No Japanese language institution is designated in Tokushima 徳島県. The Immigration Services Agency’s list covers every prefecture, and it names none here.

Studying at one of them means living within reach of it: a student visa is tied to the institution that sponsors it, not to the prefecture you would prefer.
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 shown, come from （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). Those are the PUBLISHER’s dates. Checked 14 August 2026, which is when we retrieved and reconstructed them.
