Japan National Route 139, National highway in Shizuoka and Yamanashi Prefectures, Japan
Japan National Route 139 is a national highway running 134.4 kilometers from Fuji City in Shizuoka Prefecture to Okutama in Tokyo. The road winds through mountainous terrain and connects regions with varying landscapes along its course.
The route was established in 1953 as part of national infrastructure development to connect Mount Fuji's surrounding regions with the Tokyo metropolitan area. This connection played a key role in opening up these rural areas for modern development.
Route 139 connects communities where residents keep old traditions and local festivals alive as part of daily life. Travelers passing through these towns can observe how these customs shape the character of each place.
The highway connects with several major routes, including the Tomei Expressway at Fuji interchange and the Chuo Expressway at Kawaguchiko interchange. Drivers should expect varying road conditions and elevation changes, especially during winter in the mountain sections.
The road offers drivers multiple elevation shifts that reveal different landscape types, from flatter sections to steep mountain passages. These changing scenes provide visual insight into the geographic variety of the Mount Fuji region.
