Hmm, I'm not familiar with Koro, but I think I know the area you were referring to. The area where I took those photos is located close to Nippori, famous for its shrines, temples and its old Tokyo-style atmosphere. The area you're thinking of is actually another place which is located in an area called Kagurazuka, near the Imperial Palace. Actually quite an up-market area despite its Kyoto-esque appearance, well-known for having those similar looking backstreets, and yes, quite famous for a few having some nice restaurants, French ones if I'm not mistaken.
Cool little shop, huh? I actually discovered that shop on a backstreet surrounded by a few temples, believe it or not. There are lots of little old watch shops all around this '****a-machi' area. Great place to go watch hunting for vintage Japanese and the occasional Swiss timepieces (sorry no vintage G-Shocks...).That Seiko Jeweler looks a bit like the old jewelers you find here in the small towns. It looks like something between a living room and a shop. What is that man filling in that stand with all those Japanese texts?
