Emperor K?k? (Уぱ K?k?-tenn?, 830  August 26, 887) was the 58th emperor of Japan, according to the traditional order of succession. K?k? reigned from 884 to 887. Before his ascension to the Chrysanthemum Throne, his personal name was Tokiyatsu (眃克) 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'). Tokiyatsu Shinn? was the third son of Emperor Nimmy?. His mother was Fujiwara no Sawako. K?k? had four Imperial consorts and 41 Imperial sons and daughters.
