You do not seem to appreciate how regulation works in general in the United States. Product labeling is a perpetual game of cat-and-mouse. I can give you a litany of ways that vendors skirt the regulations, hide ingredients, lie to consumers, and falsify their labels while still remaining 100% legal. And obviously, I am not privy to all of their tricks, but just some of the obvious ones.

I do not know if the Utopian Japanese Food Industry* is so trustworthy and impeccable so as not to mislead customers or engage in malicious compliance. Perhaps they simply abide by the rules and manufacture honest food and inedible leaden paint chips. I don't know; Japan is the place where you can insert your whole rice into a streetside vending machine to have it robbed of nutrients... err, hulled and sifted.

Since I live next-door to a pan-asian market now, I will eventually figure out how they are labeling their sodas and snack foods. Thank you.
