Ancient history[edit]

The area is part of ancient Mikawa Province.

Early modern period[edit]

Under then Edo period, Tokugawa Shogunate, much of what is now Hekinan was part of the holdings of Numazu Domain, with the remainder being tenryō territory under direct control of the shogunate.

Late modern period[edit]

Widespread rioting occurred in the area against the new Meiji government and its policy of shinbutsu bunri in 1871. The area was organized into towns and villages within Hekikai District by the Meiji period establishment of the modern municipalities system in 1889.

Contemporary history[edit]

Showa period

The towns of Ohama, Shinkawa and Tanao, and the village of Asahi merged on April 5, 1948, to form the city of Hekinan[2] As it is located on the southern (南) part of Hekikai District (海郡), the city was named Hekinan (碧南). Hekinan was the tenth city founded in Aichi Prefecture.[2] Since it had harbors and rails, the city developed quickly after Pacific War.

On April 1, 1955, one part of the village of Meiji, which is currently called Nishibata, was incorporated into Hekinan.

On September 26, 1959, Typhoon Vera also known as the "Isewan Typhoon" heavily damaged the city.

On July 14, 1974, Rinkai Kōen Pool or also known as Kinuura Mammoth Pool was opened.

Because the city reclaimed the seaside for industrial purposes in 1960's, Hekinan opened this pool for people who complained about losing their beautiful beach.

On May 23, 1988, Hekinan Municipal Hospital was opened.[6]

Heisei period

In 1993, Hekinan Thermal Power Station was created by Chubu Electric Power on the reclaimed ground. This provides high tax revenue to the city. On August 17, 2003, since the facility of the Rinkai Kōen Pool became old and the number of the visitors of the pool was reduced, the city shut down the pool. Instead, the city created Hekinan Rinkai Park on the same place.


Hekinan City Hall

Hekinan has a mayor-council form of government with a directly elected mayor and a unicameral city legislature of 22 members, which is considerably higher than other cities of similar size. The city contributes one member to the Aichi Prefectural Assembly. In terms of national politics, the city is part of Aichi District 13 of the lower house of the Diet of Japan.
