If eating noodles first thing in the morning doesn¡¯t wake you up, the sound of other diners slurping certainly will. Soba buckwheat noodles and udon (chunky white wheat noodles) date back to the Nara (710-794) and Heian (794-1185) periods; ramen was introduced from China in the 1880s.

In Shikoku, famous for its Sanuki udon, noodles are eaten all day ¡ª including for breakfast. A good place to experience this noodle breakfast is Oniyanma, a shack near Tokyo¡¯s Gotanda Station that serves Sanuki udon with a light iriko (dried sardine) broth.

The U-shaped counter overlooks an open kitchen where noodles are boiled and battered ingredients are turned to tempura in a hot bath of oil. Roughly 10 customers can squeeze into the restaurant, and most mornings you¡¯ll be slurping shoulder to shoulder. Diners frequent Oniyanma for its unassuming, chewy noodles and the variety of toppings.
