How it works

Buy. Scan. Land online.

Three steps, two of them at home. Here is exactly what happens from checkout to bars on your phone.

Scenic railway crossing an autumn river gorge in Japan — Buy before the flight, use from the gate

Senbon torii gates at Fushimi Inari shrine, Kyoto — Maps and trains, covered

Kiyomizu-dera pagoda lit at night in autumn — Evening plans still online

Step 1: buy online

Pick a plan in the store, leave an email, pay by card on Stripe's own page; Apple Pay and Google Pay work there too. The receipt comes from Fizen LLC, the company behind this store.

Step 2: scan the QR at home

The QR code lands in your inbox within minutes. Scan it on home Wi-Fi and the eSIM installs in about two minutes. Do not delete it after; a QR installs once. Exact taps for iPhone and Android are in the install guide below.

Step 3: land and switch on

At the gate: travel line ON, set as Mobile Data, Data Roaming ON for that line. Bars on KDDI 4G or 5G show within about a minute. Your days start per the rule printed at checkout: at install, or at first connection in Japan.

If anything fails

Run the five-step rescue card; it solves most cases in two minutes. Still dark: message the chat or [email protected] and a human answers. A faulty eSIM is replaced one for one; an unused plan can be refunded under its package terms.

Straight answers

How fast do I get the eSIM after paying?

The QR arrives by email within minutes of payment.

Do I need the app or an account?

No. Email, card, QR. Nothing to install except the eSIM itself.

When do my days start counting?

Not at purchase. Checkout states each plan's rule: at install, or at first connection in Japan.
