Rakuten Mobile English Guide 2026: Best SIM for Expats in Japan - 楽天モバイル従業員紹介キャンペーン【現役社員ブログ】
Rakuten Mobile for Foreigners in Japan
Stop Overpaying. Start Saving. The 2026 Guide.
Up to Unlimited Data from ¥3,278/mo | English-Friendly | No Long-Term Contract | Bonus Points via Referral
Are You Paying Too Much for Your Phone Plan?
Moving to Japan is exciting, but navigating mobile phone contracts can be stressful. Some carriers require
complicated paperwork, and it’s easy to end up with a plan that feels expensive for what you get.
If you want to keep your current number, choose MNP (switching from another carrier). It often qualifies for a bigger points bonus.
For international students, expats, and technical interns, monthly costs add up quickly. Language barriers can
make it even harder to compare options confidently.
Why Rakuten Mobile Works Well for Expats
Rakuten Mobile offers a simple plan structure known as the Rakuten SAIKYO Plan.
It’s designed to reduce typical pain points for foreign residents: cost, language, and contract flexibility.
English-Friendly Experience
Key steps of the website and app are available in English. Multi-language support is also offered for select channels.
Clear, Simple Pricing
The price automatically adjusts based on how much data you use—easy to understand, easy to manage.
Overseas Data Included
Overseas roaming data is included for eligible countries/regions each month (commonly listed as 2GB). Great for short trips.
Calls via Rakuten Link
Using the Rakuten Link app, domestic calls may be available at no extra charge (conditions apply).
Simple Pricing Structure
Rakuten Mobile uses a tiered price that changes automatically based on your monthly data usage.
| Data Usage | Monthly Cost (Tax Incl.) | Best For |
|---|---|---|
| 0 GB – 3 GB | ¥1,078 | Light users, WiFi reliance |
| 3 GB – 20 GB | ¥2,178 | Commuters, Social Media |
| 20 GB – Unlimited | ¥3,278 | Heavy users, Video streaming |

Coverage and Network Quality
Coverage continues to expand across Japan, combining Rakuten’s own network with partner areas.
For best results, check coverage maps for your city and the places you commute to most often.
Network performance can vary by building structure and location (for example, underground spaces).
If signal is important for your work or school, a quick coverage check before applying is recommended.
