The new requirements in detail
When it applies
The revised guideline applies to applications filed on or after April 1, 2027. Some income-related parts already apply to applications filed from April 1, 2026. Check the official procedures page for which version applies to you.
1. Japanese ability (B1 or above)
The guideline refers to the "Reference Framework for Japanese Language Education" (2021), which is based on the CEFR. B1 is an "independent user" who can handle everyday situations. The guideline itself does not name a specific test. Some applicants are not required to show B1, for example highly skilled professionals and their families, people who received 6 or more years of elementary/secondary education, and certain children of permanent residents born in Japan.
2. Understanding of Japan's systems and rules
Understanding will be checked by a method designated by the Commissioner of the Immigration Services Agency, centering on matters in the "Guidebook on Living and Working". The method had not been announced as of the date below.
