Sanuki udon (讃岐うどん) is an udon noodle dish most popular in the Kagawa prefecture in Japan, but is now easily found throughout the neighboring Kansai region and much of Japan. It is characterized by its square shape and flat edges with rather chewy texture, and in an authentic sense, ingredients should be from among those local specialties as wheat flour, Niboshi dried young sardines to cook broth for soup and dipping sauce. Many udon shops now specialize solely in sanuki-style chewy udon, and are usually identified by the text "sanuki" in hiragana (さぬき) appearing in the name of the shop or on the sign.
