According to reasearch, people ate buckwheat in about 7000 B.C. Also, seafood, nuts, animal meat, leaf buds, and plants were eaten. Rice was introduced to Japan about 400 B.C. during the Jomon Period. It became a staple food as it still is today. Soy beans, red beans, and wheat were introduced to Japan about 100 years later than the introduction of rice.
