Choosing a Shinkansen seat isn’t just a small detail—it can change how comfortable, quiet, or scenic your journey feels. The three decisions that matter most are simple: window or aisle, reserved or unreserved, and ordinary car or Green Car.
Most travelers can make the right choice in under two minutes once they understand how the system works. For anyone using a Japan Rail Pass, reservations are free, which removes the cost barrier to picking a specific seat.
Here’s what you need to know before booking: in ordinary class, A and E are the window seats; in the Green Car, A and D are the window seats. Reservations are free for JR Pass holders and recommended for peak travel.

Is the Window Seat Better on the Shinkansen, and How Do I Choose a Seat? — Quick Answer
A Shinkansen window seat is best for scenery and privacy, especially on routes like the Tokaido line where Mount Fuji is visible. In an ordinary class, window seats are A and E (3+2 layout), while in a Green Car, they are A and D (2+2 layout). Reserved seats guarantee a specific seat, while unreserved seats are first-come, first-served; both are covered by the JR Pass, and reserving is recommended during busy periods.
Is the Window Seat Better on the Shinkansen?
There’s no single “best” seat. It depends on your priorities.
Window seat advantages
- Access to views (Mount Fuji, coastline, rural landscapes)
- More privacy from passing passengers
- A surface to lean against for rest
Aisle seat advantages
- Easier access to restrooms and luggage
- Faster exit at busy stations
- Slightly more flexibility to stretch into the aisle
Middle seat (B in ordinary class)
This is the least desirable option. No window, limited space, and awkward positioning between two passengers.
For shorter trips (Tokyo to Osaka), either option works. For longer journeys (Tokyo to Hakata), aisle seats often become more practical.
If you’re specifically traveling for views—like Mount Fuji—the window seat matters. The exact side of the train determines what you see, which is covered in more detail in guides focused on Mount Fuji viewing routes.
Shinkansen Seat Letters Explained
This is the part that matters most when you’re on a booking screen.
Ordinary Class (most trains)
Layout: 3 seats on one side, 2 on the other
- A: window
- B: middle
- C: aisle
- D: aisle
- E: window
Green Car (first class)
Layout: 2+2
- A: window
- B: aisle
- C: aisle
- D: window
Gran Class (premium)
Layout: 1+2
- A: window (single seat)
- B: window
- C: aisle
On the Tokaido Shinkansen (Tokyo → Shin-Osaka), the ABC side is on the left, and DE is on the right. That means seat E is the right-side window, which matters if you’re aiming for views.
The key takeaway: the seat letter doesn’t change, but the scenery relative to that seat depends on direction.
Reserved vs Unreserved Seats
This decision often matters more than window vs aisle.
Reserved seats (指定席)
- Assigned seat at booking
- Guaranteed availability
- Small fee for regular tickets (¥320–¥530)
- Free for JR Pass holders
Unreserved seats (自由席)
- No assigned seat
- First-come, first-served
- Risk of standing during busy periods
- Free for JR Pass holders
On busy days, such as weekends, holidays, and cherry blossom season, unreserved cars can fill completely.
The practical rule is simple: if you have a Japan Rail Pass, always reserve. There’s no cost, and it removes uncertainty. The only reason to choose unreserved is flexibility when you want to board any train without planning.
Some trains, like Hayabusa or Kagayaki, are fully reserved, with no unreserved option.
Ordinary Car vs Green Car
The difference is comfort and space.
Ordinary Car
- 3+2 seating layout
- Standard legroom (~104 cm seat pitch)
- Comfortable for most journeys
- What most travelers use
Green Car
- 2+2 seating layout
- More legroom (~116 cm)
- Wider seats and deeper recline
- Quieter atmosphere
Gran Class
- 1+2 seating
- Full recline, premium service
- Requires an additional supplement
For shorter trips (Tokyo–Osaka), ordinary class is usually enough. For longer journeys (Tokyo–Hakata or Tokyo–Aomori), Green Car becomes more noticeable.
What Row Has the Most Legroom on the Shinkansen?
If legroom matters, seat position matters more than class.
Front row (Row 1)
- Faces a bulkhead
- Often has extra legroom
- Space varies depending on the train
Last row
- Also near a bulkhead
- Adjacent to the oversized luggage area
- Requires a separate luggage reservation
Aisle seats
- Offer slightly more room to extend your legs
For taller travelers (over 185 cm), the ordinary class can feel tight regardless of row. In that case, Green Car becomes a more meaningful upgrade, especially on longer trips.
The luggage area rules, especially for oversized baggage, are explained in more detail in guides covering Shinkansen luggage policies.
How to Reserve a Shinkansen Seat
There are three main ways to reserve.
JR Pass holders
- Online reservation systems: Seats can be reserved through official JR websites before arriving in Japan or once your pass is activated.
- JR ticket offices (Midori no Madoguchi): Staff can assist with reservations, route planning, and seat preferences in person.
- Ticket machines at major stations: Many machines support English and allow quick seat selection without waiting in line.
Reservations are free for JR Pass holders and can be made one month in advance. It’s often best to reserve as soon as your travel dates are confirmed, especially for popular routes.
Paper-ticket travelers
- Same process: Reservations can be made online, at ticket offices, or via machines.
- Reservation fee: A small fee is included in the ticket price when selecting a reserved seat.
Booking window
- Opening time: Reservations open one calendar month before departure at 10:00 AM JST.
- Peak periods: Holidays, weekends, and cherry blossom or autumn seasons sell out quickly.
- Off-peak travel: Seats are usually available even a few days before departure.
A few practical steps can make the process smoother:
- Plan your route first: Decide your departure time and train type before reserving.
- Choose your seat early: Window seats and Mount Fuji-side seats are the first to go.
- Have a backup train: If your preferred departure is full, nearby departures are often available.
- Check luggage rules: Oversized luggage requires reserving specific seats at the back of the car.
Many booking systems show seat maps, allowing you to pick your exact seat: window, aisle, front row, or otherwise.
Can I Change My Shinkansen Seat Reservation?
Yes, and it’s easier than most people expect.
JR Pass holders
- Unlimited free changes: Reservations can be modified as many times as needed before departure.
- Flexible options: You can switch trains, change departure times, or select a different seat.
- Access points: Changes can be made online, at ticket offices, or using station machines.
Paper tickets
- First change: The initial modification is usually free if done before departure.
- Additional changes: Further adjustments may incur a small fee depending on the ticket type.
If you miss your reserved train, you can usually board the next one in unreserved cars without extra cost.
A few practical considerations:
- Make changes early: Popular trains can fill up quickly, especially during peak travel periods.
- Check train types: Switching from Nozomi to other services may affect travel time or seat availability.
- Keep tickets handy: You may need to scan or present them again when updating reservations.
A practical approach: reserve early to secure a seat, then adjust later if your plans shift.
Practical Tips for Choosing a Shinkansen Seat
This is where everything comes together.
- Mount Fuji views: Book seat E on Tokyo → Shin-Osaka or seat A on the return journey.
- Long journeys: An aisle seat is often more comfortable for easier movement during the trip.
- Tall travelers: A front or last row seat provides extra legroom, or consider upgrading to the Green Car.
- Large luggage: Reserve a last-row seat to access the designated luggage storage space.
- Quiet travel: An aisle seat in the middle of the car tends to have less foot traffic and noise.
- Groups: Book adjacent rows in ordinary class or seat pairs together in the Green Car.
- Flexibility: Unreserved cars allow last-minute boarding, but expect crowding during peak times.
- Middle seat (B): Avoid this seat on longer trips, as it offers the least space and comfort.
If you’re planning routes between major cities like Tokyo and Osaka, these choices can make a noticeable difference in comfort.
