There are specifically two such families: that of Hisamitsu SHIMAZU, who was not the Lord of the Shimazu domain but had a great influence on the domain at the end of Edo Period as a guardian, and his descendants, and that of Yoshinobu TOKUGAWA, who transferred the headship of the family to an adopted child, Iesato TOKUGAWA, and lived in seclusion after Taisei Hokan (the transfer of power back to the Emperor), and his descendants.
具体的には、藩主ではなかったがその後見人として幕末の薩摩藩に大きな影響を与えた島津久光とその子孫、大政奉還後養子の徳川家達に家督を譲って隠棲した徳川慶喜とその子孫の2家である。
