Small grain, big aroma
Zairai means native. Kanuma's buckwheat grains are only about 80% the size of ordinary ones, 3.8 to 4.2 mm. The husk is thin, so more of each grain is the inner skin that carries buckwheat's aroma. The noodles taste clean and gently sweet thanks to plenty of starch, and lower protein gives them a crisp, clean bite.
Too poor for rice
The land around Kanuma city, Tochigi, was too poor for rice, so people have grown buckwheat since the Edo period, and soba became part of daily life. The area lies at the southern foot of the Nikko mountains, where warm days and cold nights build sweetness in the grain.
Kept pure in hidden valleys
To stop it crossing with other buckwheat, growers choose fields in valleys cut off from each other by hills, and that has kept the native strain alive.
Good to know
- Kanuma's autumn festival in October, with its carved wooden floats, is on UNESCO's Intangible Cultural Heritage list.
- Kanuma is on the way to Nikko. Stop for soba on a day trip from Tokyo.
- Compare with Sanbe Soba, another native buckwheat from Shimane.
