Tohoku is one of the five regions of the island of Honshu in Japan. The name Tohoku actually means "northeast" in japanese, and as the name suggests, it occupies the northeastern portion of Honshu.
Tohoku region comprises six prefectures namely Akita, Aomori, Fukushima, Iwate, Miyagi and Yamagata. It is a mountainous region with the Ou Mountains running north-south through the region. It was settled relatively late, in the 7th to 9th centuries, after the Japanese civilization has become firmly established in central and southwestern Japan.
The Tohoku region is the main supplier of rice and farm products to the populated areas of central Japan, including 20% of the rice output of the country. As the region experiences a harsh climate, only one crop of rice can be grown per year.
