At Narita International Airport in 2026, you can exchange your Japan Rail Pass "Exchange Order" for the actual pass at several locations depending on your arrival terminal. In Terminal 1 and Terminal 2, the most common location is the JR East Travel Service Center, which is usually open from early morning (around 8:30 AM) until the evening. If the Service Center is closed, you can often use the JR Ticket Office (the "Midori-no-Madoguchi"), which typically has extended hours from as early as 6:30 AM to as late as 9:45 PM. These offices are located on the "B1" level of the airport, directly adjacent to the entrances for the JR train lines (the Narita Express). You must present your physical Exchange Order and your passport with the "Temporary Visitor" stamp to the staff. In 2026, it is highly recommended to check for any "holiday" closures, though these main airport hubs almost always remain open 365 days a year to accommodate international arrivals.
