KiHa 40 DMUs on the Yamaguchi Line
The KiHa 40 series diesel multiple units, introduced by Japanese National Railways in the late 1970s, remain in regular service on rural lines across Japan.
On the Yamaguchi Line—an unelectrified route linking Shin-Yamaguchi and Masuda—local trains are still operated entirely by these classic vehicles.
Finished in the iconic vermilion livery once known as the “Metropolitan Area color,” these trains evoke the atmosphere of the JNR era, both inside and out.
Their continued operation offers a rare opportunity to experience a largely unchanged form of everyday rail travel from decades past.
