So I've just arrived in Tokyo for the first time and didn't bring rain boots in order to save on luggage weight / space. One look out this window and I see that's a fail.
I know I could just wander and probably run into a store selling rain boots, but I figured I'd ask -- if you were a person who cared more about not having wet socks than fashion, where would you go for rain boots in Tokyo?? Is there a recommendable store?
(I'm in Chuo-ku but am happy to take the train.)
