No, you cannot practically walk between Terminal 1 and Terminal 2 at Narita International Airport. The two terminals are located quite far apart, separated by a significant distance and various airport infrastructure, including runways and service roads. There is no direct pedestrian walkway connecting them. Instead, the airport provides a free Terminal Shuttle Bus that runs frequently between all three terminals. The journey between Terminal 1 and Terminal 2 takes approximately 10 to 15 minutes depending on traffic. If you are in a rush or transferring between flights, the shuttle is the only viable option. While Terminal 2 and Terminal 3 are connected by a designated 630-meter walking track (access corridor), Terminal 1 remains isolated from the others, requiring motorized transport for any traveler wishing to switch between these specific wings of the airport.
