It is, I suppose, a chicken and the egg sort of thing, blended with a healthy dose of confirmation bias. Was Tokyo always a weird place? Or did people seek out weird things, and those things became popular, and thus the bizarre and the ludicrous in turn grew more profitable, more popular, more verdant and lushly crazy? If you go into Tokyo, Japan, seeking mainly to have the weirdest time you can, isn’t it just your own fault for then leaving and thinking of the place as, essentially, an enormous, metropolitan Wonka Chocolate Factory? The answer to many of these questions may be yes.
Which is a way of saying: my weekend in Tokyo was pretty weird, everybody. Just as I wanted.
