Emperador Enclaustrado
Prince Tomohito acceded to the throne on May 2, 1687 as Emperor when his father abdicated in his favor, the era's name was changed from "Jōkyō" to "Genroku" to mark this event. While he held the political title of "Emperor", it was in name only as the shoguns of the Tokugawa family controlled Japan. Initially, Emperor Reigen continued to rule in Higashiyama's name as a Cloistered Emperor as had been done in the Heian period. While this move caused trouble by provoking the ruling shogunate, Higashiyama's gentle character helped to improve relations with the Shōgun. This warmed relationship caused imperial property to be increased, and repairs carried out on Imperial mausoleums. Reigen meanwhile lived out his retirement in the "Sentō-gosho" (the palace for an ex-Emperor), and is now known for being the last "Cloistered Emperor" of Japan. On December 20, 1688 the esoteric "Daijō-sai" ceremony was revived because of the shogunate's insistence. This Shinto ritual had been in abeyance for over a century, and is performed only once by the emperor in the period of the enthronement ceremonies.
