Japan Know How archive
Meiji, Taisho, Showa, Heisei and Reiwa converted in both directions, plus the transition years that catch people out. Also the traditional kazoedoshi age count, which can put you two years above your Western age and still shows up in temple ceremonies and family customs.
Japanese Eras
Japanese documents do not use one consistent calendar. Follow the same date across a driver’s license, residence card and family register to see where Western years appear, where era conversion is required and how copying a date literally can create a form error.
Japanese Eras
Japan has not banned Western years from official paperwork. The real rule is form by form: family-register records favor era years, residence cards use Western dates, and licenses mix both. This guide shows how to read the field before entering a date.

Heisei ended in 2019, but its flip phones, purikura, loose socks, and gyaru styling already look retro to young consumers. Here are the Japanese terms that explain how a recent era became a cultural label.
Japanese Eras
Hirohito, Emperor Showa, Naruhito, and Emperor Emeritus Akihito are not interchangeable labels. The correct choice depends on whether the emperor is reigning, retired, or deceased—and whether you are writing in English or Japanese.
Japanese Eras

Japanese Eras
Every earlier era name traced back to a Chinese classic. Reiwa was pulled from an eighth-century Japanese poetry preface, and that was the whole point.
Japanese Eras
Suga held the card up before midday, thirty years after Obuchi did the same for Heisei. What happened in the room, and why the name stayed sealed.
Japanese Eras
Scholars submit candidates, a cabinet picks one, and a country repaints its forms. The rules a new era name must pass and who actually signs off.
