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 1 GB / 7 days at $4.50 up to 10 GB / 30 days at $18.00. 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.

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.

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