Japanese Era Converter和暦 ⇄ 西暦 — Reiwa, Heisei, Showa and more

Convert between the Japanese era calendar and the Western year in both directions. Type a year on either side to see the result instantly.

Why this matters on a resume

Japanese forms use two calendars: the Western year (西暦) and the era year (和暦). On a rirekisho you may use either, but you must use the same one everywhere — mixing 令和 and 西暦 across your birth date, school dates, and work history is a classic mistake that makes an application look careless. This tool helps you line every date up in one system.

How the eras line up

• 令和 (Reiwa) began in 2019 — Reiwa 1 = 2019, Reiwa 8 = 2026.
• 平成 (Heisei): 1989–2019. Heisei 1 = 1989.
• 昭和 (Showa): 1926–1989.
• 大正 (Taisho): 1912–1926.
• 明治 (Meiji): 1868–1912.

In years when an era changed (1989, 2019), this converter uses the newer era, which is the usual convention on resumes. For more on choosing a system, read 令和 vs Western dates on your resume.
