Reiwa is the current era of Japan. It began on 1 May 2019, the day on which Emperor Akihito's elder son, Naruhito, ascended the throne as the 126th Emperor of Japan. The day before, then-Emperor Akihito abdicated the Chrysanthemum Throne, marking the end of the Heisei era.

The year 2019 corresponds with Heisei 31 from 1 January through 30 April, and with Reiwa 1 (令和元年 Reiwa gannen, 'the first year of Reiwa') from 1 May. Reiwa is interpreted as "beautiful harmony".
