Yes, you can use the Japan Rail (JR) Pass to travel from Kansai International Airport (KIX) to various stations in Osaka. The most popular and convenient way is by taking the Haruka Limited Express, which provides a direct and comfortable connection from the airport to Tennoji or Shin-Osaka stations. For the Haruka, JR Pass holders can make seat reservations at no extra cost or use non-reserved cars. Alternatively, you can take the JR Kansai Airport Rapid Service, which stops at more stations like Kyobashi and Osaka Station (Umeda area) but does not require a reservation. In 2026, the Haruka remains a preferred choice for its speed and luggage space. It is worth noting that while the pass covers these JR-operated lines, it does not cover the Nankai Electric Railway (the "Rapi:t"), which is a private competitor also running from KIX to Namba. To use the JR Pass, simply present it at the manned ticket gate or use the automated gates if your pass is the newer magnetic version.
