not op but brands like visvim are way more affordable if you are in Japan. Less expensive brands like OrSlow or TCB are also more affordable in Japan (there is a wealth of fashion brands in that country).

>I think Japanese fashion is less about the clothes themselves than the acceptance to let people wear what they want and and not judging.

In my experience this mostly applies if you are young. At a certain age you are more or less expected to start fitting in the mold.
