I‘m the owner of /r/NoblesseOblige, a subreddit themed around historical nobility and the laws and traditions surrounding it. I would like to learn about Japanese nobility. I know that it is not recognized in civil law anymore but that it still forms a historical class and most Prime Ministers belong to the nobility.
* Am I right that the Japanese nobility consists of two classes – families given Peerage titles after the late 19th century which may be old or not so old, and untitled families mostly descending from Samurai and landowners as well as from Peerage titleholders?
* Is Japanese nobiliary law similar to Salic law? I.e. titles go by male primogeniture, nobility is inherited by all descendants in the legitimate male line, wives take the rank of their husbands. But in Japan, families without sons can adopt a close cousin or son-in-law instead of having the title or name go to a distant cousin or go extinct?
* Has the nobility become a largely closed class after 1945 except in cases of adoption, or is it possible for a new family to grow into it through repeated intermarriage, purchasing land etc.?
* How important is nobility in everyday life?
* Is there any interaction between Japanese and other Asian or even European nobility?
* Does the nobility still maintain its unique manners, dress style etc.?
* What are traditional noble careers?
* How many Japanese people are estimated to belong to the nobility?
* Apart from the Peers‘ Club in Tokyo, what are some other clubs consisting mostly or exclusively of nobility?
