A number of small alluvial plains are found in the corridor section. A mild climate, favorable location relatively close to the great metropolitan complexes, and availability of fast transportation have made this area a center for truck-gardening and out-of-season vegetables. Upland areas of rolling hills are extensively given over to the growing of mandarin oranges and tea. Nagoya, which faces Ise Bay, is a center for heavy industry, including iron and steel and machinery manufacturing. The corridor also has a number of small but important industrial centers. The western part of Tōkai includes the Nōbi Plain, where rice was being grown by the seventh century.
