信州そば is a type of buckwheat noodle that originates from the Shinshu region in Nagano Prefecture, Japan. Known for its distinct flavor and chewy texture, these noodles are made primarily from locally grown buckwheat. The cool climate and pure water of the region contribute to the high quality of the soba. Typically served chilled with a dipping sauce or in a hot broth, 信州そば is enjoyed year-round. It is often garnished with green onions, wasabi, or tempura. This dish is not only a staple in local cuisine but also a popular choice among visitors to the area.
