Jomei

was the 34th emperor of Japan, according to the traditional order of succession.

Jomei's reign spanned the years from 629 through 641.

Traditional narrative Before Jomei's ascension to the Chrysanthemum Throne, his personal name (imina) was or . As emperor, his name would have been Okinagatarashihi Hironuka Sumeramikoto (息長足日広額天皇).

He was a grandson of Emperor Bidatsu, both paternally and maternally. His father was Prince Oshisakanohikohito-no-Ōe, his mother was Princess Nukate-hime, who was a younger sister of his father.

Events in Jomei's reign He succeeded his great-aunt, Empress Suiko. Suiko did not make it clear who was to succeed her after her death. Before her death in 629, she called Tamura and Prince Shōtoku's son, Prince Yamashiro-no-Ōe, and gave some brief advice to each of them. After her death the court was divided into two factions, each supporting one of the princes for the throne. Soga no Emishi, the head of Soga clan, supported Tamura. He claimed that Empress Suiko's last words suggested her desire that Tamura succeed her to the throne. Scholars then construed that the succession (senso) was received by Tamura. Shortly thereafter, he is said to have acceded to the throne (sokui) as Emperor Jomei. Prince Yamashiro-no-Ōe was later attacked by the Soga clan and committed suicide along with his entire family.

Jomei's contemporary title would not have been tennō, as most historians believe this title was not introduced until the reigns of Emperor Tenmu and Empress Jitō. Rather, it was presumably Sumeramikoto (written the same way as tennō: 天皇) or Amenoshita Shiroshimesu Ōkimi (治天下大王), meaning "the great king who rules all under heaven". Alternatively, Jomei might have been referred to as (ヤマト大王/大君) or the "Great King of Yamato".

Emperor Jomei did not seek to name an heir, and Prince Yamashiro, his political rival, was still alive. In order to ensure peace between Yamashiro and his family, and Jomei's own children, the throne passed to his wife and niece, who became Empress Kōgyoku.

Poetry The Man'yōshū includes poems attributed to emperors and empresses, including "Climbing Kagu-yama and looking upon the land", which is said to have been composed by Emperor Jomei:

Countless are the mountains in Yamato, But perfect is the heavenly hill of Kagu; When I climb it and survey my realm, Over the wide plain the smoke-wreaths rise and rise, Over the wide lake the gulls are on the wing; A beautiful land it is, the land of Yamato! – Emperor Jomei
