A product of Japan. Purchased from Jappy11 on eBay. 

There's no mistaking the flavor of these chips.  When I opened the bag, I was hit with the smell of buttered roasted Red Bliss potatoes.  They're the best-smelling Doritos I know, and they don't taste too bad, either.  I'm more disappointed that Frito Lay doesn't take more chances with flavors in the U.S.
