The first year of Reiwa – new era name of Japan
Then new imperial era “令和(Reiwa)” began on 1st May 2019 in Japan. 元年 means the first year.
Reiwa consists of two kanji characters of Rei 令 and Wa 和. As for the meaning, there are several English translation such as “order and harmony” and “auspicious and peace” according to some foreign media.
Alongside the Western calendar, we are familiar with the era name called gengo “元号” in daily life. This is used for the length of an emperor’s reign in Japan.
I found a convenient FAQ page published in April in Kyodo News.
Q&A: What is gengo and why is its change so important in Japan?
