Best SIM Without a Japanese Credit Card or Bank Account
Sponsored / Contains affiliate links
If you only read this part
The big cheap carriers (LINEMO, povo, ahamo, Rakuten) almost all need a Japanese credit card or bank account. If you don't have one yet, your realistic options are Mobal (accepts foreign cards, PayPal, and convenience-store payment, and gives you a real Japanese phone number) and Sakura Mobile (foreign cards, full English support).
If you just need data and not a phone number, a travel eSIM (Airalo, Ubigi) bought with your foreign card works in minutes. Use it as a bridge until your Japanese bank setup is done, then switch to a cheaper domestic plan.
Section 01
Why this is the hardest part of getting a SIM.
Of all the requirements for a Japanese SIM, the payment method trips up more foreigners than anything else. You can have a valid residence card, a working unlocked phone, and a Japanese address — and still get rejected at the final step because your credit card was issued overseas.
This catches people off guard because it feels backwards. In most countries, a foreign card with a good limit is welcome anywhere. In Japan, domestic carriers route billing through systems that often can't process overseas cards, and several treat a Japanese payment method as part of their identity check. It isn't about whether you'll pay — the pipes simply aren't built for foreign cards.
The result is a chicken-and-egg problem familiar to anyone who has moved to Japan: you need a phone number to open a bank account, and you need a bank account (or Japanese card) to get a phone plan. The providers below exist specifically to break that loop.
Section 02
What each carrier accepts.

Section 03
The card-free paths, ranked.
1. Mobal — the most flexible
Mobal is the closest thing to a universal answer. It accepts foreign credit cards, PayPal, and Alipay, and has offered convenience-store cash payment — meaning you can get a real Japanese phone number (070/080/090) without any Japanese card or bank account at all. The Voice Lite plan starts at ¥990/month for a phone number with light data, and there's a Voice+Data option for up to 30GB. It runs on SoftBank's network, ships worldwide for free, and offers full English support.
2. Sakura Mobile — full English, card-based
Sakura Mobile accepts foreign credit cards and is built end-to-end for non-Japanese speakers — English sign-up, English support, docomo network. It doesn't do convenience-store cash, so you still need a card of some kind, but a foreign card works. Good for people who have an overseas card but no Japanese banking yet.
3. Travel eSIM — fastest, data only
If you don't need a phone number yet, a travel eSIM is the quickest card-free-ish option: buy it with your foreign card or Apple Pay, and you're online in minutes. Airalo and Ubigi both work this way. The catch is no Japanese phone number, so you can't receive SMS verification codes from Japanese services. Best used as a bridge for your first few weeks.

Section 04
The bridge strategy.
Most people in this situation are better served by a two-step plan than by forcing one perfect choice.
Week 1–4: Get online and reachable immediately. If you only need data, a travel eSIM is enough. If you need a Japanese phone number — to open a bank account, sign a lease, or register for services — start with Mobal, since it needs no Japanese card.
After your bank setup: Once you have a Japanese bank account and ideally a Japanese credit card, the cheaper domestic carriers open up. Switching from a foreigner-focused voice plan to LINEMO or povo can roughly halve your monthly bill. Use an MNP transfer to keep the number you've already given people.
This avoids the most common mistake: signing a more expensive plan out of urgency and then never switching, quietly overpaying for years.
Section 05
What to have ready before you apply.
- Your residence card, if you have oneFor a voice plan with a Japanese number, ID verification is generally required by Japanese telecom regulations, even with the foreigner-focused providers.
- A payment method that the provider actually acceptsConfirm before ordering: a foreign credit card for Sakura Mobile; a foreign card, PayPal, or konbini cash for Mobal; Apple Pay or a foreign card for travel eSIMs.
- An unlocked phoneCheck it's carrier-unlocked and supports Japan's LTE bands (1, 3, 19, 28). Most iPhones from iPhone 7 and most flagship Androids from the last few years are fine.
- A delivery address or pickup planMobal and Sakura Mobile can ship internationally or hold a SIM for airport pickup. eSIMs are delivered instantly by email/app.

FAQ
Frequently asked questions
Can I really get a SIM in Japan without a Japanese credit card?
Yes, but your options narrow. The big domestic carriers (LINEMO, povo, ahamo, Rakuten) almost always require a Japanese-issued credit card or bank account. Foreigner-focused providers like Mobal and Sakura Mobile accept foreign credit cards, PayPal, and in some cases convenience-store payment, which is why they are the standard answer for newly arrived residents who don't have a Japanese card yet.
Why do Japanese carriers reject foreign credit cards?
Japanese carriers run billing through domestic payment systems and often can't process foreign-issued cards reliably. Some also treat a Japanese payment method as part of their identity verification. It isn't about your creditworthiness — the system simply isn't built to accept overseas cards.
Can I pay for a SIM at a convenience store?
Yes, with some providers. Mobal has offered convenience-store payment options that let you pay the bill in cash at any konbini, which means you need neither a Japanese bank account nor a credit card. This is one of the few genuinely card-free paths to a Japanese phone number.
Do I need a residence card if I don't have a credit card?
These are two separate requirements. Mobal and Sakura Mobile can issue a SIM with passport-only or pre-arrival sign-up for some plans, but for a voice plan with a real Japanese phone number, Japanese telecom regulations generally require ID verification. Check each provider's specific requirements before ordering.
What's the fastest card-free option for someone who just landed?
A travel eSIM (Airalo, Ubigi) bought with your foreign card or Apple Pay gets you online within minutes — no Japanese payment method needed. Use it for your first few weeks, then move to a domestic plan once your Japanese bank account and card are set up. For a phone number from day one, Mobal is the usual choice.
Once I get a Japanese bank account, should I switch?
Usually yes. Foreigner-focused carriers cost more per month than domestic plans. Once you have a Japanese credit card or bank account, switching to LINEMO (¥990–¥2,970) or povo can roughly halve your monthly bill compared to a foreigner-focused voice plan. Keep your number using an MNP transfer.
