Okay, I guess the model name
is "MR." I have been digging and digging on Google and can honestly only find
one example of this bike posted by someone in Japan. It's a pretty sweet road conversion:

It has some higher-end parts on it than the one I posted above, obviously. Oh yeah, I spotted a blurry Deore LX rear derailleur in my photo, which I guess is a higher-end product than the STX on my bike now.
