The cadet royal families lost membership in the Imperial Family by the American Occupation Authorities in October 1947, as part of the abolition of collateral imperial houses and the (hereditary peerage). However, there are still unofficial heads of the living collateral families. These are the living : The Higashifushimi or Komatsu collateral branch became extinct in the male line in 1922, followed by the Nashimoto branch in 1951, Kachō or Kwachō branch in 1970, Yamashina branch in 1987, and Kitashirakawa branch in 2018.
