The “national dish” - curry-rice - is said to be eaten by many Japanese people once a week. It's more than 150 years since the Japanese came across this exotic dish that originated from India.
Curry came to Japan in the late 19th century. It was introduced by the British, initially as a luxury food, but in due course unique Japanese recipes were created that included meat boiled up with potatoes, onions and carrots, and it became popular as a nutritious meal. Subsequently, we came up with unique, Japanese flavors and curry-rice became a firm favorite in Japanese homes when, in 1963, a mild, instant curry for children came onto the market, replacing the traditional image of "hot curry." It then went on to be regarded as a national dish.
If you go to some special curry restaurants, you will get unique curry toppings.
