This is a pretty old post that I didn't get round to finishing at the time - it actually refers to my first stay in Japan, in 2014!
Any location, in any town, has its quirks. My hometown is deeply peculiar (one might say dysfunctional, and be entirely accurate) and, though Fukuoka is a very different sort of place, I quickly discovered one of its (undoubtedly numerous) charming eccentricies: it appears to be the dentistry capital of the region, if not of all Japan. If I were antisocial enough to start slinging bricks around, a fair proportion would undoubtedly land on dentists. I started to feel hunted. Whenever I turned a corner, there, again, a dental clinic! Was I going round in circles (or, indeed, the bend)? Entirely misunderstanding some laughably-simple Japanese phrase that happened to appear on a wide range of businesses that were in no way dental clinics?
No.
