Emperor Kōkō

Emperor Kōkō (光孝天皇, Kōkō-tennō; 830 – September 17, 887) was the 58th emperor of Japan, according to the traditional order of succession. Kōkō reigned from 884 to 887.

Before the emperor's ascension to the Chrysanthemum Throne, his name (imina) was Tokiyasu Shinnō (時康親王) or Komatsu-tei. He would later be identified sometimes as "the Emperor of Komatsu". This resulted in the later Emperor Go-Komatsu adopting this name (go- meaning "later", so "Later Emperor Komatsu" or "Emperor Komatsu II"). Kōkō had four Imperial consorts and 41 Imperial sons and daughters.
