Izumo Soba: Shimane's Three-Tiered Buckwheat Noodles

Izumo soba, centered on the city of Izumo in Shimane, is often named as one of Japan's three major regional soba traditions, alongside styles from Nagano and Iwate. It's made by milling the buckwheat groat whole, including parts of the husk, which gives the noodles a darker color, rougher texture, and stronger buckwheat flavor than the refined, pale soba more common elsewhere in Japan.

The signature serving style is warigo soba: cold noodles served in two or three stacked round lacquered bowls rather than one plate. You pour dipping sauce, often a slightly sweeter, darker soy-based sauce than standard soba tsuyu, directly over the noodles in the top bowl, eat, then pour any remaining sauce into the next bowl down, adding more as needed. It's a communal, slightly playful presentation built for repeat helpings.
