Train Details

This train provides service along the Koumi Line, which has many attractions, such as the panoramic views of Mount Yatsugatake and other mountainous terrain, bountiful harvests from the long days and extreme temperature differences, and excellent nighttime star-gazing.

Origin of the name

The Koumi Line, which connects Kobuchizawa Station in Yamanashi Prefecture to Komoro Station in Nagano Prefecture, also known as the Yatsugatake Kogen Line, runs at the highest elevation of any Japan Railways line. This train was named HIGH RAIL 1375 in order to highlight the high elevation of the Koumi Line, which has the highest section of “RAIL” of any JR Line at 1,375 meters above sea level, between Nobeyama and Kiyosato stations. The name was chosen in the hope that visitors will enjoy how starry the sky is when seen from the high elevation of the Koumi Line.

Design

Exterior

Inspired by the night sky of the Koumi Line and the flow of the Yatsugatake Mountains seen from the train window, the design uses the metallic texture of the train body as a canvas. For adults, the exterior design evokes a sense of setting off on a lightly nostalgic journey while for children the effect is that of embarking on an exciting adventure.

Interior

With features such as seats and logo designs inspired by the stars of the four seasons, metallic riveted window frames, and artistically decorated blackboard-like walls – the elaborately decorated interior adds excitement to your trip.
