This guitar was made in Taiwan from 1983 to 1988 and retailed on release at 80,000 yen, this model appears
in the Yamaha Japan Archives but not in any western catalogues. It is likely that is was for sale in Japan only or maybe other parts of the far East.
Update August 2016 Whilst looking at some Ebay Japan listings I have seen one or two SA900s that are made in Japan as well as a couple that are Made in Taiwan. The serial numbers on two of the Japanese ones suggest 1984 and the pickup numbers on another suggest 1987 again showing that Yamaha were making the same guitar in two different countries at the same time.
I continue to see SA900 guitars made in Taiwan and Made in Japan dated from 1983 to 1988
