You can use the Japan Rail (JR) Pass to cover a significant portion of the journey to Hakone, but it does not cover the entire trip. Specifically, you can take the Shinkansen (Bullet Train) from Tokyo or Shinagawa to Odawara Station using your JR Pass. From Odawara, you have entered the territory of the Odakyu Railway, which is a private company not affiliated with JR. To continue into the heart of Hakone (such as Hakone-Yumoto or Lake Ashi), you must purchase separate tickets or, more popularly, the Hakone Free Pass. In 2026, the Hakone Free Pass remains the best value for exploring the region, as it covers the mountain railway, cable cars, ropeway, and the pirate ship cruise. If you attempt to use your JR Pass past Odawara, the gates will not accept it. Most travelers use the JR Pass to reach Odawara for "free" and then switch to the local network, balancing the high speed of the Shinkansen with the specialized sightseeing transit that makes Hakone a premier destination.
