The Narita Express (N'EX) is specifically designed for international travelers and offers ample, secure storage for large suitcases. At the end of each passenger carriage, there are dedicated luggage racks equipped with a sophisticated digital lock system. You can set your own four-digit code to secure your bag to the rack, providing peace of mind during the hour-long journey to Tokyo or Shinjuku. For smaller items like backpacks, carry-ons, or laptop bags, there are spacious overhead racks above every seat. In 2026, the N'EX remains the most comfortable way to transit from the airport because the seats are arranged in a 2-2 configuration with plenty of legroom, allowing you to keep a personal item at your feet if necessary. It is a "pro-tip" to remember your four-digit code, as if you forget it, you will have to wait until the train reaches its final destination and consult with a station attendant to have the lock manually released, which can be a significant delay.
