Rakuten Mobile Frequently Asked Questions (Foreigners & Students)

Question 1

Do I need to be a Japanese resident to get a mobile plan?

Accepted Answer

Most carriers require you to be a resident of Japan with a valid residence card (zairyu card) and Japanese address. However, Rakuten Mobile is comparatively flexible for medium/long‑term visa holders. You'll typically need a Japanese bank account or credit card for payment. Unsure which plan tier fits your expected data usage? Review the options on /plans for data-breakpoints and pricing, then verify local service quality with /coverage before applying.

Question 2

Is English customer support available?

Accepted Answer

Rakuten Mobile offers English customer support through chat and phone (availability hours can vary). Other major carriers (DoCoMo, SoftBank, au) provide limited English support via specialized channels. If English support is a priority, confirm Rakuten's service quality for where you live and commute using /coverage, then choose a plan that matches your data usage on /plans.

Question 3

What documents do I need to sign up for a mobile plan?

Accepted Answer

You'll usually need: (1) Residence card (zairyu) + passport, (2) Proof of Japanese address, (3) Japanese bank account or credit card, (4) Sometimes a personal seal (hanko). Rakuten Mobile online applications rely on eKYC so make sure the address matches exactly. After gathering documents, review the options on /plans to select a data tier, then check /coverage to ensure strong reception in your area before submitting your application.

Question 4

Can I cancel my contract if I leave Japan?

Accepted Answer

Yes. Rakuten Mobile has no fixed‑term contract or cancellation fee. Legacy carrier 2‑year style plans may still charge a penalty. If you might leave Japan sooner than a year, the flexibility of Rakuten's scalable data tiers (which you can see on /plans) is a major benefit. Before committing, we recommend verifying that your most frequented prefectures have adequate service on /coverage.

Question 5

What's the difference between Rakuten's own network and partner network?

Accepted Answer

Rakuten's own network (urban cores) provides higher sustained speeds & effectively unlimited data within fair use. The domestic partner (au) roaming network covers rural gaps and is capped at 5GB/month before 1Mbps throttling. Use /coverage to see which prefectures and cities fall under each network type. If you primarily reside in a partner area, evaluate whether the data tiers on /plans still meet your monthly usage after potential throttling.

Question 6

Can I use international roaming with Japanese mobile plans?

Accepted Answer

Yes. Most carriers offer roaming add‑ons; Rakuten Mobile includes competitive roaming and free international calls to 60+ countries via Rakuten Link. If you travel often, factor projected abroad usage into your domestic data selection on /plans and ensure strong home base connectivity via /coverage so throttling at home does not compound travel needs.

Question 7

What payment methods are accepted?

Accepted Answer

Most carriers accept Japanese credit cards and bank transfers. Some international cards work but success varies. Rakuten Mobile is comparatively flexible. When budgeting, map your expected monthly data tier cost from /plans and confirm you will actually benefit from higher tiers by checking your daily locations on /coverage first.

Question 8

How long does it take to get service activated?

Accepted Answer

eSIM: often active within hours after approval. Physical SIM: 1–3 business days shipping. Identity (eKYC) review may add 1–2 days. To avoid delays, verify your service quality on /coverage so you can select the optimal tier from /plans immediately and avoid a post‑activation plan change.

Question 9

Are there student discounts available?

Accepted Answer

Some carriers run student promos but many target domestic students only. Rakuten Mobile's tiered pricing, which you can review on /plans, already starts low (from ¥1,078) so dedicated student discounts are less critical. We recommend confirming campus and dorm reception with /coverage before locking in any data assumptions.

Question 10

Can I keep my phone number if I switch carriers?

Accepted Answer

Yes. Japan supports Mobile Number Portability (MNP). Obtain an MNP reservation number from your current carrier; activation after submission typically finalizes within 1–2 business days. Before porting, check /coverage to ensure Rakuten's network is strong in your daily zones and align your new plan from /plans with your historic monthly usage.

Question 11

What happens if I don't pay my bill on time?

Accepted Answer

Late payment risk timeline: reminder → temporary restriction (~10–15 days) → suspension → potential termination & collections after 2–3 months. This can impact future applications. If budgeting is tight, choose a conservative data tier from /plans initially and scale up only if real usage warrants it. Our /coverage map can help confirm you will fully utilize higher‑speed areas.

Question 12

Do I need a Japanese guarantor for mobile service?

Accepted Answer

Most carriers no longer require guarantors; some may request deposits for short‑term visa holders. Rakuten Mobile typically doesn't require a guarantor. First, validate the network quality in your prefecture with /coverage, then select the smallest feasible tier on /plans and upgrade later if your data usage consistently approaches the upper threshold.
