Don’t you think Champon is a Korean cuisine? Certainly Korean-made Champon is sold at the super market in the Philippines. There might also be TV commercials about it.
But, Champon is traditional Japanese food. The birthplace is Nagasaki where famous for A-bomb survivors. “Champon” is Japanese meaning “Mixture.” It is common to have thick noodles, mixed chicken roe soup and pork soup, plenty of fried vegetables, fish paste, cloud ear mushroom and so on.
In recent years, Koreans adjusted it to Korean style and sold it. Therefore Korean Champon is pretty spicy, but the original Champon is a dish featuring sweetness of vegetables.
You can enjoy the Champon in a restaurant chain named Ringer Hut in Japan.
