In 2026, the JR EAST Travel Service Center at Haneda Airport Terminal 3 (International Terminal) typically opens at 6:45 AM and operates until 8:00 PM daily. This center is the primary location for tourists to exchange their Japan Rail Pass MCO (Exchange Order) for the physical pass and to make initial seat reservations. For those arriving outside these hours, an alternative is the Tourist Information Center in Terminal 2, which often has extended hours from 6:00 AM to 11:00 PM, though travelers must take the free shuttle or monorail between terminals to access it. If you arrive in the middle of the night, you will likely need to pay for a standard ticket to your hotel and visit a JR office at a major station like Tokyo, Shinagawa, or Shinjuku the following morning, as there is currently no 24-hour exchange service at Haneda.
