"Kar\u014D (\u5BB6\u8001, house elder) were top-ranking samurai officials and advisors in service to the daimyo of feudal Japan.In the Edo period, the policy of sankin k\u014Dtai (alternate attendance) required each daimyo to place a kar\u014D in Edo and another in the home han (feudal domain). A kar\u014D who was in charge of a castle was called the j\u014Ddai kar\u014D (\u57CE\u4EE3\u5BB6\u8001), while the one in Edo was called the Edo kar\u014D (\u6C5F\u6238\u5BB6\u8001)."@en .
