Logo is always custom designed. But originally, MUJI was similar to UNIQLO in promoting the idea of ??no or downplaying the trademark. Its logo was very simple. If it were to be copied, it would look like a common ゴシック type. I have tried Huakang, Heisei, and DFP Teita, and they are all similar. There are a few others I haven’t tried yet, and there are indeed some subtle differences in the strokes.

Then use any kind of ゴシックbody of similar thickness to modify it. The MS ゴシック that comes with the system is a bit thinner, the Soeiku ゴシック that comes with Office is about the same, or you can use Heisei w3~w5
