A rather nice site offering vintage photographic expositions on the Japan of the Meiji, Taisho and Showa periods comes to my attention; the prosaically named Old Photos of Japan offers a daily photograph along with some nice explanatory text putting the picture in context.
Many of the photos are extremely tasteful, so whether you’re a lover of Japan, history, photography, or perhaps even scantily dressed young ladies, you may do well to take a look.
