Topic: Official Languages by Country: Who Decides?

What does Japan require?

Everyday topic

Japan has no statutory official language. The constitution does not use the term, and no act designates Japanese as official. In practice Japanese is used as a matter of course, but that rests on convention and on how individual statutes are administered, not on any provision declaring it. The closest thing is the Act on the Promotion of Japanese Language Education (Act No. 48 of 2019) — and as its title says, what it governs is the promotion of teaching, not the conferring of status: it sets out measures to widen access to Japanese-language education at home and abroad, to maintain and raise its standard, and to fund research. The absence of a designating provision is itself meaningful in this seven-way comparison: India spent a whole Part on it, Indonesia and Brazil each settled it in a sentence, the United States designated one by executive order after the fact. Japan has done none of these.

What is this topic?

Which language is official depends on where the rule lives: Indonesia and Brazil name a state language in their constitutions, India sets the Union's official language in its constitution, China promotes Putonghua through an education clause without naming an "official language", and the United States designated English by executive order in 2025.

Japan has no statutory official language, while Taiwan recognises multiple national languages.

Is the language you speak at home the same one used at school and in government offices?
