Gengo is the name of the Imperial era in Japan. The name of the new Imperial era will be Reiwa 令和,
The new era will begin on May 1st.

Reiwa represents auspicious harmony
I went to Taga shrine in Shiga where is said the father shrine of Ise shrine in the final day of Heisei era.
most of Japanese want to be Ise shrine even one time whole our life, but Taga shrine is its father shrine, so Taga shrine is a higher class shrine.
