The top part is Japanese, the middle is Chinese, and the bottom is Korean. In the Japanese, there's a part that says "原産国名:アメリカ", which means "Country of Origin: America". Below that there's a part that says コストコホールセールジャパン, which says "Costco Wholesale Japan". Then in the Korean there's a part that says "KELLOGS OMAHA PLANT" in English.

Asia can't grow corn worth a shit. They import a ton of their corn products. This is just something made in the U.S. (I'm surprised too) and they slapped a couple nutrition labels on it so they can export it over to Asia and sell it there at their Costcos. Grocery Outlet probably just got them cheap because it's wholesale designed for Asia.
