Emperor of Japan - Succession

Succession

The Japanese imperial dynasty bases its position in the expression that it has "reigned since time immemorial" (万世一系 bansei ikkei). It is true that its origins are buried in the mists of time: there are no records of any emperor who was not said to have been a descendant of other, yet earlier emperors. There is suspicion that Emperor Keitai (c. 500 AD) may have been an unrelated outsider, though the sources state that he was a male-line descendant of Emperor Ōjin. However, his descendants, including his successors, were according to records descended from at least one and probably several imperial princesses of the older lineage. The tradition built by those legends has chosen to recognize just the putative male ancestry as valid for legitimizing his succession, not giving any weight to ties through the said princesses. Millennia ago, the Japanese imperial family developed its own peculiar system of hereditary succession. It has been non-primogenitural, more or less agnatic, based mostly on rotation. Today, Japan uses strict agnatic primogeniture, which was adopted from Prussia, by which Japan was greatly influenced in the 1870s.

The controlling principles and their interaction were apparently very complex and sophisticated, leading to even idiosyncratic outcomes. Some chief principles apparent in the succession have been:

• Women were allowed to succeed (but there existed no known children of theirs whose father did not also happen to be an agnate of the imperial house, thus there is neither a precedent that a child of an imperial woman with a non-imperial man could inherit, nor a precedent forbidding it for children of empresses). However, female accession was clearly much more rare than male.
• Adoption was possible and a much used way to increase the number of succession-entitled heirs (however, the adopted child had to be a child of another member agnate of the imperial house).
• Abdication was used very often, and in fact occurred more often than death on the throne. In those days, the emperor's chief task was priestly (or godly), containing so many repetitive rituals that it was deemed that after a service of around ten years, the incumbent deserved pampered retirement as an honored former emperor.
• Primogeniture was not used—rather, in the early days, the imperial house practised something resembling a system of rotation. Very often a brother (or sister) followed the elder sibling even in the case of the predecessor leaving children. The "turn" of the next generation came more often after several individuals of the senior generation. Rotation went often between two or more of the branches of the imperial house, thus more or less distant cousins succeeded each other. Emperor Go-Saga even decreed an official alternation between heirs of his two sons, which system continued for a couple of centuries (leading finally to shōgun-induced (or utilized) strife between these two branches, the "southern" and "northern" emperors). Towards the end, the alternates were very distant cousins counted in degrees of male descent (but all that time, intermarriages occurred within the imperial house, thus they were close cousins if female ties are counted). During the past five hundred years, however, probably due to Confucian influence, inheritance by sons—but not always, or even most often, the eldest son—has been the norm.

Historically, the succession to Japan's Chrysanthemum Throne has always passed to descendants in male line from the imperial lineage. Generally they have been males, though of the over one hundred monarchs there have been nine women (one pre-historical and eight historical) as Emperor on eleven occasions. See the male line of the Yamato dynasty.

Over a thousand years ago, a tradition started that an emperor should ascend relatively young. A dynast who had passed his toddler years was regarded suitable and old enough. Reaching the age of legal majority was not a requirement. Thus, a multitude of Japanese emperors have ascended as children, as young as 6 or 8 years old. The high-priestly duties were deemed possible for a walking child. A reign of around ten years was regarded a sufficient service. Being a child was apparently a fine property, to better endure tedious duties and to tolerate subjugation to political power-brokers, as well as sometimes to cloak the truly powerful members of the imperial dynasty. Almost all Japanese empresses and dozens of emperors abdicated, and lived the rest of their lives in pampered retirement, wielding influence behind the scenes. Several emperors abdicated to their entitled retirement while still in their teens. These traditions show in Japanese folklore, theater, literature and other forms of culture, where the emperor is usually described or depicted as an adolescent.

Before the Meiji Restoration, Japan had eleven reigns of reigning empresses, all of them daughters of the male line of the Imperial House. None ascended purely as a wife or as a widow of an emperor. Imperial daughters and granddaughters, however, usually ascended the throne as a sort of a "stop gap" measure—if a suitable male was not available or some imperial branches were in rivalry so that a compromise was needed. Over half of Japanese empresses and many emperors abdicated once a suitable male descendant was considered to be old enough to rule (just past toddlerhood, in some cases). Four empresses, Empress Suiko, Empress Kōgyoku (also Empress Saimei) and Empress Jitō, as well as the mythical Empress Jingū, were widows of deceased emperors and princesses of the blood imperial in their own right. One, Empress Gemmei, was the widow of a crown prince and a princess of the blood imperial. The other four, Empress Genshō, Empress Kōken (also Empress Shōtoku), Empress Meishō and Empress Go-Sakuramachi, were unwed daughters of previous emperors. None of these empresses married or gave birth after ascending the throne.

Article 2 of the 1889 Meiji Constitution (the Constitution of the Empire of Japan) stated, "The Imperial Throne shall be succeeded to by imperial male descendants, according to the provisions of the Imperial House Law." The 1889 Imperial Household Law fixed the succession on male descendants of the imperial line, and specifically excluded female descendants from the succession. In the event of a complete failure of the main line, the throne would pass to the nearest collateral branch, again in the male line. If the empress did not give birth to an heir, the emperor could take a concubine, and the son he had by that concubine would be recognized as heir to the throne. This law, which was promulgated on the same day as the Meiji Constitution, enjoyed co-equal status with that constitution.

Article 2 of the Constitution of Japan, promulgated in 1947 by influence of the U.S. occupation administration and still in force, provides that "The Imperial Throne shall be dynastic and succeeded to in accordance with the Imperial Household Law passed by the Diet." The Imperial Household Law of 16 January 1947, enacted by the ninety-second and last session of the Imperial Diet, retained the exclusion on female dynasts found in the 1889 law. The government of Prime Minister Yoshida Shigeru hastily cobbled together the legislation to bring the Imperial Household in compliance with the American-written Constitution of Japan that went into effect in May 1947. In an effort to control the size of the imperial family, the law stipulates that only legitimate male descendants in the male line can be dynasts; that imperial princesses lose their status as Imperial Family members if they marry outside the Imperial Family; and that the Emperor and other members of the Imperial Family may not adopt children. It also prevented branches, other than the branch descending from Taishō, from being imperial princes any longer.
