I inserted a colon (:) since a list was being introudced. "Food from Japan" has the nuance that the the aforementioned foods originated/came from Japan, but can be/are also eaten elsewhere around the world. "Foods in Japan" means that the foods exist in Japan which is technically true, but we would use it to modify or be more specific about the cuisine. For example: "American food in Japan"=food from the US that is eaten/served in Japan. You can also use [X food] in [city] as well. An example is if I'm in Tokyo wanting Indian cuisine, I would type "Indian food in Tokyo" into the search bar.
