Tōkai region

The Tōkai region (東海地方, Tōkai-chihō) is a sub-region of the Chūbu region in Japan that runs along the Pacific Ocean. The name means "East sea" and comes from the Tōkaidō, one of the Edo Five Routes. Because Tōkai is a sub-region and is not officially classified, there is some disagreement about where exactly the region begins and ends, however Japanese maps widely conclude that the region includes Shizuoka, Aichi, Gifu and Mie prefectures.

The largest major city in the region is Nagoya and the Chūkyō Metropolitan Area (Nagoya Metropolitan Area) makes up a large portion of the region and has Japan's third strongest economy. The business influence of this urban area sometimes extends out into the outlying areas of the three prefectures centered on Nagoya which are Aichi, Gifu, and Mie; this area is sometimes referred to as the Chūkyō region.

Tōkai is a heavy manufacturing area and is one of the most industrial regions in Japan. Its coast is lined with densely populated cities with economies that thrive on factories.
