The established usage in respect of the Imperial succession of Japan has always been in the main that of primogeniture on male lines. There had been, however, no hard-and-fast restriction similar to the Salic Law before the promulgation of the Imperial House Law of 1889, and, accordingly, we have had several empresses on the throne of Japan, though there was never an instance of a reigning empress having a consort. The Imperial House Law has prevented for ever any female succeeding to the throne. We can therefore sum up the order of succession to the Japanese throne as that of the male primogeniture, viz., from the father to the eldest son, then to the eldest grandson and so on, in the direct line, in default of which, to the collateral line. The order of all these is similar to that which appertains to European primogeniture. The ceremony of coronation is always to take place at Kioto, the old capital, so also is the Daijo-Sai, the grand festivity, which is celebrated but once in a reign. The full age of the emperor, the crown prince, and the eldest son of the crown prince, who has become direct heir to the throne owing to the early death of the crown prince, is fixed at full eighteen years, whilst with all the other members of the Imperial family it is full twenty years, like ordinary subjects of the emperor. When the emperor is a minor, a regency is to be instituted. When the emperor is incapacitated by grave causes from discharging his functions, the same thing also takes place. The order in which the regency may devolve upon members of the Imperial family is as under: (1) The crown prince. (2) The Imperial grandson, being already direct heir-apparent. (3) Other princes. (4) The empress. (5) The empress-dowager. (6) The grand empress-dowager. (7) Princesses who have actually no consorts. Precedence amongst the princes is determined by the order in which they stand for succession to the throne, and that of princesses is determined in a similar way. During the minority of the emperor, a grand guardian (Taifu) is appointed. In case no person for that office be named by the will of the departed emperor, he is to be appointed by the regent after having consulted the Imperial family council and the Privy Council. He cannot be removed unless the matter first be submitted to the consideration of the above-named councils. When a prince or princess is appointed regent, he or she shall not, during the tenure, abdicate in favour of any one except in the case where the crown prince or his eldest son, who had already become direct heir to the throne, has become qualified for the function on account of his attaining full age.
