The logo of MUJI is a customized logo, not a ready-made font. Its designer is Kazuo Tanaka. English part of MUJI logo. The fonts used by MUJI CI are mainly Japanese: A-OTF Gothic MB 10 1 PRODB (manufactured by Morizawa Company of Japan, reference price is 27,300 yen) and Spanish: Helvetica? (Generally, Helvetica of Roman of Linotype Company is used as an insert) Gothic MB1kloc-0/pro of Morizawa Company has seven words of L, R, M, DB, B, H and U. When Muji brochures need to use the Ming Dynasty (Song Dynasty), "This Ming Dynasty" (produced by Ryobi Company) is used. These can be found in official website's PDF file properties. In addition, the western language uses Helvetica, which is mentioned in the documentary of Helvetica. As for the font Nimbus Sans itself, it is a free version of URW++ based on Helvetica, and both of them have the same glyph, but they are not directly related to MUJI. The author mainly refers to the CI font of MUJI, such as the bold characters used in web pictures and print advertisements, which is Morizawa's "ゴシック12463MB101pro b", that's right. But we can be sure that the font of "Muji" in the logo does not belong to the family of "ゴシッ12463mb101",which is obvious. Download brochures from official website? You can see that.
