Japanese era from April 859 to April 878

Jōgan (貞観) was a Japanese era name (年号,, nengō,, lit. "year name") after Ten'an and before Gangyō. This period started in April 859 and ended in April 877.[1] During this time, the emperors were Seiwa-tennō (清和天皇) and Yōzei-tennō (陽成天皇).[2]

  • 870 (Jōgan 11): Sadaakira was named Seiwa's heir.[5]
  • 876 (Jōgan 17, 11th month): In the 18th year of Seiwa's reign, the emperor abdicated. His five-year-old son received the succession (senso).[6] Soon after,[7] Emperor Yōzei accepted the monarch's role and duties and powers (sokui).[5] This was confirmed in ceremonies.[8]

A collection of laws issued after 811 was published during this era. It was called the Jōgan kyaku-siki.[9]
