Subsequently, the power to create a calendar shifted to the shogunate and the authority of the Imperial calendar was diminished after 1684. In that year, the astrology bureau of the Tokugawa bakufu created a "Japanese" calendar which was independent of Chinese almanacs.
1684 (Jōkyō 1): Having met with success in Osaka's kabuki theater, Chikamatsu Monzaemon began to write plays for the kabuki audience in Heian-kyō. In part, his success stemmed from the way his work would sometimes mirror current happenings and contemporary urban characters.
March 26, 1685 (Jōkyō 2, 22nd day of the 2nd month): The former Emperor Go-Sai died. A large comet appeared in the night sky.
April 13, 1686 (Jōkyō 3, 21st day of the 3rd month): Emperor Reigen abdicated in favor of his son, who become Emperor Higashiyama. After abdication, Reigen's new home was called the Sentō-gosho (The Palace for an Ex-Emperor). The Jōkyō Uprising occurred in October.
December 20, 1687 (Jōkyō 4, 16th day of the 11th month): The esoteric Daijō-sai ceremony, having been in abeyance since the time of Emperor Go-Kashiwabara—for nine reigns—was revived because of the bakufu's insistence. This Shinto ritual is performed only once by each emperor during the enthronement ceremonies.
