Non-nengō period The years of Tenji's reign are not linked by scholars to any era or nengō. The Taika era innovation of naming time periods – nengō – languished until Mommu reasserted an imperial right by proclaiming the commencement of Taihō in 701 (aside from the momentary proclamation of the Shuchō era under Emperor Tenmu in 686). See Japanese era name – "Non-nengo periods" See Tenji period (661).
