For those not interested in old Japan, this link probably means absolutely nothing, however, even if you're only partly interested in Japanese history (I am since I'm working on my feudal Japan - Kaidan setting) this is one of the most fascinating sites I've found online...

This site contains mostly photo postcards of Japan from the 1860's up to the 1930's, when photography first showed up in Japan, when it was opened to the world. Although Japan quickly modernized during this period, much of what was old Japan and now long gone away has been captured in these striking photos. Its one of my favorite sites on Japan at this time.

If you have any interest, its really worth checking out.

Enjoy!
