Bringing your own food and drinks onto the Shinkansen (Japan's high-speed "bullet train") is not only permitted but is a cherished part of the Japanese travel experience. Most travelers visit the station's "Ekiben" shops before boarding to purchase a regional Ekiben—a specialized bento box featuring ingredients and delicacies unique to that specific geographic area. Eating on the Shinkansen is considered perfectly acceptable because the seats are arranged in a forward-facing, airplane-style configuration with fold-down trays, unlike the lateral seating found on local commuter subways where eating is generally frowned upon. In 2026, many trains also feature a trolley service selling snacks, hot coffee, and even regional ice cream. It is customary to be mindful of strong odors and to take your trash with you when you disembark, disposing of it in the bins provided on the platform or near the train doors. Sharing a meal while watching the Mount Fuji landscape whiz by at 300 km/h is a quintessential Japanese "slow travel" ritual that provides a welcome contrast to the efficiency of the rail system itself.
