Yunomae Line: The Scenic Railway of Kumamoto Prefecture
The Yunomae Line (湯前線, Yunomae-sen) is a picturesque railway route located in the Kumamoto Prefecture of Japan. Connecting Hitoyoshi-Onsen Station in Hitoyoshi to Yunomae Station in Yunomae, the line is operated by the Kumagawa Railroad (also known as Kumatetsu), a third sector railway company—a partnership between local government and private enterprise. As its name suggests, the line runs parallel to the scenic Kuma River, offering passengers a journey through the heart of the region's natural beauty.

History and Resilience
The Yunomae Line was originally opened in 1924 by the Japanese Government Railways. For decades, it served as a vital link for both passengers and cargo, though freight services were gradually phased out, ending beyond Taragi in 1974 and ceasing entirely by 1980. In 1989, the Kumagawa Railroad took over operations from JR Kyushu.
The line faced a catastrophic challenge on July 6, 2020, when torrential rainfall caused severe damage, including the total destruction of a major bridge over the Kuma River. This forced the suspension of all services. However, the commitment to the line's survival remained strong. In May 2021, it was officially announced that the railway would be restored, with a budget of approximately 4.6 billion yen. The national government funded 97.5% of this cost, with local governments covering the remaining 2.5%.
Recovery happened in stages. Services between Yunomae Station and Higo-Nishinomura Station resumed on November 28, 2021, following a series of trial and training runs. The final phase of restoration is scheduled for completion on September 20, 2026, when operations to Hitoyoshi-Onsen Station will resume. This restoration includes some infrastructure changes: Kawamura Station will be relocated and renamed Sagara-Toshima, and Higashi-Taragi Station will be renamed Taragi-Shōrenji.
Technical Specifications and Rolling Stock
The Yunomae Line utilizes a 1,067 mm gauge and operates without electrification, relying on diesel power. To manage traffic on the single-track line, the railway employs a token system: a tablet token is used between Hitoyoshi-Onsen and Asagiri, while a staff token is used between Asagiri and Yunomae. Asagiri Station serves as the sole location with a passing loop to allow trains to bypass one another.
The fleet has seen significant modernization. Between 2013 and 2014, the company introduced five new diesel cars designed by the renowned industrial designer Eiji Mitooka. While these modern trains were tragically inundated during the 2020 floods at Hitoyoshi Onsen Station, they remain a central part of the line's identity.

Financial Performance
Maintaining a rural railway presents significant economic challenges. Since its establishment as a third sector company in 1989, the Kumagawa Railroad's railway operations have struggled to produce an operating profit. For example, in fiscal 2011, the company reported operating profit losses of 120.76 million yen.
