The JR Pass does not allow you to ride on subways or trams within cities. However, most big cities have a few JR lines that you can use to go around, like the Osaka Loop or Kanjo line and the Tokyo Yamanote line, for example.

The Japan Rail (JR) Pass does not cover the Tokyo Subway lines, which are operated by private companies like Tokyo Metro and Toei Subway. This is a common point of confusion for first-time travelers in 2026. The JR Pass is valid only on lines operated by the Japan Railways Group, such as the iconic green Yamanote Loop Line, the Chuo Line, and the Shinkansen. While you can reach many major hubs like Shinjuku, Shibuya, and Tokyo Station using only JR lines, reaching specific neighborhoods like Roppongi, Asakusa, or Ginza usually requires the subway. To navigate these, you should use a prepaid IC card like Suica or Pasmo (available on your smartphone's digital wallet) or purchase a separate "Tokyo Subway Ticket" for unlimited 24, 48, or 72-hour access. Since the massive JR Pass price hike in late 2023, it is a high-value strategy to calculate your total long-distance Shinkansen costs before buying the pass, as it is often cheaper to simply use a digital Suica for all travel within Tokyo.
