The Narita Express (N'EX), which connects Narita International Airport to major hubs in Tokyo like Shinjuku and Tokyo Station, is not a 24-hour service. The train service typically begins its operations around 6:00 AM and concludes its final runs for the day shortly after 9:30 PM or 10:00 PM, depending on the specific destination station. This schedule is designed to align with the airport's flight arrival and departure windows, as Narita Airport has a strict midnight curfew for flights. If you arrive at Narita on a late-night flight past 10:30 PM, you will likely miss the last N'EX train and will need to rely on alternative transportation such as the Keisei Skyliner (which also stops around 11:00 PM), late-night limousine buses, or a very expensive taxi. As of 2026, there are no plans to make the N'EX a 24-hour service because the rail lines require nightly maintenance and inspections. Travelers with late-night arrivals should always check the live timetable on the JR East website or app to ensure they don't find themselves stranded at the airport after the final rail departures of the evening.
