Spaghetti Napolitan（or, Neapolitan）sounds like Italian food from its name, but it is a quite Japanese food.
Spaghetti Napolitan is spaghetti pan-fried with ketchup.
Spaghetti Napolitan used to be a very popular food at restaurants and classic cofee shops in Japan. Now, you can eat it in "Yoshoku−ya", a western food restaurant where you can enjoy the traditional atmosphere and taste.
There are a few theories of how Spaghetti Napolitan originated. The strongest theory is that it’s originated in Yokohama during the post war. Around 1950s, a chef at the New Grand Hotel in Yokohama created this dish when he was inspired by one of the food served for the American military, which was spaghetti mixed with tomato Ketchup.
