semkuJapanese era & age chart
Japanese (和暦) era table — a quick chart of the Western year, the Japanese era year and the age reached in a base year for each birth year, showing the age before the birthday and on or after it.
Base year: 2026
Birth years from 110 years before the base year up to the base year are shown. The table covers 1916–2026 (111 rows). The eras included start with Meiji, so years before 1868 are not shown.

| 2026 | Reiwa 8 (令和8年) | Not yet born, so no age is shown. | 0 |
Age is counted from 0 at birth and increases by 1 on each birthday. “Before birthday” is the age before the birthday in the base year; “On/after birthday” is the age from the birthday onward. If the birth year is the same as the base year, “—” is shown before birth and 0 after.
—: not yet born, so no age is shown.
For 1912, 1926, 1989 and 2019 the era changed during the year, so two eras are shown in the same row. For example, 1989 is “Shōwa 64 / Heisei 1”. The birth year alone does not determine which era applies.
The first year of an era is written 元年 (gannen) in Japanese; this chart shows it as year 1 with the original in brackets, for example “Reiwa 1 (令和元年)”.
The zodiac is not shown. Legal age dates, school grades and insurance ages are not determined.
The birth year, base year and output range are not saved on this page.
Print and copy
In the print dialog, set the paper to Letter and the orientation to portrait. The table may run over several pages. Check the base year, the birth-year range and that no text is cut off in the preview.
If your browser’s print dialog offers saving as PDF, you can save the chart as a PDF.
Copies tab-separated text (TSV) that can be pasted into a spreadsheet. “Copy this row” copies the one row you searched for; “Copy the table” copies the rows in the output range. The header includes the base year.
Years with two eras are written in one cell, separated like “Shōwa 64 (昭和64年) / Heisei 1 (平成元年)”.

How the chart is calculated and shown
The base year minus the birth year is the age reached on the birthday in that year. Before the birthday, subtract 1. For example, a person born in 1990 is 35 before their birthday in 2026 and 36 from the birthday onward. If the base year and the birth year are the same, “—” is shown before birth and 0 after. Birth years after the base year show no age, because the person is not yet born.
The Japanese era year is the Western year minus the first year of the era, plus 1. The first year is called 元年 (gannen) rather than “year 1”; this chart writes it as 1 with the original in brackets. When the era changed during a year, both eras used in that year are shown. In 1989, January 7 and earlier is Shōwa 64 and January 8 onward is Heisei 1. In 2019, April 30 and earlier is Heisei 31 and May 1 onward is Reiwa 1. The chart works with birth years only; it does not convert a full birth date to the Japanese calendar.
The eras included are Meiji, Taishō, Shōwa, Heisei and Reiwa. 1868 is shown as Meiji 1. Eras before Meiji and dates in the old lunar calendar are not covered.
The birth years shown run from 110 years before the base year up to the base year, both ends included, but not before 1868. With 2026 as the base year, that is 1916–2026, or 111 rows. The 110-year span is simply the display range of this chart.
The default base year is the current year in Japan Standard Time (JST), where the year changes on January 1. The current year is checked when the page is opened or shown again. A past base year you choose yourself is kept. If JavaScript is disabled, the table for the base year built into the page is shown. Check the “Base year” line above the table for the year actually in use.
Because no full birth date is entered, the chart cannot determine a single age as of today. Choose the column according to whether the birthday has passed. It does not determine the date a legal age is reached, school grades, insurance ages or any other institution-specific rule.
Era sources
The era names and change dates for Meiji, Taishō and Shōwa follow the imperial rescripts and the records of the National Archives of Japan. Heisei and Reiwa follow the Era Name Act (元号法) and the cabinet orders changing the era name. The Western-year, era-year and age table is compiled by semku.
- Era Name Act (Act No. 43 of 1979, 元号法) — e-Gov
- Cabinet Order changing the era name (Cabinet Order No. 1 of 1989) — Heisei
- Cabinet Order changing the era name (Cabinet Order No. 143 of 2019) — Reiwa
- Adoption of the one-reign-one-era system (National Archives of Japan)
- The change of era to Taishō (National Archives of Japan)
- The change of era to Shōwa (National Archives of Japan)

Frequently asked questions
- How do I convert a Heisei year to a Western year?
- Add 1988 to the Heisei year. Heisei 2 is 1990 and Heisei 30 is 2018. Count the first year (元年) as 1. Heisei ran from January 8, 1989 to April 30, 2019, so take care with the month and day in the first and last years. To find a row on this page, enter the four-digit Western year.
- How old is someone born in the Shōwa era?
- Add 1925 to the Shōwa year to get the Western birth year. For example, Shōwa 60 is 1985. Check that the base year is the current year, then read “Before birthday” or “On/after birthday” in the row for 1985.
- Which Western year is Reiwa 1?
- Reiwa 1 (令和元年) is 2019. Reiwa began on May 1, 2019; up to April 30 of the same year was Heisei 31. That is why the row for 2019 shows both “Heisei 31” and “Reiwa 1”. The first year of an era is called gannen (元年) in Japanese.
- Which column should I read for the age before the birthday?
- If the birthday in the base year has not come yet, read “Before birthday”. From the birthday onward, use “On/after birthday”. For example, a person born in 1990 is 35 before their birthday in 2026 and 36 from the birthday onward. If the birth year is the same as the base year, “—” is shown before birth.
- Why do some rows show two eras?
- When the era changed during a year, two eras were used in the same Western year. For example, in 1989, January 7 and earlier is Shōwa 64 and January 8 onward is Heisei 1. The birth year alone cannot tell which one applies, so the chart shows both.
- Can I print or copy only the range I need?
- Choose the start and end year under “Birth years to output” and press “Print” or “Copy the table”. To copy just the one row you searched for, use “Copy this row”. The copied text is TSV that can be pasted into a spreadsheet. To print, choose Letter and portrait and check the contents in the preview. Highlighting a row by search does not change the output range.
Privacy on this page
The birth-year search and the age calculation run in your browser. The birth year you enter, the base year you choose and the output range are not sent to the server or put in the URL. This page does not save your input or settings in browser storage. Reloading the page returns the input and settings to their initial state.
To understand how the page is used and to improve the service, this page sends semku’s own usage statistics and automatic error reports. They go only to the dedicated endpoint under semku.com/api/telemetry/v1/. They are not used for advertising or third-party tracking.
The usage statistics include the stage of use (such as starting an operation or requesting a copy), the time it happened and fixed identifiers that distinguish the page and feature. They do not include the birth year you enter, the base year, the output range, the ages shown or the text you copy. Inputs are not sent as hashes or as size categories either. The full URL and search terms are not sent.
Operations and sessions are distinguished by randomly generated identifiers. In the browser these exist only in temporary memory and are not written to cookies or browser storage. No identification based on cookies or combined device characteristics is used.
Error reports contain the error type, code and time, and, where available, a registered program-source identifier with the line and column number. The error message text and stack traces are not sent. Usage statistics and error reports also carry the site identifier, the published build and a random record identifier. IP addresses and user-agent strings are not part of these items.
The feedback form sends the rating you chose and the text you typed in the free-text field when you press the send button. A random ID that distinguishes the submission, the page, site and published build, and the type of request are also sent. There are no fields for your name, email address or phone number, and the birth year, base year, output range or the ages shown are not attached automatically. Whatever you write in the free-text field is sent as is. Please do not enter personal data, passwords, authentication keys or payment details.
