This is a nothingburger. (Nothingpizza?)
It's much better than Domino's in the US if you are commenting on Domino's in general.
It likely has nothing to do with production but rather with sourcing - shitty components are not readily available in Japan as they are in the US.
Quality of chain food is usually down to how fresh it is, mostly from high turn over, and workers actually caring. Some of it is culture, but I taught college kids and many of them expected and got promotions to manager or corporate after working part time jobs during college.
Pizza in Japan usually sucks unless it's Italian style because they can't charge a premium on specialty buffalo mozzarella cheese and it's hard to get anything else of quality in bulk. I've had the discussion with Japanese living abroad about how there are obviously lots of dairy farms in Hokkaido producing quality milk and butter, but everything else is over priced and/or terrible. Pizza Hut, Domino's, and Costco can use their global sales to import or buy domestic in bulk. Sometimes the chains completely rework the product for the market. Domino's and KFC basically taste nothing like their US version. McDonald's is the same just often times fresher
Ghost Kitchens have come full circle at this point, and many eateries with independent delivery can't maintain it.
Delivery customers today are asking why maintain a separate account, app, and loyalty to the one, when even the custom apps proliferate.
There are other pizzerias that serve my location, but prices would go up if competition disappears.
