Japanese era year converter: what year is it in Japan and how to convert any year (2026)

If you landed here looking to convert a Japanese era year to a Western year (or the other way around), here’s the short answer.

The current Japanese era is Reiwa (令和), which started on May 1, 2019. So 2026 is Reiwa 8 (令和8年). To convert any Western year to a Japanese era year, the formula is straightforward: subtract the era’s start year from your Western year and add 1. For example, 2026 − 2019 + 1 = 8, so 2026 = Reiwa 8. To go from era year to Western year, do the opposite: era start year + era year − 1.

If you just want a converter that handles all five modern eras automatically (Reiwa, Heisei, Showa, Taisho, Meiji) without doing the math yourself, use our Japanese era year converter — it works in both directions and handles edge cases like the transition years between emperors.

The five Japanese eras at a glance

Japan has been using era names (年号 nengō, or 元号 gengō) alongside the Western calendar for the entire modern period. The five eras you’ll encounter in everyday documents and conversations are:

Era	Kanji	Romaji	Start date	End date	Examples
Reiwa	令和	Reiwa	1 May 2019	present	2026 = Reiwa 8
Heisei	平成	Heisei	8 Jan 1989	30 Apr 2019	2000 = Heisei 12
Showa	昭和	Shōwa	25 Dec 1926	7 Jan 1989	1980 = Showa 55
Taisho	大正	Taishō	30 Jul 1912	25 Dec 1926	1920 = Taisho 9
Meiji	明治	Meiji	25 Oct 1868	30 Jul 1912	1900 = Meiji 33

Anything before Meiji belongs to the Edo period and earlier, where era names changed frequently and aren’t typically converted on modern documents.

How to convert: the formula

The math is simple once you’ve done it once or twice.

Western year → Era year: subtract the start year of the era and add 1.

• 1985 in Showa: 1985 − 1926 + 1 = Showa 60 (昭和60年)
• 2000 in Heisei: 2000 − 1989 + 1 = Heisei 12 (平成12年)
• 2026 in Reiwa: 2026 − 2019 + 1 = Reiwa 8 (令和8年)

Era year → Western year: add the start year of the era and subtract 1.

• Heisei 31: 1989 + 31 − 1 = 2019
• Showa 45: 1926 + 45 − 1 = 1970
• Reiwa 5: 2019 + 5 − 1 = 2023

The “+1” exists because the first year of each era is called “year 1” (元年 gannen), not “year 0”. So the era starts at 1, not at 0.

The trick is remembering the start years. Most people who deal with these regularly remember Reiwa (2019) and Heisei (1989) by heart, and look up the older ones. Which is partly why we built the Japanese era year converter — to skip the lookup entirely.

Transition years

The years 1989, 2019, and the older switch points are slightly tricky because two eras share the calendar year.

• 1989 was both Showa 64 (until 7 January, when Emperor Showa passed away) and Heisei 1 (from 8 January).
• 2019 was both Heisei 31 (until 30 April, when Emperor Akihito abdicated) and Reiwa 1 (from 1 May).

Our calculator detects these transition years automatically and shows both possibilities, so you can pick the one that matches your actual date.

Where you’ll run into Japanese era years

If you live in Japan or work with Japanese institutions, you encounter era years constantly:

• Government and municipal documents: residence certificates (住民票), driver’s licenses, tax forms, pension statements
• Hospital records and prescriptions: dates of birth, treatment dates, prescription expiries
• Bank documents: account opening dates, certificates of deposit
• Schools and universities: graduation certificates, transcripts
• Coins and stamps: Japanese coins are minted with the era year, not the Western year
• Old books and family records: anything published before 2000 will use Showa or Heisei dates
• Wedding and funeral programs: traditional ceremonies still use era dates

Even a lot of contemporary Japanese websites use era years by default, especially government portals and older corporate sites.

A note from someone who lives here

We’ve been in Japan for over a decade and, honestly, the only era year I have memorized is my own birthday — and that’s only because I’ve had to write it hundreds of times on official forms, at hospitals, on rental contracts, bank paperwork, school records for the kids, and everything else. Every other era date I look up.

That’s the reality for most long-term foreign residents: you learn yours and your immediate family’s by sheer forced repetition, and for everything else you need help. Friends’ birthdays before 1989, dates on old certificates, years on coins, building completion dates — all of it arrives in era years and needs a quick conversion to make sense.

This is partly why we built our era year converter in the first place: we needed it ourselves more than we needed it for any reader. There’s a quiet joke among long-term foreign residents that every single one of us has a calculator or notes app entry with the era equivalents we keep forgetting. We just decided to make ours public.

For Japanese-born residents the situation is different — they grew up reading era dates on documents and have many of the conversions memorized. But for anyone who arrived as an adult, it almost never becomes automatic beyond the 2-3 years you end up writing frequently enough.

Why does Japan still use era years?

It’s a fair question, and the answer is partly cultural and partly practical inertia.

Era names trace back to the 7th century in Japan and are tied to the imperial system. When a new emperor takes the throne (or, since the Meiji era, when an emperor passes or abdicates), a new era name is chosen and the year count restarts. The transition is a major cultural event — the announcement of “Reiwa” as the new era name in April 2019 was televised live, with the official handwritten kanji card displayed prominently. Era names are intentionally chosen from classical Chinese or Japanese literature to evoke specific values (Reiwa loosely means “beautiful harmony”).

In practice, Japan operates with both calendars in parallel. International business, scientific publications, and most modern websites use the Western calendar. Government documents, traditional ceremonies, and many domestic contexts still default to era years. The Japanese government formally treats both as valid for official paperwork.

So when you fill out a Japanese form and see a date field, you’ll often see something like:

昭和 ☐ 平成 ☐ 令和 ☐ 年 ___ 月 ___ 日 ___

You circle the appropriate era and write the era year. Knowing the conversion is a daily-life skill if you live here.

If you find Japanese era conversion useful, two other calculators on our site solve similar everyday questions:

• Japanese age calculator — converts your Western birth date to Japanese age (満年齢) and traditional age (数え年 kazoedoshi)
• Japanese zodiac calculator — finds the zodiac animal (干支 eto) for any year, both modern (12-year cycle) and traditional (60-year cycle)

These three together cover most date-related questions you’ll have when dealing with Japanese documents, history, or culture.

Frequently asked questions

What year is it in Japan right now? 2026 corresponds to Reiwa 8 (令和8年) in the current Japanese era system.

Why is the first year of an era called “year 1” and not “year 0”? Because Japanese era counting follows the convention used historically in East Asia: the first year of a reign is called “year 1” (元年 gannen, literally “origin year”). There’s no year 0. This is why the conversion formula has a “+1” or “−1” depending on direction.

What’s the difference between 平成 and 令和? 平成 (Heisei) was the era from 1989 to 2019, during the reign of Emperor Akihito. 令和 (Reiwa) is the current era, started May 1, 2019, when Emperor Naruhito ascended the throne.

Can I find dates from before Meiji using this calculator? No. Our calculator covers the five modern eras (Meiji onwards, from 1868). Before that, Japan was in the Edo period (1603-1868) where era names changed multiple times within emperors’ reigns, and conversion is more complex. For pre-Meiji dates you’ll want a specialized historical reference.

What’s “gannen” (元年)? Gannen (元年) means “the first year” of an era. So Reiwa 1 is also called Reiwa gannen (令和元年). They’re the same year — just two ways of writing it. You’ll often see official documents from 2019 written as 令和元年 instead of 令和1年.

How do I write a Japanese era year in formal Japanese? The standard format is era + year + 年, like 令和8年 (Reiwa 8). On forms, you’ll often select the era from a checkbox or dropdown and write only the year number. For 元年 (the first year of an era), you can also write 令和元年.

What happens if a new era starts during the year? The transition year is shared. For example, 2019 was both Heisei 31 (Jan-Apr) and Reiwa 1 (May-Dec). Documents from that year may use either, depending on the date. Our converter handles this automatically.

Is the Japanese imperial calendar the same as the Japanese era calendar? Almost. The Japanese era calendar (元号 gengō) is what we’ve been discussing — based on the reigning emperor. The Japanese imperial calendar (皇紀 kōki) is a different system that counts years from the legendary founding of Japan in 660 BC; 2026 in this system is 皇紀2686. The imperial calendar is rarely used today outside specific historical or ceremonial contexts.
