Fuji River
In 1926, the Minobu Railway Line connecting Kōfu with Shizuoka Prefecture opened, bringing an end to Fuji River transportation. The Koumi Line connecting Kobuchizawa to Kiyosato was opened by Japanese National Railways (JNR) in 1933, providing access to hitherto remote highland areas on the slopes of Mt. Yatsugatake in the North of the prefecture.
