The Imperial House of Japan (皇室 kōshitsu?), also referred to as the Imperial Family, or the Yamato Dynasty, comprises those members of the extended family of the reigning Emperor of Japan who undertake official and public duties. Under the present Constitution of Japan, the emperor is the symbol of the state and unity of the people. Other members of the imperial family perform ceremonial and social duties, but have no role in the affairs of government. The duties as an emperor are passed down the line to children and their children's children and so on.

The Japanese monarchy is the oldest continuous hereditary monarchy in the world still in existence. The imperial house recognizes 125 legitimate monarchs since the accession of Emperor Jimmu (traditionally dated to February 11, 660 BC), including the reigning emperor, Akihito; see its family tree.

The 1947 Imperial Household Law defines the imperial house as: the Emperor of Japan (天皇 tennō?); the empress (皇后 kōgō?); the empress dowager (皇太后 kōtaigō?); the grand empress dowager (太皇太后 tai-kōtaigō?); the crown prince (皇太子 kōtaishi?) and his consort (皇太子妃 kōtaishihi?); the imperial grandson who is heir apparent (kōtaison, 皇太孫) and his consort; the male-line Imperial grandsons (親王 shinnō?) and their consorts; the unmarried male-line Imperial granddaughters (内親王 naishinnō?); Imperial Princes ( ō?) and their consorts; and the Imperial Princesses (女王 nyoō?). The legitimate children and male line grandchildren of an emperor are 親王 shinnō (imperial princes) in the case of males and 内親王 naishinnō (imperial princesses) in the case of females. More distant male line descendants are ō (princes) or nyoō (princesses).

After the removal of eleven collateral branches from the Imperial House in October 1947, the official membership of the imperial family has effectively been limited to the male line descendants of the Emperor Taishō, excluding females who married outside the imperial family and their descendants.

There are presently 23 members of the imperial family:

Living former members

Under the terms of the 1947 Imperial Household Law, naishinnō (imperial princesses) and nyoō (princesses) lose their titles and membership in the imperial family upon marriage, unless they marry the Emperor or another member of the imperial family. Three of the five daughters of Emperor Shōwa, the two daughters of Prince Mikasa, and most recently, the only daughter of the Emperor Akihito left the imperial family upon marriage, taking the surnames of their husbands. The eldest daughter of Emperor Shōwa married the eldest son of Prince Higashikuni Naruhiko in 1943. The Higashikuni family lost its imperial status along with the other collateral branches of the imperial family in October 1947. The living former imperial princesses are:

In addition to these former princesses, there are also several people of Imperial descent in the eleven cadet branches of the dynasty (Asaka, Fushimi, Higashi-Fushimi, Higashi-kuni, Kan'in, Kaya, Kitashirakawa, Kuni, Nashimoto, Takeda, and Yamashina) that left the imperial family in October 1947. The Shōwa emperor's eldest daughter, Higashikuni Morihito (Shigeko), and his third daughter, Takatukasa Toshimichi (Kazuko), died in 1961 and 1989, respectively.

Succession

Crown Prince Naruhito is heir apparent to the Japanese throne

Historically, the succession to the Chrysanthemum Throne has generally passed in male line of the imperial lineage. The imperial clan previously included specially designated collateral lines or shinnōke (princely houses), too. The surviving shinnōke and several other branches of the extended imperial clan (the ōke) were reduced to commoner status in 1947.

Before the Meiji Restoration, Japan had eight female tennō or reigning empresses, all of them daughters of male line of the imperial clan. None ascended purely as a wife or as a widow of an emperor. None of these empresses married or gave birth after ascending the throne.

Article 2 of the Constitution of Japan 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 1947 enacted by the 92nd 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 House 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 naishinnō (imperial princesses) and nyoō (princesses) lose their status as imperial family-members if they marry outside the imperial family; that shinnō (imperial princes), other than the crown prince, ō (princes), unmarried imperial princesses and princesses, and the widows of imperial princes and princesses may, upon their own request or in the event of special circumstances, renounce their membership in the imperial family with approval of the Imperial House Council; and that the Emperor and other members of the imperial family may not adopt children.

Before September 2006, there was a potential succession crisis since no male child had been born into the imperial family since Prince Akishino in 1965. Following the birth of Princess Aiko, there was some public debate about amending the Imperial House Law to allow female descendants of an emperor and their descendants to succeed to the throne. In January 2005, Prime Minister Koizumi Junichiro appointed a special panel of judges, university professors, and civil servants to study changes to the Imperial House Law and to make recommendations to the government. On October 25, 2005, the commission recommended amending the law to allow females in the male line of imperial descent to succeed to the throne. There is broad public support for such a change. See Japanese Imperial succession controversy.

History of titles

Standard of the Imperial Family

Ō (王) is a title (commonly translated "prince") given to male members of the Japanese Imperial Family who do not have the higher title of shinnō. The female equivalent is joō/nyoō (女王). Ō can also be translated as "king". The origin of this double meaning is a copying of the Chinese pattern. Unlike in China, however, ō was only used for imperial family members.

Historically, any male member of the Imperial Family was titled ō by default, with shinnō (親王; literally relative-prince) and its female equivalent naishinnō (内親王; literally relative-princess) being special titles granted by the Emperor. After the Meiji Restoration, the difference between ō and shinnō were altered. A shinnō or naishinnō was a legitimate Imperial Family member descended from an Emperor down to the great grandchild. The term "legitimate Imperial Family" excludes anyone not connected by a direct male line descent, as well as the descendants of anyone who renounced their membership in the Imperial Family, or were expelled from the Imperial Family. Shinnō also included the heads of any of the shinnōke. A provision of law which never had an opportunity to be applied also stipulated that if the head of a shinnōke succeeded to the Chrysanthemum Throne, then his brothers would acquire the title of shinnō, as well as their descendants (down to the grandchildren?). The Emperor could also specially grant the title of shinnō to any ō.

In 1947, the law was changed so that shinnō only extended to the male-line grandchildren of an Emperor. The Imperial Family was also drastically pruned, disestablishing the ōke and shinnōke. The consort of an ō or shinnō has the suffix -hi (妃) to ō or shinnō.
