This guitar was made in 1988 to 1991 and retailed on release at 90,000 yen according to Yamaha’s Japanese archives.
However they appear in Western Catalogues much later they were made in both Japan and Taiwan, possibly at different times.
They certainly appear in catalogues for 1994 in the west.
I have seen made in Taiwan models up to as late as May 1998 OH26307 is a Natural coloured January 1998 model and OL10111 is a black May 1998 model both MIT. In The March 2016 sale by guitar auctions there is an MIT SA 1100 dating from 1999 with the serial number PH05177 so is this the last year? Even more mysterious is that these guitars do not appear in any of the 1998 or 1999 catalogues.
Possibly the first run from 88-91 was Japanese and they made some from 1994 onwards in Taiwan, but this is just speculation.

A further complication is this guitar the serial Number should indicate a MIJ in 1986 which is two years before the launch, I would be inclined to believe that it is yet another Yamaha Serial Number anomaly. You would think that if it was MIJ they would have taken the photo at a slightly higher angle to show it.
Update January 2020
Alois Permaneder from the Yamaha forum has purchased a lovely 1100, which he points out is only 5 serial numbers away from one of the above guitars See pictures below. He has also pointed out that the strange serial number I show above may be SYJO001 which makes sense as a November 1988 model. Well spotted and good thinking. Thank you.
