Generate Japanese emperor names in the real conventions: posthumous names like Emperor Kanmu and Empress Suiko, Go- names like Emperor Go-Daigo, retired and cloistered forms like Sutoku-in, and personal names like Mutsuhito. About a third of the list is historical, from Jimmu to Showa; the rest, such as Emperor Katsura or Genroku Tenno, is invented in the same patterns for fiction.

About Japanese emperor names

History knows a Japanese emperor by a posthumous name, not his personal one. The early ones are Chinese-style virtue names (Jimmu, Tenmu, Shomu, Kanmu). From the Heian period most come from a palace, a district of Kyoto or a tomb (Saga, Daigo, Murakami, Shirakawa). A later emperor given an earlier name took the prefix Go-, "later", as in Go-Daigo and Go-Mizunoo. Since Meiji the era name serves as the emperor's name.

Other forms sit beside the regnal name. In Japanese the title follows it, as Tenno or the briefer -tei (Genroku Tenno, Hikone-tei). An emperor who abdicated was a retired emperor (Joko), and one who took Buddhist vows a cloistered emperor (Ho-o); for centuries the usual style ended in -in, as in Sutoku-in. From the later Heian period most personal names end in -hito (Mutsuhito, Osahito), while the earliest rulers carry native names such as Kamuyamato Iwarebiko. Eight women reigned in their own right, among them Suiko and Jito.

Of the 1,000 entries, 336 are historical: the traditional line from Jimmu to Showa, the Northern Court, and their retired forms, bynames, court titles and personal names. The other 664 are invented for fiction in the same patterns, mostly on place, temple and era names. No such emperors reigned, so check a name before you treat it as history.

How to choose Japanese emperor names

  • Match the form to the period: a virtue name such as Tenmu or Shomu suits an ancient court, a place name such as Emperor Katsura or Emperor Kurama suits a Heian or medieval one, and an era-style name such as Genroku Tenno suits a modern one.
  • Use Go- only on a name that already has a bearer in your setting. Emperor Go-Konoe implies an earlier Konoe, and readers who know the pattern will look for him.
  • Keep the personal name out of dialogue. Courtiers did not say an emperor's -hito name aloud; they used a title such as Shujo for the reigning emperor, or Hon'in and Shin'in for the senior and junior retired emperors. Edo-period townspeople said Tenshi-sama or Kinri-sama.
  • A posthumous name is given after death, so nobody in a scene should address a living ruler by it. Use it in narration, and in dialogue use a title or a retired form such as Suma Joko.
  • For a ruler who abdicates and still governs from behind the throne, pick a cloistered form such as Cloistered Emperor Taigen, the pattern of Shirakawa and Go-Shirakawa.

Frequently asked questions

Are all of these real Japanese emperors?

No. 336 entries are historical: the emperors and reigning empresses of the traditional line from Jimmu to Showa, the five Northern Court emperors, and their retired forms, bynames, court titles and personal names. The rest are invented for fiction in the same patterns, for example Emperor Katsura, Genroku Tenno and Emperor Go-Konoe, and no such emperors reigned. The list does not mark which is which and stops at Emperor Showa, so check a name before you use it as history.

What does Go- mean in a name like Go-Daigo?

Go- means later. It marks an emperor who was given the name of an earlier one, so Go-Daigo is the later Daigo and Go-Shirakawa the later Shirakawa. Some point back to a byname: Go-Komatsu refers to Emperor Koko, who was also called Komatsu no Mikado, and Go-Kashiwabara to Emperor Kanmu, known as Kashiwabara no Mikado.

Why does an emperor have both a regnal name and a personal name?

The name history uses, such as Meiji or Kanmu, was given after death. In life the same man had a personal name, Mutsuhito in the first case and Prince Yamabe in the second, which was not used to address him. The list keeps the two kinds as separate entries, so you can take a regnal name for the chronicle and a personal name for the years before the throne.

What is the difference between a retired and a cloistered emperor?

A retired emperor (Daijo Tenno, or Joko) had abdicated in favor of a successor. A cloistered emperor (Ho-o) was a retired emperor who had also taken Buddhist vows. In the late Heian period retired emperors such as Shirakawa, Toba and Go-Shirakawa held real power, which is why the list has forms like Cloistered Emperor Shirakawa and Toba-in.
