I can almost guarantee that if you haven't read the rest of this post your first reaction upon clicking that link will be to think I've lost my mind. The big ads for hot Japanese girls and hotels give it a particularly tabloid trashy look. What could be of interest here?
Quite a lot actually once your eyes adjust and you can focus on the text. Here you will find links to dozens of articles on just about everything Japanese, many of which are illustrated. Some are better than others, and most are drawn from other sources, but there is a lot of good information here.
Do you want to know how the Japanese celebrate Christmas? What a wedding kimono looks like? What is the climate like? Need a map of the country or of a particular city?
Here you go.
Anthony Bryant, A.K.A. Tony, A.K.A. Baron Edward of Effingham of the S.C.A., A.K.A. Eddie Effie, is the closest to a real life Miroku that I've ever met. He's a friend of friends and I got to talk to him once years ago when he came to visit. It was interesting to put a face to all their stories. Heh. I swear the man has more appendages than Naraku but somehow it's not possible to get mad at him. I found myself wordlessly removing his hand while continuing our discussion without a break.
The man knows his stuff about Samurai culture though. He has published history books as well as a source book for gaming in the feudal Japan. At this site you will find useful essays on Heian society, arms and armor, clothing, and links to other useful sites. The illustrations can be very detailed.
The site hasn't been updated since 2004 and some pages were only partially done at that time. Some of the entries have a picture and some text but also something like "Place holding text" or "Blah, blah, blah" indicating that he planned to add more to it. I'm hoping that he does, it's good stuff.
