Choosing a mobile plan in Japan is not only about the cheapest monthly fee. Foreign residents should compare documents, payment methods, coverage, data allowance, contract rules, and how easy the setup is.
Start with the mobile plan comparison page if you need a shortlist.
Start with your constraints
If you do not have a Japanese credit card yet, filter for plans that accept your current payment method. If you need stable service immediately after arrival, a major carrier or online sub-brand may be safer than the lowest-cost option.
What to compare
- Monthly price and data amount
- Residence card requirements
- Credit card or bank account requirements
- eSIM support
- Online signup availability
- Cancellation terms
- Customer support language
Practical choice pattern
Major carriers are useful when you want store support and stable coverage. Budget SIMs can be good if you are comfortable with online setup and APN settings. eSIMs are convenient for arrival week, but check long-term identity verification and payment rules.
Common pitfall
Do not compare only the promotional headline price. Real costs can change based on calls, data tiers, discounts, and required payment methods. Prepare your ID, address, and payment method before applying.
Next step
Compare povo, LINEMO, Rakuten Mobile, ahamo, and UQ mobile, then read povo, LINEMO, Rakuten Mobile, and ahamo for the broader decision frame. If you are still in arrival week, use First Week in Japan to decide what to set up first.
