History of Soba, maybe longer than you imagine.

The cultivation of “Soba” or buckwheat in Japan started in Jomon period (about 10,000 BC – 300 BC). The first literature which describes “Soba” is “Shoku Nihon-gi” in Nara period (710-794). At first, people ate unground Soba just like rice. Even after milling technique enabled us to make Soba-ko (soba flour), people had “Sobagaki”, or buckwheat kneaded with (hot) water, for a long time. The noodle form was born in Edo period (1603-1867). It was called “Soba-kiri”. Various twists were added to “Siba-kiri” and it became so popular that it still remains.
