What is the most popular subway in Tokyo?

The Takeaway: The most useful train line in Tokyo is the JR Yamanote Line, which is commonly called the "Tokyo Loop Line" or just "Loop Line." You can use a Japan Rail Pass on this line. The best way to pay for all trains and subways in Tokyo is with a prepaid Pasmo or Suica card.



While Tokyo has two major systems, the Tokyo Metro Tozai Line is often cited as the most "popular" in terms of sheer passenger volume and daily usage. However, if you include the JR lines that function as part of the subway network, the JR Yamanote Line is the undisputed king; it is the green circular "loop" that connects almost every major hub like Shinjuku, Shibuya, and Tokyo Station. In 2026, the Marunouchi Line remains a favorite for tourists and business travelers because it connects the capital's major commercial districts and is known for its high frequency, iconic red trains, and reliable, "on-time" performance.
