Japanese Era Converter
Convert between Japanese era years (wareki) and Western years, both ways. Covers Reiwa, Heisei, Showa, Taisho, and Meiji, with the zodiac animal and age.
Understanding the Japanese Calendar
Japan runs on two calendars at once. There is the Western calendar, seireki (西暦, せいれき), the same Gregorian years used across most of the world. And there is wareki (和暦, われき), the traditional Japanese system that counts years by the reign of the emperor. Ask a Japanese office worker what year it is and the answer might be 2026 or it might be Reiwa 8. Both are correct.
This converter moves between the two in either direction, and it also shows the year’s zodiac animal (eto) and a quick age reference.
The Era System
Each era, called a nengo (年号) or gengo (元号), begins when a new emperor takes the throne and the year count resets to one. The very first year of an era is not called “year 1” but gannen (元年), meaning “origin year.” So the year an era begins is always written as gannen, and the counting starts from there.
The Five Modern Eras
| Era | Kanji | Western years | Meaning |
|---|---|---|---|
| Meiji | 明治 | 1868 to 1912 | enlightened rule |
| Taisho | 大正 | 1912 to 1926 | great righteousness |
| Showa | 昭和 | 1926 to 1989 | enlightened harmony |
| Heisei | 平成 | 1989 to 2019 | achieving peace |
| Reiwa | 令和 | 2019 to present | beautiful harmony |
Reiwa holds a small distinction. Every previous era name was drawn from classical Chinese literature. Reiwa is the first taken from a Japanese source, the eighth-century poetry anthology the Man’yoshu (万葉集).
How to Convert by Hand
The math is simple once you know the offset for each era:
- Reiwa: Western year minus 2018. So 2026 is Reiwa 8.
- Heisei: Western year minus 1988.
- Showa: Western year minus 1925.
- Taisho: Western year minus 1911.
- Meiji: Western year minus 1867.
One quirk to remember: the year an era changes belongs to two eras. In 2019, January through April was still Heisei 31, and Reiwa began on May 1. The converter flags these transition years for you.
Where You Will Meet Wareki
Wareki is not a museum piece. It appears on driver’s licenses, passports, coins, birth certificates, pension and tax forms, product expiry dates, and most government paperwork. Business and international contexts lean on seireki, but the moment you fill out an official Japanese form, you will likely be asked for the era year. That is exactly when a converter earns its keep.

Frequently Asked Questions
What year is it in Japan right now?
By the Western calendar it is 2026, and in the Japanese era system that is Reiwa 8 (令和8年). The Reiwa era began on May 1, 2019, when Emperor Naruhito ascended the throne, so you find the current Reiwa year by subtracting 2018 from the Western year.
How do I convert Reiwa to a Western year?
Add 2018 to the Reiwa year. Reiwa 1 is 2019, Reiwa 6 is 2024, and Reiwa 8 is 2026. To go the other way, subtract 2018 from the Western year. The converter above does both instantly.
Why does Japan use era names instead of just numbers?
The era system ties the calendar to the reign of each emperor, a tradition that has shaped Japanese record keeping for well over a thousand years. It gives each period of history its own name and feeling, so people speak of the Showa era or the Heisei generation the way English speakers might say “the sixties.”
What is gannen?
Gannen (元年) means “origin year” and is used instead of “year 1” for the first year of any era. So the first year of Reiwa is written Reiwa gannen (令和元年), which corresponds to 2019.
What came before the Reiwa era?
Heisei (平成), which ran from 1989 to 2019 under Emperor Akihito. Before that came Showa (1926 to 1989), one of the longest and most eventful eras in Japanese history, spanning the war years and the postwar economic boom.
