Five Bridges of Amakusa (天草五橋, Amakusa Gokyō) are five road bridges at the south tip of Japan, linking the Kyushu mainland (Kumamoto Prefecture) and the Amakusa Islands. The bridges connect to the islands of Ooyano-jima, Nagaura-jima, Ike-jima, and Maeshima, and were completed on September 24, 1966. The Five Bridges gave hope and confidence in the development of Japan's bridge-construction technology, and changed the lives of those living at the Amakusa Islands (see survey below: Evaluation). Many tourists come to view the scenic beauty of the many islands, and the roads are called the Amakusa Pearl Line, based on the products of cultured pearls.

Significance
The timing of the completion of these bridges was good, as the popularization of automobiles in Japanese families started around the same year, with the launch of the Nissan Sunny 1000cc series and the Toyota Corolla 1100cc series, foretelling the so-called "My Car" age. The Five Bridges started as toll roads and were expected to continue for 39 years, but the explosive motorization collected tolls much faster, and ended the payment after nine years (in 1975).
Bridges
