The whole point of MIJ (if you ask me, anyway) is to offer quality + value.
Why? Is Japan a country with skilled craftsmen but cheap labour?
In a country where a single bell pepper will cost about £1.50 in an average supermarket and you can buy £100 watermelons (don't laugh), the salaries of the staff at Yamaha will no doubt be equally substantial.
Another sad point is that Japanese people tend to judge quality by price. If it's expensive it must be good,
and everyone wants the best.
In order to compete with Gibson, Fender and PRS, Yamaha probably has to inflate it's prices to gain credibility in the domestic market, and I'm sure they carry this policy over to the international market where the same rules don't always apply. Idiots.
Good design + High quality - any clue about marketing = YAMAHA
