People in the Edo period(1603-1868) thought drinking sake at a soba buckwheat noodle restaurant was the best. Kawasaki-an loved the idea and started its business to realize such culture in the present day. They provide a modern and stylish atmosphere that overturns the typical soba restaurant. Its main shop is in Karuizawa, Nagano, which is Japan's leading highland resort located in Nagano prefecture at an altitude of 900 to 1,000 m.

Kawakami-an carefully selects buckwheat flour and roughly grinds them with a custom-made stone mill. They provide Nihachi Soba(80% Buckwheat Flour, 20% Wheat flour) with a spicy soup. Since they came from Nagano, you can enjoy the excellent line-up of Shinshu's sake and wines as well.
