The T?kai region (?, T?kai-chih?) is a subregion of the Ch?bu region and Kansai region in Japan that runs along the Pacific Ocean. The name comes from the T?kaid?, one of the Edo Five Routes. Because T?kai 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 Ch?ky? 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 Ch?ky? region.
T?kai 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.
The T?kai region has experienced a number of large earthquakes in the past, including the two great earthquakes in 1944 (also known as the "Tonankai earthquake") and 1945 (also known as the "Mikawa earthquake"). Following the work of Kiyoo Mogi, it is predicted that there is a possibility that the area will be subject to a shallow magnitude 8.0 earthquake in the near future.Nagoya, Shizuoka, and other large cities would be greatly damaged, with potential casualties in the tens of thousands. The Coordinating Committee for Earthquake Prediction designated the region as an Area of Specific Observation in 1970, and upgraded it to an Area of Intensified Observation in 1974.
Central Japan Railway Company, an arm of the former national railway Japan Railways Group, operates in an area roughly coextensive with the T?kai region. In fact, JR Central's legal Japanese name is T?kai Railway Company, abbreviated to JR-T?kai ("JR Central" is the English name). JR Central operates the T?kaid? Main Line between Atami and Maibara stations, as well as the T?kaid? Shinkansen high speed line between Tokyo and Shin-?saka, and many conventional lines joining with the T?kaid? Main Line.
The Hamaoka Nuclear Power Plant is located within the T?kai region.
