Since prehistoric times rice has been grown and eaten in Japan, and because of its rich content of vegetable protein, carbohydrate, vitamins and minerals, it quickly became popular all over the country. By the 7th century it was firmly established as the staple food and has remained so ever since.
Japanese cooking really developed around rice. The plain, yet delicate and subtle flavour of rice made it possible for the Japanese people to develop an appreciation of the exquisite flavours and textures of other natural produce available to them.
