I've noticed that it is always us Asians that employ war crimes against Italian cuisine. Neapolitan spaghetti for another example. Although I do know one other asian who doesn't like pineapple pizza. He is dead to me.
But Naporitan is a Japanese dish inspired by the Italian cuisine, using Japanese ingredients and a vague idea of how an Italian dish is made. I think it can work since Japanese ketchup is actually more tasty than the average ketchup around the world. It's what you have at hand to create your own dish, and actually it works so well, like Vietnamese Bahn mi and such. Chicago Deep Dish is a goddamn blessing and is an adaptation.
Heck, even Italian cuisine is derived from these kind of adaptation: Chinese noodles brought by Marco Polo (that might be a legend more than a fact) and tomatoes from the New World. Not a single cuisine from any country is exempt from this kind of adaptations. It's what makes the world so vast and full of delicious dishes to be discovered!
This is why I never get angry when people bring the American taco, since a taco is a tortilla, soft or fried, filled with what you want or have. A savory stew, a grilled meat, some sausages, whatever you have in your country: cook it, put it in a tortilla and presto!
I'm certainly not one to complain about food as long as it is tasty (or I'm hungry enough), but I just can't get excited over that heresy spaghetti. It just tastes off over what it looks like it should taste.
