Hakuhō period
The Hakuhō period (白鳳時代, Hakuhō jidai; "white phoenix period") was an unofficial Japanese era name (年号, nengō; "year name") of Emperor Tenmu after Hakuchi and before Suchō. The duration of this discrete non-nengō timespan lasted from 673 through 686.
The Hakuhō period is more often used as a general term which describes a wider range of years.
