When half the ruling party (and 8 out of 10 recent prime ministers) have inherited their seats:
After the last election, 185 of 480 Diet members (39 percent) were second- or third- (or more) generation politicians ('seshuu seijika'). Of 244 members of the LDP (the ruling party for practically the entire postwar period), 126 (52 percent) are seshuu seijika. Likewise eight of the last 10 prime ministers, and around half the Shinzo Abe and Yasuo Fukuda Cabinets. When the average turnover of lawmakers per election is only around 3 percent, you have what can only be termed a political class.Debito is a bit in-your-face but rarely significantly wrong in his facts, so I see no reason to doubt these figures. I'd be interested to hear of equivalent stats for other countries. I know that in the UK "Fatty" Soames is related to Churchill, for example. And of course the USA has its dynasties of Bushes, Kennedys and Clintons (although perhaps the last ones were both destined for politics before they got together). There's a Mussolini in Italy, but I can't help but think that the fame of these few cases may be a sign of their relative rarity.
