🧐 Frequently Asked Questions

What is "Kazue-doshi" (Traditional Age)? In the traditional Japanese system, a child is one year old at birth and gains a year every New Year's Day. While modern Japan uses the standard "Full Age" system, Kazue-doshi is still used for certain religious ceremonies and "unlucky years" (Yakudoshi).

Does it handle "Early Births" (Hayaumare)? Yes. Because the Japanese school year begins in April, children born between January 1st and April 1st are in the same grade as those born in the previous year. This tool accounts for that cutoff to ensure your school history is accurate.

Is it free? Yes. The tool is free to use and runs entirely in your browser to ensure your data stays private.

📚 Era Trivia

The current era, Reiwa, began in 2019. Its name is derived from the Man'yoshu, the oldest collection of Japanese poetry. It follows the Heisei era (1989–2019) and the Showa era (1926–1989). Showa remains the longest-lasting era in history, spanning 64 years.
