Overview

What is Airalo?

Airalo is the world's largest eSIM marketplace, founded in 2019 and now trusted by over 10 million travellers across 190+ countries. Rather than operating its own network, Airalo partners with local carriers — in Japan's case, Docomo and SoftBank — and sells data-only eSIM plans through its app and website.

For Japan, Airalo sells plans under the “Moshi Moshi” brand. Plans range from $4.00 / 1 GB / 3 days up to 20 GB and unlimited options (unlimited from $26.50 (Unlimited / 7 days)); prices below were checked on 20 Oct 2026. All plans are data-only — there are no voice calls or SMS included.

The key appeal is simplicity: buy before you fly, scan a QR code, and you have working 4G the moment you land at Narita or Haneda. No queuing at airport SIM vending machines.

Setup guide

How to Set Up Airalo Japan eSIM

Download the Airalo app

Available free on iOS and Android. Create an account — it takes under a minute.

Purchase your Japan plan

Search for Japan, pick your plan (we recommend Moshi Moshi M for most visitors), and checkout. You'll receive a QR code instantly.

Scan QR code in Settings

Go to Settings → Cellular (or Mobile Data) → Add eSIM → Scan QR Code. Takes under 2 minutes and can be done at home before you fly.

Activate on arrival in Japan

Switch to your Airalo Japan eSIM profile when your plane lands. You'll have a live 4G signal before you reach baggage claim.

Bottom line

Verdict

Airalo Japan is an excellent choice for most travellers, especially those visiting for a week to a month. The combination of reliable Docomo/SoftBank coverage, competitive pricing, and near-instant setup makes it hard to beat as a first-time eSIM experience.

The only real downsides are the data-only limitation (no calls or SMS) and occasionally slow customer support responses — neither of which will affect most tourists who rely on WhatsApp or LINE for communication.

For budget travellers or anyone who wants the simplest possible connectivity solution, Airalo Japan is our top pick. For unlimited data or longer stays with voice requirements, consider Holafly or Sakura Mobile instead.

Does Airalo work in Japan?

Does Airalo Work in Japan? Coverage, Speed & Fixes

Short answer: yes, nationwide. Here's what we found on coverage and speed, plus the quickest fixes for the handful of issues travellers run into.

1. Does Airalo actually work in Japan?

Yes — Airalo Japan eSIM works nationwide via Docomo and SoftBank networks, which both publish coverage across the cities and the main intercity rail corridors, including the Tohoku Shinkansen. The gaps are deep mountain trails and small remote islands, which have limited coverage regardless of carrier.

2. Which network does Airalo use in Japan?

Airalo Japan plans run on Docomo and SoftBank — Japan's two largest networks by coverage. Docomo, in particular, has the best rural and mountainous coverage in the country. You won't need to manually select a network; your phone picks the strongest signal automatically.

3. How fast is Airalo in Japan?

Airalo rides Docomo and SoftBank 4G LTE, which typically runs at roughly 30–150 Mbps down in Tokyo, Osaka and Kyoto — more than enough for Google Maps, streaming, and video calls. Rural figures are lower, typically 10–40 Mbps, which is still perfectly usable.

4. Can I use Airalo on the shinkansen?

Yes. Shinkansen trains are covered by Docomo and SoftBank along all major lines, including Tokaido (Tokyo–Osaka), San'yo (Osaka–Hiroshima–Hakata), and Tohoku. Expect brief signal gaps inside tunnels, which can last 30–60 seconds.

5. Is Airalo better than buying a SIM at the airport?

For most travellers, yes. Airport SIM vending machines (IIJmio, JTRIP, etc.) require queuing on arrival and often cost more per GB. Airalo can be purchased and installed from home — you'll have live data the moment you land, without any queuing or paperwork.

Problem	Fix
eSIM not connecting after arrival	Toggle airplane mode on and off. If still no signal, go to Settings → Cellular / Mobile Data and manually select your Airalo profile.
QR code won't scan	Make sure you haven't already scanned it — eSIM QR codes are single-use. Open the Airalo app and tap 'My eSIMs' to find an alternative installation option (manual details).
Data working but very slow	Check your APN settings. Go to Settings → Cellular → Cellular Data Options → APN and confirm the APN matches the details in the Airalo app. Alternatively, restart your phone.
eSIM shows as active but no internet	Ensure 'Data Roaming' is turned on for your Airalo profile. On iPhone: Settings → Cellular → Airalo plan → enable Data Roaming. On Android: Settings → Network → Mobile Data → Roaming.

FAQ

Common Questions

1. Is Airalo legit?

Yes. Airalo is a legitimate, well-established company founded in 2019 and trusted by over 10 million travellers worldwide. They operate as a licensed eSIM marketplace and partner with major carriers globally, including Docomo and SoftBank in Japan.

2. Does Airalo work in rural Japan?

Airalo Japan runs on Docomo and SoftBank networks — two of Japan's three main carriers. Docomo has the broadest rural coverage in Japan. In practice, you'll have signal on popular tourist routes including mountainous areas like Nikko and Hakone. Very remote areas (deep mountains, some islands) may have limited coverage regardless of carrier.

3. Can I top up my Airalo eSIM in Japan?

Yes. You can purchase an additional plan from the Airalo app while in Japan and it will top up your existing eSIM profile. No need to scan a new QR code.

4. Is Airalo cheaper than roaming?

Almost always, yes. Most international roaming plans charge $10–15 per day. Airalo's Japan plans start at $4.00 / 1 GB / 3 days — less than a single day of roaming. For a two-week trip, a 5 GB plan at $10.00 (5 GB / 7 days) is dramatically cheaper than roaming.

5. Can I use Airalo on iPhone?

Yes. iPhone XS (2018) and later support eSIM. Go to Settings → Cellular → Add eSIM and scan the Airalo QR code. Note: iPhones purchased from some carriers (especially older unlocked units from certain regions) may have eSIM locked. Check with your carrier if unsure.
