Japan eSIM at Narita and Haneda: Get Connected the Moment You Land
If you've installed a PlanJapan eSIM before departure, you'll be connected to the Japanese network (NTT Docomo or SoftBank) the moment your plane lands at Narita or Haneda â no queues, no counter, no physical SIM card. Just install the eSIM profile on your phone 2â3 days before flying, and the connection activates automatically on arrival. It's the fastest, most affordable way to stay connected from the second you step off the plane.
Narita and Haneda: Two Airports, One Priority â Getting Connected
Tokyo's two international airports handle the vast majority of foreign visitors arriving in Japan:
- Narita (NRT) â 60 km from Tokyo, in Chiba Prefecture. Three terminals. The main hub for long-haul flights from Europe and the Americas.
- Haneda (HND) â 14 km from central Tokyo, on Tokyo Bay. Four terminals. Closer to the city center, it has been handling a growing number of international flights since 2021.
In both cases, the challenge is the same: when you land, your phone has been in airplane mode for hours, and you need internet immediately â to find your train, call someone, or check your accommodation details.
Airport SIM Counter vs. Pre-Purchased eSIM
Airport SIM Counters: Convenient in Theory, Frustrating in Practice
At Narita and Haneda, several carriers and resellers offer physical SIMs and some eSIMs:
| Terminal | Carrier / Shop | Hours |
|---|---|---|
| Narita T1, T2 | IIJmio, SoftBank, BIC Camera | 9:00â21:00 |
| Narita T2 | SIM Vending Machines | 24/7 |
| Haneda T2 | SoftBank Counter | 8:00â20:00 |
| Haneda T3 (International) | BIC Camera, NINJA WiFi | 7:00â22:30 |
The problems:
- Limited hours â if your flight lands at 6 AM or 11 PM, the counter is closed
- Peak-hour queues of 15 to 45 minutes during busy travel seasons
- Higher prices than online â a 20 GB SIM can cost 3,500 to 8,000 „ at the airport
- Many counters still only offer physical SIMs, not eSIM
- Manual APN configuration sometimes required
Pre-Purchased eSIM: The Smart Choice
By installing your PlanJapan eSIM 2 to 3 days before departure, you avoid all of the above:
- You receive a QR code by email
- Scan the QR code and install the eSIM profile (2 minutes)
- On the plane, your eSIM waits in standby
- The moment you land at Narita or Haneda, it connects automatically to NTT Docomo
Result: you're online before you even reach the baggage carousel.
How to Get Connected the Moment You Land
Step 1 â Install the eSIM Before You Leave (Ideally 2â3 Days Out)
Buy and install your PlanJapan eSIM 2 to 3 days before your flight to avoid any last-minute issues. Installation takes about 2 minutes:
- iPhone: Settings > Cellular > Add eSIM > Scan QR Code
- Android (Samsung, Pixel): Settings > Connections > SIM Manager > Add Mobile Plan
Once installed, you can leave the PlanJapan line disabled until you land â it won't consume any data until you're in Japan.
Step 2 â Check Your Settings Before the Flight
On your phone, make sure:
- PlanJapan is set as your default data line
- "Data Roaming" is turned on (required for the eSIM to work abroad)
- Roaming is allowed in the eSIM line settings
Step 3 â On Landing: Turn Off Airplane Mode
Once the captain clears electronic device use:
- Turn off airplane mode
- Your phone searches for a network automatically
- NTT Docomo or SoftBank appears in the status bar
- You're online â Maps, WhatsApp, email all work instantly
Average connection time: 20 to 60 seconds after disabling airplane mode.
Mobile Coverage Inside Narita and Haneda
NTT Docomo provides full 4G/5G coverage throughout both airports, including:
- Arrivals and departures halls
- Transit corridors
- Customs and passport control areas
- Integrated rail links (Narita Express, Keikyu Line from Haneda)
Indoor coverage is excellent at both airports. You won't hit any dead zones while waiting for your luggage or heading to the train.
Narita note: The three terminals are connected by a free inter-terminal bus â mobile coverage stays active on the bus too.
PlanJapan eSIM: Which Plan Should You Choose?
Depending on your trip length and usage:
| Plan | Ideal For | Profile |
|---|---|---|
| 10 GB | Under 1 week | Maps, messaging, light use |
| 20 GB | 10â12 days | Social media, navigation, no heavy streaming |
| 50 GB | 2 weeks | Full use: Maps, Instagram, video, hotspot |
| Unlimited | Any length | Zero restrictions â ideal for heavy users |
For a standard 2-week trip to Japan, the 50 GB plan is our top recommendation â more than enough for Maps, social media, video calls, and occasional hotspot sharing.
If you don't want to track your data at all, or you're sharing your connection with other devices, go with the unlimited plan â total peace of mind from the moment you land.
Frequently Asked Questions
Can I get connected the moment my plane lands at Narita or Haneda?
Yes, if you've installed a PlanJapan eSIM before departure. As soon as you turn off airplane mode, your phone automatically connects to the NTT Docomo or SoftBank network. You'll be online before you even reach passport control.
Can I buy and install an eSIM at the airport if I didn't do it beforehand?
Yes, as long as you can access the airport's free Wi-Fi. Connect to Wi-Fi, purchase your PlanJapan eSIM, scan the QR code â your line is active within minutes. Less convenient, but perfectly doable.
Does the eSIM work on the Narita Express (NEX) or the Keikyu to Haneda?
Yes. NTT Docomo covers both airport rail links to central Tokyo, including the undersea tunnels on the Keikyu line. You may experience very brief drops (under 5 seconds) in deep tunnels, but the connection resumes immediately.
Do I need a physical SIM at the airport, or is an eSIM enough?
An eSIM is more than enough. If your phone is eSIM-compatible (iPhone XS or newer, Samsung Galaxy S21 or newer, Pixel 6 or newer), there's no reason to buy a physical SIM at the airport â the eSIM is faster, cheaper, and easier.
How do I check if my phone is eSIM compatible before I travel?
On iPhone: Settings > General > About > look for "EID". If the field is there, your iPhone supports eSIM. On Samsung: Settings > General Management > Phone Information > look for "EID". On Pixel: Settings > About Phone > IMEI Information > look for "EID".
Does the eSIM work across all three terminals at Narita?
Yes. Narita has three terminals (T1, T2, T3). NTT Docomo covers all three, including the inter-terminal buses and transfer zones. Coverage is the same regardless of which terminal you arrive at.
