A survey by the Japan National Tourism Organisation says that foreign tourists visiting Japan enjoy sushi above any other national dish.

Four out of ten picked sushi -- morsels of vinegar-flavoured rice usually served with sliced raw seafood.
Ramen, a noodle soup that originated in China, came in second with 21 percent of visitors placing it top, just ahead of sashimi -- bite-sized slices of raw fish.
Tempura -- fish, shellfish or vegetables deep fried in batter -- was fourth and udon, a thick noodle made from wheat flour, was fifth.
