You can buy noodles on just about every street corner in Tokyo. Shops serve a variety, including soba (buckwheat noodles served hot or cold), udon (fat, white noodles), ramen (actually these are Chinese noodles, but still very popular in Japan), yakisoba (fried noodles), or somen (cold summer noodles). Noodle shops are great for quick meals and are generally inexpensive.
Noodles serve as the basis for dishes such as yakisoba (though the noodles resemble ramen more than soba), which is a friend noodle dish containing meats and vegetables. Noodles also make an appearance in sukiyaki and other dishes.
