tokugawa Ieyasu), and Tokugawa family of Jizhou (Wakayama Fan, ancestor of Tokugawa Laixuan, the tenth son of Tokugawa Ieyasu).

He served as the three major families in Yan Na: Wei Dechuan family, Jizhou Dechuan family and Hejun Dechuan family (Tokugawa Tadashi, the third son of the second generation general Tokugawa Hideyoshi, died of natural causes and was childless).

In the middle and late edo shogunate, there were three Tokugawa royal families: Tokugawa family, Jizhou Tokugawa family and Mitodagawa family. The ancestor of Mitokawa family is Tokugawa Ieyasu's 11th son Tokugawa Laifang. But according to the regulations of Tokugawa Ieyasu, only the top two are qualified to be generals. The duty of the Mittodchuan family is to assist the deputy generals of the shogunate. They are qualified to put forward candidates for generals, but they cannot directly become generals.
