Picture this: you’re gliding past Mt. Fuji, the snow-capped peak perfectly framed in the window — and your phone dies before you can take the photo.
Or worse: you arrive at your next stop and realize your Google Maps, translation app, and e-tickets are all unreachable because your battery hit zero mid-journey.
The good news? Most Shinkansen trains do have power outlets — but availability depends on your seat type, seat number, and the specific train series. This guide breaks it all down so you can book the right seat and travel with peace of mind.
⚡ Quick Answer
Yes — power outlets are available on the Shinkansen, but not at every seat. Green Car (first class) seats always have outlets. In Ordinary Cars, outlets are typically found at window seats and the front/back rows of each car, depending on the train series. The newest N700S trains have outlets at every seat.

Can You Charge Your Devices on the Shinkansen?
Yes — but there’s a catch. Outlet availability varies by train series and seat type. Here’s the breakdown:
By Seat Type
| Seat Type | Power Outlet | Notes |
|---|---|---|
| Green Car (First Class) | ✅ Every seat | All Green Cars on major Shinkansen lines include outlets. The most reliable option. |
| Ordinary Car (Standard) | ⚠️ Selected seats only | Typically window seats (A & E) and front/back rows of each car. Varies by train model. |
Not sure which class to choose? Here’s a quick summary:
- Green Car — Wider seats, quieter environment, guaranteed outlet, higher price
- Ordinary Car — Standard seating, more affordable, outlet availability varies
By Train Series (Tokaido & Sanyo Shinkansen: Tokyo ↔ Osaka ↔ Hakata)
| Train Series | Ordinary Car Outlets | Green Car Outlets |
|---|---|---|
| N700S (newest) | ✅ Every seat | ✅ Every seat |
| N700A / N700 | ⚠️ Window seats (A & E) + front & back rows per car | ✅ Every seat |
Pro tip: If you’re traveling on the Tokaido Shinkansen and want an outlet guaranteed in Ordinary Class, try to book an N700S train. You can check the train series when booking.
How to Book a Seat with a Power Outlet
Knowing where outlets are is one thing — securing that seat is another. Here are three reliable ways to do it:
1. When Booking Online
When selecting your seat, look for a “window seat” option, or specifically ask for seats in the first or last row of a car. Online booking platforms like Klook make it easy to filter by seat type.
2. At a Ticket Machine
Select the “window seat” option when prompted. On newer train models (especially N700S), almost all seats have outlets anyway — but window seats are the safest bet on older trains.
3. At the Ticket Counter (Midori no Madoguchi)
This is the easiest option if you’re unsure. Walk up to the counter and say:
“Can I have a seat with a power outlet, please?”
Staff are accustomed to this request and will find you the right seat.
Special Note for JR Pass Holders
If you’re using a Japan Rail Pass (JR Pass), you’ll need to exchange your voucher for the physical pass at a JR ticket office before you can make seat reservations. Once exchanged, simply ask the counter staff for a seat with a power outlet — they’ll handle the rest.
💡 Traveling Multiple Routes? A regional JR Pass could save you significantly compared to buying individual tickets — especially if you’re covering multiple Shinkansen lines.

3 Things to Pack for Worry-Free Charging
1. Your Own Charging Cable
The Shinkansen provides the outlet — the cable is your responsibility. Don’t forget to pack yours before you leave your hotel.
2. A Portable Power Bank (Highly Recommended)
Even with outlets available, there are scenarios where they might be occupied or temporarily non-functional. A reliable power bank is your ultimate backup.
🔋 Recommended: A compact, high-capacity power bank means you’ll never worry about outlets again — whether you’re on the Shinkansen, a local train, or exploring a city.
3. Voltage Adapter (If Needed)
Japan runs on 100V. Most modern smartphones, laptops, and USB chargers are universal (100–240V) and will work just fine without an adapter. Check your charger’s label to confirm.
