Japan had a very strict foreign policy until around 1866. Once the policy was lifted Japan started trading with foreign countries. Through these interactions with the West, new ideas for food emerged. Japanese recreated these newly introduced food ideas and categorized them as“Western foods.” Although they were Western-style foods, Japanese people created these foods as an interpretation of the dishes and not as an exact replica. You wouldn’t be able to find Omurice all over the West. It is a Japanese dish, with a westernized style.
