Yes, the journey between Osaka and Tokyo is fully included in the JR Pass, as it is part of the Tokaido Shinkansen line operated by Japan Railways. However, there is an important caveat regarding the type of train you can use. The pass covers the Hikari and Kodama trains for free; these take about 2 hours and 50 minutes. If you wish to take the Nozomi, which is the fastest service (2 hours 30 minutes), you must pay a supplemental fee in addition to your pass, a rule introduced after the 2023 price hike. In 2026, a 7-day Ordinary JR Pass costs ¥50,000, and the journey from Osaka to Tokyo is one of the most high-value redemptions available. The pass also covers local JR lines within both cities, such as the Osaka Loop Line and the Yamanote Line in Tokyo. To maximize the value of your pass, it is recommended to reserve your seat in advance at a JR ticket office (Midori no Madoguchi) or a ticket machine, which is also included for free with the pass.
