Yes, the Narita Express (N'EX) is operated by East Japan Railway Company (JR East) and is fully integrated into the Japan Rail (JR) network. This is excellent news for travelers in 2026, as the service is 100% covered by the Japan Rail Pass. If you have an active JR Pass, you can ride the N'EX from Narita Airport to major Tokyo hubs like Tokyo Station, Shinjuku, and Shibuya for free. However, it is important to note that the N'EX is an "all-reserved" train; even with a JR Pass, you must obtain a seat reservation ticket from a JR ticket office or a "Reserved Seat" vending machine before boarding. The train provides a premium, high-speed connection featuring large luggage racks, complimentary Wi-Fi, and spacious seating, making it the most popular "JR-friendly" way to begin a trip in Japan.
