I love wandering around the old neighborhoods of Japanese towns and villages. All these photos are from one of the old parts of the castle area in Hamada.
There are usually a mishmash of architectural styles and periods. The photo above is probably Meiji era, and was probably a school originally.
The area south of the castle had an awful lot of "Snacks", or Sunaku, little drinking establishments that don't serve meals, just alcohol and "bar snacks" and in some instances female companionship.
I counted at least 30 within a few hundred metres of walking back streets. Most of them kind of funky.
There were also a lot of temples, many of them quite picturesque, with statues, and gardens etc
I'm not sure if there is a direct relationship between a neighborhood having a lot of temples and a lot of bars :)
There is a lot of history in these neighborhoods, and not the contrived museum kind of history one finds in tourist areas, and perhaps more interesting because of that.
