Soba (bulkwheat noodles) is one of the traditional Japanese food with hundreds of years of history, dating back to 300 B.C. when soba was consumed in non-noodle form like dumplings. Then it was cut into noodle form called soba kiri during the Edo Period (1603-1868). While there are many theories about the origin of soba but surely there is a record of soba kiri developed in Nagano Prefecture.
With the rich volcanic ash soil and the temperature range in highland, Nagano Prefecture has a vast area of wonderful natural environment for growing buckwheat and many other agricultural products. The Shinshu produced soba is considered one of the best in Japan.
If you go to tourism office and ask for recommendation for soba restaurant, the answer is: “They are everywhere. All good.” I stayed near the Nagano station, there are 2 soba restaurants in Midori shopping mall.
