Emperor Go-Sai (後西天皇 Go-Sai-tennō), also called Emperor Go-Saiin (後西院天皇 Go-Saiin-tennō) (January 1, 1638 – March 22, 1685) was the 111th emperor of Japan, according to the traditional order of succession. He reigned from January 5, 1655 to March 5, 1663. His personal name was Nagahito (良仁); and his pre-accession title was Hide-no-miya (秀宮).[1]

This 17th century sovereign was named after the 9th century Emperor Junna and go- (後), translates literally as "later;" and thus, he could have been called the "Later Emperor Junna". Emperor Go-Sai could not pass the throne onto his descendants. For this reason, he was known as the Go-Saiin emperor, after an alternate name of Emperor Junna, who had confronted and reached an accommodation with similar issues. This emperor was also called "Emperor of the Western Palace" (西院の帝 Saiin no mikado ?). The Japanese word "go" has also been translated to mean the "second one;" and thus, this emperor might be identified as "Junna II". During the Meiji Era, the name became just Go-Sai.

Events of Go-Sai's life

Initially marrying the daughter of the first Takamatsu-no-miya Yoshihito (高松宮好仁親王), he succeeded as second Takamatsu-no-miya. When his elder brother, Emperor Go-Kōmyō died on January 5, 1655, Prince Nagahito received the succession (senso); and shortly thereafter, Emperor Go-Sai formally acceded to the throne (sokui).[2] This Imperial prince became the emperor as a temporary measure until his younger brother, Imperial Prince Satohito (識仁親王), who had been adopted by Emperor Go-Kōmyō, could grow older.

  • 1655 (Meireki 1): The new ambassador of Korea, arrived in Japan.[1]
  • March 2-3, 1657 (Meireki 3, 18-19th days of the 1st month): The city of Edo was devastated by a violent fire.
  • 1659 (Manji 5): In Edo, construction begins on the Ryogoku Bridge (ryogokubashi).[1]
  • March 20, 1662 (Kanbun 2, 1st day of the 2nd month): There was a violent earthquake in Miyako which destroyed the tomb of the Taiko.[1]
  • 1662 (Kanbun 2): Emperor Gosai ordered Tosa Hiromichi 土佐広通 (1561-1633), a Tosa school disciple, to adopt the name Sumiyoshi (probably in reference to a 13th century painter, Sumiyoshi Keinin 住吉慶忍), upon assuming a position as official painter for the Sumiyoshi Taisha 住吉大社).[3]
  • March 5, 1663 (Kanbun 3, 26th day of the 1st month): Emperor Go-Sai abdicates, which meant that the Prince Satohito received the succession (senso). Shortly thereafter, Emperor Reigen formally acceded to the throne (sokui).[4]

After abdicating, Go-sai put his heart into scholarship and he left behind many books, including the "Water and Sun Collection" (Suinichishū, 水日集). He was talented in waka; and he had a profound understanding of the classics.

During his reign, because of great fires at the Grand Ise Shrine, Osaka Castle, and the Imperial Palace, among others, the Great Meireki Fire, earthquakes in the region, and because of repeated floods, many people blamed the Emperor, saying he lacked moral virtue.

  • March 26, 1685 (Jōkyō 2, 22nd day of the 2nd month): Former-Emperor Go-Sai died; and a great comet was observed crossing the night sky.[5]

Emperor Go-Sai is enshrined in the imperial mausoleum, Tsukinowa no misasagi, at Sennyū-ji in Higashiyama-ku, Kyoto. Also enshrined are Go-Sai's immediate predecessors, Emperor Go-Mizunoo, Empress Meishō and Go-Kōmyō. Go-Sai's immediate Imperial successors, including Reigen, Higashiyama, Nakamikado, Sakuramachi, Momozono, Go-Sakuramachi and Go-Momozono, are enshrined here as well. [6]

At the at Kitano Shrine, a tablet over the Chu-mon entryway reads tenmangu in the calligraphy of Emperor Go-sai.[7]


Kugyō (公卿) is a collective term for the very few most powerful men attached to the court of the Emperor of Japan in pre-Meiji eras. Even during those years in which the court's actual influence outside the palace walls was minimal, the hierarchic organization persisted.

In general, this elite group included only three to four men at a time. These were hereditary courtiers whose experience and background would have brought them to the pinnacle of a life's career. During Go-Sai's reign, this apex of the Daijō-kan included:
