Kasumi Kaikan

The Kasumi Kaikan (霞会館) is the association of the former "kazoku" of Japan.
It was originally called the "Kazoku Kaikan" (華族会館), or Peers' Club, and renamed in 1947. The association used to have its headquarter in the "Rokumeikan" building.
The association is a social club, similar to a gentlemen's club but women are also members. Membership is strictly limited to descendants of the "kazoku". Emperor Akihito and Empress Michiko as well as other members of the Japanese imperial family visit the club for special occasions.
The association owns the Kasumigaseki Building in Kasumigaseki, 36-story skyscraper, and has its club rooms on the 34th floor.
