No, the Japan Rail (JR) Pass does not cover the Metro or any private subway lines in cities like Tokyo, Osaka, or Kyoto. The JR Pass is exclusively for use on the Japan Railways (JR) Group network, which includes the Shinkansen (bullet trains), limited express trains, and local JR commuter lines. In Tokyo, you can use the JR Pass for the Yamanote Line (the famous green loop) and the Chuo/Sobu lines that cut across the city, but you cannot use it for the Tokyo Metro or Toei Subway lines. Similarly, in Kyoto, the pass works for the JR line to Arashiyama but not for the city's municipal subway. To navigate these non-JR systems in 2026, travelers typically use an IC Card (like Suica or Pasmo) or purchase a separate "Tokyo Subway Ticket" for 24, 48, or 72 hours. While the JR lines are extensive and can get you near most major landmarks, the Metro is often more convenient for "fine-grained" city travel, meaning most visitors will need to supplement their JR Pass with local transit fares.
