The Keyboard Speciality shop you linked is great. It is always surprisingly crowded for such a niche topic. The have good test boards with different key switches.

Note that in the area are quite a few other good shops. Tsukumo has various hardware across many floors and also keyboards, in b1 they also have a razer store. Then there is a shop across the street Galleria or something, more targeting esports, if you are into that.
