FYI, although they may not be as hot as a nagasawa, samson, 3rensho, etc., you can get a brand-new panasonic (NJS) for 74,000-yen with custom colour/stencilling, sizes 460-630mm. i expect you will need to order it to a local address, then ship it back home, if you were interested.

i have never ridden one, so i can not comment on the ride/feel.
