How to read dates in japanese documents

In Japan, years are sometimes written in the Japanese era calendar which is based on the reign of the Emperor. For instance, the Western year 1968 is 43rd year of Showa era (which started in 1926). The name of the era is changed when the Emperor on the throne is replaced by another due to the death of His Majesty or abdication.

明治 = Meiji era / "enlightened rule" (1868-1912)

大正 = Taishō era / "great righteousness" (1912-1926)

昭和 = Shōwa era / "enlightened peace" (1926-1989)

平成 = Heisei era / "peace everywhere" (1989 - 2019)

令和 - Reiwa era/"beautiful harmony" (2019 - present time)
