Yes, the Japan Rail (JR) Pass fully covers the journey from Tokyo to Kyoto on the Tokaido Shinkansen. However, since the massive price increase in October 2023, a standard 7-day pass (now costing ¥50,000) is no longer a guaranteed "money saver" for a simple round-trip between these two cities. A round-trip individual ticket from Tokyo to Kyoto costs approximately ¥28,000, meaning you would need to do significant additional long-distance travel to make the pass worthwhile in 2026. The pass allows you to use the "Hikari" and "Kodama" trains for free; as of 2026, you can also ride the faster "Nozomi" trains with the JR Pass, but it requires paying a supplemental "Nozomi/Mizuho Upgrade" fee for each segment. Within Tokyo and Kyoto, the pass also covers local JR lines (like the Yamanote Loop), but it does not cover the local city subways or private bus lines which are often necessary for sightseeing.
