Yes, the Japan Rail (JR) Pass covers the Shinkansen (bullet train) journey from Tokyo to Kyoto, but it comes with specific restrictions regarding the type of train you can board. The JR Pass allows you to use the Hikari and Kodama trains on the Tokaido Shinkansen line for free. The Hikari is the most popular choice for pass holders as it is quite fast, taking about 2 hours and 40 minutes. However, the fastest train, the Nozomi, is not fully covered by the base price of the JR Pass. Since the late 2023 policy changes, JR Pass holders can now ride the Nozomi if they pay a supplemental "upgrade fee" for that specific segment, which costs around 4,960 yen. Without this extra payment, you must stick to the Hikari or Kodama. It is also important to note that seat reservations are free for JR Pass holders, and because the Tokyo-Kyoto route is the most traveled in Japan, it is highly recommended to book your seat a day or two in advance at a "Midori no Madoguchi" (Green Window) ticket office or via the official JR reservation app to ensure you aren't stuck in the non-reserved cars.
