Explore the appeal and charm of the Koumi line with railroad photographer Hiroshi Sakurai
A short and compact trip of just over 2 hours.
When departing from the in 2017 rebuild station of Kobuchizawa, the Yatsugatake mountains can be seen on your right and the Southern Alps on your left. Soon, the train will slowly make a wide curve between surrounding rice paddies towards the Yatsugatake and starts climbing. On a nice day the Yatsugatake range will stand out against the blue sky. This beautiful view at the beginning of the journey is heartwarming. Soon the train will enter the forest, traversing large and small valleys. The Yatsugatake shows itself between larch, white birch and broadleaved trees, the many summer houses and small pensions, meadows and highland vegetable fields. From narrow openings between Kai-koizumi and Kai-Ozumi stations you will be able to see Mt. Fuji.
The mountains after Nobeyama station to close-in on both sides. The end of a tunnel you pass through leads you into a valley and source of the Chikuma river. The sparkling river shows on you left hand. Further on, the landscape is dotted with old storehouses, rice fields and private residences. The train will cross the river multiple times keeping the river onetime on the left, other times on the right. At times the reflecting light will turn the water a deep blue.
Just about an hour after departure from Kobuchizawa, the landscape gradually changes into fields. In front of you Mt. Asama will loom in the middle of the flat rural scenery of Saku Daira.
The splendid scenery of the rice paddies changes with the seasons from mirror-paddies in spring, to summer green-paddies in, to golden in autumn.
While the train gradually returns to residential territory, the number of commuters and students increases, and the train becomes livelier. When nearing Komoro, the end of the line, it is hard to imagine that just shortly before you were traversing the highlands at an altitude of more than a 1000 meters, and crossing deep valleys.
After about 2 hours and 10 minutes the train reaches the end station.

Japan’s highest railroad
Get a taste of the different enjoyments
“The best point of the JR railways is easily between Kiyosato and Nobeyama” where the Koumi line traverses the highest trajectory in Japan”, says the railway photographer Hiroshi Sakurai, who published a monthly series of 18 books, and communicates about the appeal of railroad trips around the world on TV and in publications. Furthermore, Mr. Sakurai lists a variety of tasty Ekiben (Station lunchboxes) that can be found at Kobuchizawa station, and the hybrid diesel train which was the first to be introduced in the world, as points of interest.
“But I think that just traveling by train could be enjoyable too.”, he says.
“One such example is the Koumi line trip. I think that enjoying the different characteristic landscapes such as highlands, valleys, and country side is one of the main appeals of traveling by train in Japan.” However, is it not because Mr. Sakura is such a fan that he thinks that “Just riding a train” would be enough to have fun?
“I also drive a car, however, the pleasure of riding on a train is very different from driving a car.
When taking a railroad trip, the amount of luggage you can bring is limited, and in a sense, you become one with nature, urban areas and farming areas—entering different locations.
Furthermore, there are many things you can not do when traveling by car: dozing off, reading, or eating to name a few. While traversing the highlands one can enjoy a lunchbox prepared with highland vegetables, or taking photos, which is only possible when riding on a train.
Please, enjoy respectively time and space when taking the Koumi journey”.
