The main purpose of the company that most are familiar with is the operation of the Semboku Rapid Railway in southern
Osaka Prefecture. The railroad starts at
Nakamozu Station on the
Nankai Kōya Line and ends at
Izumi-Chūō Station. During the 1960s, the Osaka Prefectural government planned a route link to Semboku New Town, one of many planned communities at the time of the post-war boom. The
Nankai Electric Railway was to undertake the total planning, construction and operation of the new route, but because Nankai had several large accidents in the later half of that decade, Japan's national railroad safety board forced Nankai to purchase new rolling stock and start restoration track and wayside equipment. Because of the required sudden investment, Nankai stalled on the Semboku line's construction timetable. The Osaka prefectural government, using an existing third sector company, stepped in to undertake the new railway's construction and operation. In addition to this, the original business as a logistics distribution center management body is still in operation. There are currently two truck terminals under its management in the following locations: •
Higashi Osaka commercial distribution center • Kita-Osaka commercial distribution center On 1 July 2014, the share of the company owned by the prefectural government was transferred to
Nankai Electric Railway and the company joined the Nankai Group. The company was expected to fold its operations into Nankai by 31 March 2025 On 1 November 2024,
Ministry of Land, Infrastructure, Transport and Tourism (MLIT) approved the merger, which took effect on 1 April 2025. ==Railroad route==
