This is a historic Japanese village.
Its not far from Aizuwakamatsu. Some people arrived by taxi, I'm guessing from the nearby railway station.
It was just a little bit busy when we were there, but not overly crowded.
At least in winter the houses were mostly pretty closed up to keep the cold out. We'd recommend going into one of the restaurants to eat since they are nicely decorated inside aswell. Perhaps in summer you can see inside more easily.
There is a hill behind the town where you can go to get a view over the town.
