Yes, you can absolutely use the Japan Rail (JR) Pass to travel from Tokyo to Kyoto, as this route is served by the Tokaido Shinkansen, which is operated by JR Central. The journey takes approximately 2 hours and 15 minutes on a high-speed bullet train. However, there is an important detail for 2026 travelers: while the pass covers the Hikari and Kodama trains for free, you must pay an additional "supplemental fee" if you wish to ride the Nozomi, which is the fastest and most frequent train on this line. Before the 2023 price hike, the Nozomi was completely excluded from the pass, but you can now use it by paying the upgrade at a ticket office. The JR Pass is highly convenient for this route because it allows you to hop on a train without purchasing a separate ticket, and the "Exchange Order" can be swapped for the actual pass at major hubs like Tokyo Station or Haneda/Narita airports. For a round trip between Tokyo and Kyoto, the pass provides excellent value, especially if you plan to use JR lines for local travel within Kyoto or for day trips to Nara or Osaka.
