Japanese era and modern reign names

 

The following table is meant as a quick guideline to Japanese era names since 645 CE. Dates are provided down to the month (lunar months up to the end of 1872); the precise dates would be different under the Gregorian calendar.

It should be remembered that modern reigns end and begin in the same year, so that one calendar year may contain both the last year of the old reign and the first year of the new reign. The Shōwa Emperor, for example, died on January 7, 1989, meaning that 1989 was both Shōwa 64 and Heisei 1, with the latter starting from January 8, the day after the emperor's death. The very rough listing of historical events relies heavily on the chronologies in The Cambridge History of Japan, although in some cases preference has been given to Japanese sources. Corrections to mistakenly entered data will be gratefully received at Contact.

Note: Intercalary months are indicated by an asterisk.

645.6 - 650.2 Taika 大化 645 Taika (Great) Reform; capital moved to Naniwa.
650.2 - 654.10 Hakuchi (Hakuhō) 白雉 (白鳳) Hakuhō can be used to refer to the same era as Hakuchi, occupying the latter half of the reign of Emperor Kōtoku. Hakuhō was also apparently used intermittently as an unofficial era name until 686. The Hakuhō period in art generally refers to the years between the Taika Reform of 645 and the establishment of the capital in Nara in 710.
654.10 - 686.7 (Hakuhō) (白鳳) No official era name exists for this period, although "Hakuhō" seems to have been used occasionally on an unofficial basis. The Hakuchi/Hakuhō ambiguity is further compounded by scholars who contend that "Hakuhō" refers to a period (661-683) under the "Kyūshū court" as postulated by Yoshida Takehiko.

667 Capital moved to Ōtsu in Ōmi Province.
