These are the institutions the Immigration Services Agency has designated under the 留学 (student) residence status. Designation is what lets a school sponsor a student visa, and it is the fact worth checking before you apply anywhere.
That the agency has listed the institution, and nothing more. It is not a rating, not an inspection of teaching, and not a statement that the school is good. A school can be designated and still be the wrong school for you.
A school that is not on this list cannot sponsor a student visa. That is the one thing designation settles, and no aggregator can tell you it reliably.
The agency’s list carries each institution’s name and prefecture and nothing else, so there is no address, telephone number or website to show here. To reach a school, search the name it is listed under.
Names and prefectures come from Immigration Services Agency of Japan (出入国在留管理庁), 告示された日本語教育機関等, 令和8年8月7日 (2026-08-07). English names, where they appear, come from a separate agency document, （参考）留学告示別表第１の日本語教育機関の英語表記（Japanese-Language Institutes）, 令和8年8月7日 (2026-08-07). Where the agency publishes no English name we say so rather than translating one ourselves. Both documents were retrieved and reconstructed on 2026-08-14.

Since 2024 there is a second, separate system: 認定日本語教育機関, certified by the Ministry of Education. It is not the same thing as being designated by the Immigration Services Agency, and a school can be on one list without being on the other.
An institution designated under the current 法務省告示 must obtain certification from the Minister of Education by 2029-03-31 （令和11年3月31日）. After that date it cannot continue to accept students under the 留学 residence status.
A school not certified today may well be certified next year. This is a regulatory status with a deadline, not a judgement about teaching quality.
現行の法務省告示をもって定められた日本語教育機関については、令和１１年３月３１日までに文部科学大臣による認定を受ける必要があります。
Immigration Services Agency of Japan (出入国在留管理庁), 日本語教育機関の告示基準に基づく各種報告について. Retrieved 2026-08-14. The same date appears in Agency for Cultural Affairs (文化庁)’s 日本語教育機関認定法 よくある質問集, Q104 as 令和10年度末.
Because the two lists cannot be matched school by school. They name different things: the certified list includes branch campuses and divisions that do not appear as separate entities on the designated list. Matching them by name would produce confident answers that are sometimes wrong, and being wrong about this costs a student a visa route rather than an afternoon.
Read the ministry’s own list. It is published in Japanese and it is the only authoritative answer: 認定日本語教育機関の認定結果 › If the school you are considering is not on it, ask the school directly whether it has applied and what stage it has reached. That is a fair question and a school that is applying will have an answer.
