Editing Emperor Tenmu (section)

===Non''-nengō'' period===
The early years of Tenmu's reign are not linked by scholars to any era or ''nengō''.<ref name="t55-58"/> The Taika era innovation of naming time periods – ''nengō'' – was discontinued during these years, but it was reestablished briefly in 686. The use of ''nengō'' languished yet again after Tenmu's death until Emperor Monmu reasserted an imperial right by proclaiming the commencement of Taihō in 701.

In this context, Brown and Ishida's translation of ''Gukanshō'' offers an explanation about the years of Empress Jitō's reign which muddies a sense of easy clarity in the pre-Taihō time-frame:
::"The eras that fell in this reign were: (1) the remaining seven years of Shuchō [(686+7=692?)]; and (2) Taika, which was four years long [695–698]. (The first year of this era was ''kinoto-hitsuji'' [695].) ... In the third year of the Taika era [697], Empress Jitō yielded the throne to the Crown Prince."<ref>Brown, p. 270.</ref>
