You have just landed in Japan, you need a phone plan, and every sign-up form seems to ask for a Japanese credit card you do not have yet. It feels like a loop: you need a number to open a bank account, and you need a bank account or card to get a number. The good news is that the loop can be broken, and this guide walks you through how.
Why the credit card question feels like a wall
Many Japanese mobile contracts are built around a local credit card or a local bank account for monthly payments. For people who grew up in Japan this is normal. For newcomers it is a problem, because a Japanese credit card usually comes after you have a bank account, a stable address and some history in the country.
That is why so many people arriving to study or work end up stuck in their first weeks. They may have a perfectly good card from home, plenty of savings and a valid visa, yet the form simply has no option that fits them. It is not about whether you can pay. It is about whether the system recognises how you pay.
The practical answer is to look for a provider that does not make a Japanese credit card a requirement in the first place. With shibaSIM, a Japanese credit card is not required for resident plans. Instead of guessing, you talk to a person first and agree on a payment method that actually works for you.
How payment works when you do not have a Japanese card
Before you pay anything for a resident plan, staff confirm a payment method that works for you in chat. This step exists because newcomers arrive with very different situations: some have only a card from home, some already have a Japanese bank account, some are waiting for one. Sorting this out at the start avoids the frustration of filling in a long form only to be rejected at the last screen.
Support is given by real people in English, from 8:00 to 22:00 Japan time (JST). You can reach the team on WhatsApp or by email at [email protected]. Explain where you are in your move, which plan you are interested in and what payment options you have, and staff will tell you what is possible.
Tip: Never type or send your card number in a chat message or an email. Card details belong only in the secure payment form. A genuine support team will never ask you to share them in a conversation.
Your first days: a travel eSIM as a bridge
A very common situation is arriving in Japan before your residence card and address are fully sorted. You might be in temporary housing, waiting for paperwork, or simply too jet-lagged to deal with contracts. During this period you still need maps, messaging apps and a way to contact your school, employer or landlord.
A travel eSIM fills that gap. It needs no documents, it is valid for 5 to 30 days, and you pay online by card, including a card issued in your home country. Prices are shown in US dollars on the plans page, and payment is processed by Stripe. After payment you receive a QR code, which normally arrives within 30 minutes during support hours, and you install it on your phone.
Because a travel eSIM runs alongside your home SIM, you can keep your usual number active for bank messages from home while using Japanese data. eSIM works on iPhone XR/XS and later and on most higher-end Android phones from 2019. Once your residence card and address are ready, you can move to a resident plan without having been offline in between. As a rough estimate, basic use needs about 1GB per day, which helps you pick a sensible data size for those first weeks.
Choosing the right resident plan for your situation
Resident plans are easier to choose when you start from what you actually need rather than from data sizes. There are three main options, each matched to a typical situation.
The Student plan gives you 5GB of data only. It has no SMS and no phone number, so it suits someone who mainly uses internet apps for messages and calls and has Wi-Fi at home or on campus. The Work plan gives you 20GB and includes SMS, but no callable number. It fits people who need more data and want to receive text messages, for example some verification codes.
The Japanese phone number plan gives you 20GB, SMS and a real Japanese mobile number starting with 090, 080 or 070 that can make and receive calls. This is the plan to consider if you are about to deal with banks, landlords or employers. Keep in mind that SMS is only available when a plan explicitly includes it, and delivery of verification codes depends on the app and the sender, so it is not guaranteed for every service.
Why a real Japanese number matters more than you think
Many newcomers start with a data-only plan because it seems enough. Messaging apps work, maps work, and calls over the internet work. The surprise usually comes later, when an official form asks for a phone number and an app number is not accepted.
A number that can make and receive calls, starting with 090, 080 or 070, is usually needed to open a Japanese bank account, apply for jobs, sign a rental contract and register at many offices. In other words, it is often the key that unlocks the rest of your setup, including the bank account that may later lead to a Japanese credit card.
If you know you will need these things soon, it can save time to go straight to a plan with a callable number once your documents are ready. If you are not sure, describe your plans to support and they can help you decide whether a data-only option is enough for now.
Identity verification: what to prepare
Plans with a callable number need identity verification before activation. This is standard in Japan for phone numbers. Usually you need a valid residence card, your current address in Japan and a payment method in your own name. Staff explain every step before you send anything, so you know what is being asked and why.
Some providers require reading the IC chip inside your residence card using your phone's NFC function. If that applies to your plan, staff tell you in advance and guide you step by step. If your phone cannot read the chip, there is a fallback, so an older phone does not automatically block you.
To make this stage smooth, check that the address on your residence card matches where you live now, keep the card nearby when you start, and make sure the payment method you agreed on is in your own name. Small mismatches are the most common reason for delays, and they are easy to fix before you begin.
Prepaid or monthly: picking the payment style that fits
Beyond the three main plans, the wider catalogue includes prepaid SIM and eSIM options for 3 to 12 months. You pay once and there is no monthly fee. This can suit students on a fixed term or anyone who prefers to settle the cost upfront rather than think about monthly charges.
There are also monthly data and voice SIM and eSIM plans on the Docomo, SoftBank and Rakuten networks, plus an AU option meant for home Wi-Fi. Monthly plans suit people staying longer who want flexibility. The current price for each option is shown on the plans page, so check there rather than relying on figures you have seen elsewhere.
Whichever you choose, any minimum term or cancellation fee is confirmed clearly before sign-up is finished. Nothing is hidden in fine print. If something is unclear, ask before you confirm.
Frequently asked questions
Can I really get a Japanese SIM without a Japanese credit card?
Yes. For shibaSIM resident plans, a Japanese credit card is not required. Staff confirm a payment method that works for you in chat before you pay anything, so you know where you stand from the start.
I do not have my residence card yet. What should I do?
Use a travel eSIM for your first days. It needs no documents and you can pay with a card from home. Once your residence card and address are ready, you can move to a monthly or prepaid resident plan.
Will SMS verification codes work on my plan?
Only plans that explicitly include SMS can receive text messages, such as the Work plan and the Japanese phone number plan. Even then, delivery of verification codes depends on the app and the sender, so it is not guaranteed for every service.
I already have a Japanese number. Can I keep it?
Yes, through an MNP transfer. You need an MNP transfer code from your current carrier. Do not cancel your old contract first, or the number will be lost.
The takeaway
Not having a Japanese credit card does not have to keep you offline. Start with a travel eSIM if your documents are not ready, then choose a resident plan based on whether you need data only, SMS or a real Japanese number. If you want to compare options or ask about payment before committing, take a look at SIM and eSIM plans for living in Japan and send the team a message with your situation.
