While the Shinkansen is famous for its punctuality and efficiency, you should generally aim to arrive at the station 15 to 20 minutes before your scheduled departure if you already have a ticket. If you need to purchase or pick up a ticket from a vending machine or the "Midori-no-madoguchi" (ticket office), you should allow 30 to 45 minutes, especially at major hubs like Tokyo or Shin-Osaka where queues can be long. In 2026, many travelers use QR code tickets or IC cards (like Suica) linked to apps like Smart EX, which allow you to head straight to the gates. It is important to note that Shinkansen doors close exactly at the departure time, and the trains do not wait. If you have oversized luggage that requires a specific reservation (common on the Tokaido, Sanyo, and Kyushu lines), arriving early ensures you can find your designated storage area or car without rushing through the crowded platforms.
