The Umaji Forest Railway, located in Umaji Village, Kochi Prefecture, is a tourist railway that inherits the history of the former Yarase Forest Railway. A replica diesel locomotive, scaled down to two-thirds the size of an original Porter steam engine, pulls passenger cars along the tracks. A standout feature of this railway is its commitment to sustainability: the locomotive runs on biofuel produced from used cooking oil collected within the village. The journey consists of two laps around a 300m course, offering a close-up view of the breathtaking nature surrounding the Nishitaniya River.
This region was once home to the Yarase Forest Railway, one of the largest forest railway networks in Japan. Developed during the Meiji and Taisho eras to transport forest resources, this network was vital to the area's development. By 1911, the tracks connecting Tano to Umaji were completed. Historically, the railway adapted to the rugged terrain using various methods, including gravity-based descents and even using animals like oxen and dogs to pull trolleys. Today, while its industrial role has ended, the railway preserves this history through a charming tourist experience.

The greatest highlight is watching the replica diesel locomotive in motion. The detailed design, mimicking a classic steam engine, is a treasure for railway enthusiasts and a way to connect with local history. The route follows the clear waters of the Nishitaniya River, allowing visitors to observe the harmony between the vintage-style vehicle and the natural environment. Furthermore, the use of biofuel highlights a modern, eco-friendly approach to preserving tradition.
The Umaji Forest Railway primarily operates on Sundays and public holidays. There are also limited runs on specific dates in April. Operating hours are from 8:30 to 16:30. Please note that service is highly dependent on weather; the railway may be suspended in the event of rain. While the scenery is beautiful in any season, it is essential to check the weather and the operational status before heading out.
Enjoy a relaxing, short loop through the forest while gazing at the scenic Nishitaniya River. The 300m course provides a peaceful moment to immerse yourself in nature. It is more than just a ride; it is an opportunity to learn about the historical significance of forest railways and the modern-day implementation of sustainable biofuel technology.
