Historical Evolution

The history of the Ōmura Line is deeply intertwined with the development of Japan's national rail network. Originally opened by the Kyushu Railway Co. on 20 January 1898, the entire route initially functioned as part of the Nagasaki Main Line. Following the nationalization of the company in 1907, the line continued to serve as a primary artery for the region.

A significant shift occurred in 1934 when a new section of the Nagasaki Main Line opened between Hizen-Yamaguchi (now known as Kōhoku) and Isahaya. This development led to the official renaming of the existing route as the Ōmura Line. In more recent history, the line saw technical upgrades in 1992, when a 4.7-kilometer section between Haiki and Huis Ten Bosch was electrified using 20 kV 60 Hz AC overhead lines to support operations for the Huis Ten Bosch theme park area.
