If you are referring to the San-in Main Line (which runs from Kyoto Station toward the Arashiyama area and beyond to the Sea of Japan coast), yes, it is fully covered by the Japan Rail Pass. This line is operated by JR West, making it a "standard" JR line. It is particularly popular with tourists who use the Sagano Line (a section of the San-in Main Line) to reach Saga-Arashiyama Station for the famous Bamboo Grove and Tenryu-ji Temple. The pass covers both the local trains and the Limited Express trains (like the Kinosaki or Hashidate) that run on these tracks. However, it is important to distinguish this from the "Sagano Scenic Railway" (the Romantic Train), which is a private heritage line and is not covered by the JR Pass. In 2026, the JR Pass remains a powerful tool for navigating Kyoto's outskirts, but travelers should remember that for travel within the city center, the subway and bus networks are private and require separate payment or an IC card like Suica.
