What Is the Shinkansen?

The Shinkansen is Japan's high-speed rail network, running since 1964. These trains reach speeds of 260–320 km/h and connect cities across the country. Think of it as Japan's equivalent of flying between cities — except it's more comfortable, departs every few minutes, and arrives right in the city center.

The average delay across the entire Tokaido Shinkansen network? Under 1 minute per year. Yes, per year. It's that reliable.

Main Shinkansen Lines

Here are the lines you're most likely to use as a tourist:

The Tokaido Shinkansen (Tokyo–Kyoto–Osaka) is by far the most popular with tourists. If you're doing the classic Tokyo–Kyoto trip, check our detailed Tokyo to Kyoto bullet train guide.

Seat Classes Explained

There are three types of seats on most Shinkansen trains:

🪑 Unreserved (自由席 / Jiyū-seki)

The cheapest option. Hop on any unreserved car and grab an open seat. Great for flexibility — you can take any departure. The downside? During rush hours or holidays, you might have to stand. Cars 1–3 are typically unreserved.

💺 Reserved (指定席 / Shitei-seki)

About ¥530 more than unreserved. You get a guaranteed seat on a specific train. This is what most travelers book, and it's what we recommend for longer journeys. During peak periods (Golden Week, Obon, New Year), always go reserved.

🟢 Green Car (グリーン車 / Gurīn-sha)

Japan's equivalent of first class. Wider seats (2+2 instead of 3+2), more legroom, footrests, and quieter cars. Costs roughly 30–50% more than reserved. Nice to have, but honestly, regular reserved seats are already very comfortable.

If you're making multiple long-distance trips, a JR Pass could save you a lot. Check our complete JR Pass guide for 2026 to see if it's worth it for your itinerary.

How to Buy Tickets

At the Station

• Ticket counters (みどりの窓口 / Midori no Madoguchi): Staffed counters where you can buy tickets in English. Look for the green signs. Available at all major stations.
• Ticket machines: The green ticket machines have English menus and accept credit cards. Faster than the counter once you know what you're doing.

You can buy tickets on the same day — no advance booking required. Just show up and go.

Online / App

• SmartEX: The official app for Tokaido/Sanyo Shinkansen. Book and pay on your phone, then tap your IC card or phone at the gate. Sometimes offers early-bird discounts. Highly recommended.
• EX-IC: Similar to SmartEX but requires a Japanese credit card. Most tourists will use SmartEX instead.
• Eki-net: JR East's booking platform for Tohoku, Hokuriku, and other eastern Shinkansen. Recently became more foreigner-friendly.

Oversized Baggage Rules

Since May 2020, the Tokaido, Sanyo, and Kyushu Shinkansen require a free reservation if your luggage exceeds 160 cm total (length + width + height). These bags go in special spaces behind the last row of each car.

• Under 160 cm total: No reservation needed. Use overhead racks or the space in front of your feet.
• 160–250 cm total: Free, but you must reserve an "oversized baggage seat" when booking your ticket.
• Over 250 cm total: Not allowed on board.
• Penalty for no reservation: ¥1,000 fee if you bring oversized luggage without reserving.

Most standard suitcases (up to about 28 inches / 71 cm) are well under 160 cm total. You probably don't need to worry unless you're traveling with massive bags.

Etiquette Tips

The Shinkansen is famously quiet and orderly. Here are the unwritten rules:

• Keep your voice down. Phone calls are a big no — step to the area between cars if you need to talk. Conversations should be at a low volume.
• Eating is totally fine! Grab an ekiben (station bento box) for ¥800–1,200. Eating on the Shinkansen is a beloved Japanese tradition. Just avoid strong-smelling foods.
• Recline your seat gently. A small nod to the person behind you before reclining is appreciated (not required, but nice).
• Keep your luggage tidy. Don't block the aisle. Use overhead racks or the space behind the last-row seats.
• Line up on the platform. Follow the floor markings showing where doors will open. Queue in an orderly line.
• Don't rush the doors. Trains stop for only 1–2 minutes at stations, but that's plenty of time. Stay calm.
• Clean up after yourself. Take your trash with you or use the bins at the front/rear of the car.
