Ramen, egg noodles in a salty broth, is Japan’s favourite late night meal. It’s also the perfect example of an imported dish – in this case from China – that the Japanese have made completely and deliciously their own. There are four major soup styles: tonkotsu (pork bone), miso, soy sauce and salt. Fukuoka is particularly famous for its rich tonkotsu ramen; pungent miso ramen is a specialty of Hokkaido.
