孝謙天皇
The years of Junnin's reign, 758–765, are more specifically encompassed within a single era name or "nengō"."Tenpyō-hōji" Junnin seemingly had very little power and was possibly a mere figurehead. In 764, six years after Empress Kōken had stepped down, the former empress reclaimed the throne during the Fujiwara no Nakamaro Rebellion, forcing Junnin to abdicate.
