Where would the demand for good food airside be at an international focused airport like Narita?

Premium passengers have lounges, so the food would have to be markedly better to get these passengers to leave their lounges and decent free food (and the ANA Suite lounges have been stepping up their game).

We’re left with economy passengers then, who are more price conscious (which correlates to lower quality of food). Japanese citizens and residents can just eat before going to the airport, which will both be cheaper and better tasting, so we really only have international economy passengers.

That, combined with the fact that Narita is so far away from most people would live, doesn’t make for a compelling business case.
