Japan has a pretty hefty cultural presence with notable directors, and is pretty influential in terms of fashion, interior design, and architecture.
The usual issue is that Japanese culture is pretty understated, so the streetwear, the architecture, etc. is not something that immediately grabs attention like New York, Paris or Milan.
But see Zaha Hadid’s Tokyo Olympics stadium [1] vs the Japanese design that it got replaced with [2]
I suppose I should have thought of that—I'm wearing Japanese raw denim jeans right now—but I forgot all about fashion, so good point bringing that up. I don't know if there's much "you have to be in Tokyo" for, given the exportable quality of clothing, but it's a fair point on cultural output.
