Tōhoku region
Tōhoku was traditionally considered the granary of Japan because it supplied Sendai and the Tokyo-Yokohama market with rice and other farming commodities. Tōhoku provided 20 percent of the nation's rice crop. The climate, however, is harsher than in other parts of Honshū due to the stronger effect of the Siberian High, and permits only one crop a year on paddy fields.
Erimo, Hokkaido
While the main industry is fishing (salmon and squid in particular), Erimo's most famous harvest is kelp which is harvested by most of the native residents during the summer months. The kelp is sold in Japan as Hidaka "konbu", and Erimo has a museum in the main part of town dedicated to kelp and fishery.
