Tokyo has so many people, it couldn’t avoid being one of the most diverse cities in the world. I guess the stereotype is that all 40M people are salaryman drones and housewives, but clearly that’s not true. If even half are something else, that still leaves tens of millions of people to fill out all the other varieties of people.
Whatever your culture or interest is, there will be a place you can find that in Tokyo, probably more so then any other city on Earth.
Au contraire. You'll find all sorts of people with different ideas, interests, curiosities, tastes, desires, opinions, vices and virtues; the full gamut of humanity, as you might expect in a metropolis of near 40 million.
Yes, certain traits predominate as they do in any culture but if you go looking I'm pretty sure you'll find what you're looking for in Tokyo.
