Rakuten Mobile for Foreigners in Japan: The 15-Minute Setup Guide (2026)

Quick answer

Hi, I'm Miya, and I help newcomers get connected in Japan — mobile is where I always start. If you live here and want the simplest, cheapest unlimited SIM, Rakuten Mobile is the one I point people to first: one plan, no data caps, no throttling, and you can activate it by eSIM the day you arrive.

The plan and price

Let me break down what you'll actually pay. It's one tiered plan (the SAIKYO plan): ¥1,078/mo for 0–3GB, ¥2,178 for 3–20GB, and ¥3,278 for unlimited — all tax included. I like recommending it because it's Japan's only truly unlimited plan at a fixed price, so your bill never surprises you.

Can foreigners sign up? (yes — here's what you need)

This is the question I get most, and the answer is yes. You verify your identity by photographing your residence card (在留カード) — no store visit needed. Most work and spouse visas are eligible; I'd just check your card has at least ~3 months of validity left. You'll also need a Japanese card or bank account to pay.

Coverage

People always ask me whether it'll reach their neighborhood. Rakuten Mobile's own network covers Japan's population widely and keeps expanding — I'd check the official area map for your exact address before you commit.

Free calls with the Rakuten Link app

One thing I always set up with people: the Rakuten Link app, which makes domestic calls free. Placing one 10-second call through it is also how the referral bonus gets completed, so I never let anyone skip that step.

The Rakuten ecosystem: points and everyday perks

Here's where it becomes bigger than a phone plan. As a Rakuten Mobile member you earn extra points when you shop at Rakuten Ichiba, and your plan includes Rakuten Drive with 50GB of free cloud storage.

There's no extra fee for Pacific League baseball either, plus music and magazine perks — the small everyday extras I think of as smarter, more connected living, not just raw connectivity.

Overseas roaming: up to 2GB free

Traveling outside Japan? I love that your plan includes up to 2GB of international roaming at no extra charge (it counts toward your plan data), so your number keeps working abroad without a separate SIM.

Age-smart savings

If there's a child, a young person, or a senior in your household, ask me about the age discounts: one for children up to 12, one for young users up to 22, and a senior program from 65 that adds a monthly point rebate and unlimited 15-minute calls. Each needs registration — check the official page for current amounts.

Set up by eSIM in ~15 minutes

When you're ready, here's the fast path I walk people through: apply online, upload your residence card, and if your phone supports eSIM you can be connected the same day. A physical SIM by mail takes 2–5 days.

FAQ

Do you need Japanese? The core steps run from the app; I'll cover the parts that are Japanese-only.

Is there a contract lock-in? No — the plan itself has no fixed-term lock-in, which is why I'm comfortable recommending it.
