Frames in Japan seem pretty inexpensive when compared to US pricing, some of it due to exchange rates, some due to supply and demand.
My used Vivalo frame/fork in a hard to find 58x58 size was roughly $300 USD in Japan through the e-framebank Japanese friend hook-up... I can only imagine what the frame would go for on ebay right about now with "commonly" available 52-55cm frames fetching $700+. I'm guessing new frames are subject to markups in teh same range.
