“I have no idea which phone plan to choose in Japan…”
If that sounds like you, here’s the short answer: mobile phone retailers who specialize in serving foreign customers say the same thing every time — “Rakuten Mobile is the only choice.” The reason is simple.
Why foreign workers choose Rakuten Mobile
① Watch your favorite content from home — no limits
② Stay connected with family back home — worry-free
Both require truly unlimited data. In Japan, only Rakuten Mobile offers that.
You will need to log in with a Rakuten ID at the application page. If you don’t have one, you can create a free Rakuten account in about 3 minutes.
🌏 Reason #1 — Japanese content is boring. Stream what you love from home.
Living in Japan means TV, news, and the internet are all in Japanese. Many foreign workers find it exhausting or just not interesting.
The solution almost every foreign worker relies on: using their smartphone to enjoy content from home.
🎬
YouTube
Watch videos in your language all day
📺
Netflix / TikTok
Dramas and trending content from your country
🎮
Online Gaming
Connect to overseas servers with no data cap
🎵
Music Streaming
Latest tracks from your favorite artists at home
Using these every day can easily push your data usage past 20GB–50GB per month.
Most budget SIM plans and even some major carrier plans will throttle your speed long before you get there — making your phone practically unusable.
Key point: Truly unlimited data for ¥3,278/month (tax included) is available from Rakuten Mobile only in Japan. That’s more than ¥4,000 cheaper per month than equivalent plans from major carriers.
📞 Reason #2 — Call and video chat with family back home. No worries.
For foreign workers in Japan, staying in touch with family and friends back home is an everyday necessity.
💬
LINE Video Calls
30-minute to 1-hour video calls — no data anxiety
📱
WhatsApp / WeChat
Group calls, photos, and video — send as much as you want
📞
Free Calls via Rakuten Link
Domestic calls are free when using the Rakuten Link app
✅ From a mobile phone retailer:
“We’ve helped customers from Vietnam, Nepal, the Philippines, Indonesia, and many other countries find the right phone plan. For every foreign customer, our recommendation is always the same: Rakuten Mobile. The combination of unlimited data and low price is simply unmatched.”
