Matsumoto san,
Domo arigato gozaimasu! That's a very interesting website. I don't read Japanese very well so I'm sure it will give me hours (and hours, and hours, and hours) of enjoyment with my denshi jiten. A fellow with the Axis discussion group sent me this link:

which might interest you. It's in Russian and I read Russian even more poorly than Japanese. Speaking of reading Japanese... this photo was on the ostpanzer website:
The most I can get from it by glancing at it is that the photograph was taken outside of Nanking in December of 1937 and that it was a cameraman from the Osaka Maenichi Shinbun. Can you help me with a basic translation? The characters are a bit too small for me to make most of them out clearly.
Again, thanks very much for the information.
yoroshiku,
Pat
