Key correction: Debunking the “You Can’t Open an Account Before 6 Months” MythExperience
Many international students who have just arrived have heard the claim, “Foreigners cannot open a bank account at all until they have been in Japan for 6 months,” and are so intimidated that they do not even try. This is incorrect; it needs to be understood on two levels.
First, the concept of “6 months” does exist, but it comes from the Foreign Exchange and Foreign Trade Act’s determination of “resident/non-resident” status. Ministry of Finance notices and directives state that foreigners are generally treated as “non-residents,” but people employed by an organization in Japan or those who have been in Japan for 6 months or more may be presumed to be “residents.” This is a status framework for foreign exchange control, not a ban on opening bank accounts.
Second (and crucially), whether you can successfully open an account is not determined solely by this concept under the Foreign Exchange Act, but by each bank’s own risk-control rules (KYC/AML). So, in practice, some banks will let you open an account (Japan Post Bank is often the most realistic option), some will ask you for additional documents (major city banks often get stuck on requirements such as a “residence card issued before renewal”), and some may effectively block your application.
Practical takeaway: Don’t give up trying just because of this claim. The best approach is to complete your resident registration (転入届), then try Japan Post Bank first with your residence card and student ID/enrollment certificate. When your school, scholarship, or part-time job has specific banking requirements, consider whether you need to open a second account. At the same time, don’t go to the other extreme and assume that “any student can definitely open an account”—you can still be turned away if your residence card is close to expiring, you do not have proof of enrollment, or the address on your documents does not match.

Overall Account-Opening Strategy (From an International Student’s Perspective)Experience
- Recommended order: first complete resident registration (転入届) → try opening a ゆうちょ account with your student ID → then check whether your school’s designated bank, scholarship, or part-time job requires a second account.
- For someone who has just arrived, is a full-time student, has not started a part-time job, and has no previous residence card, ゆうちょ is often the most realistic option. City banks (みずほ/SMBC) and some online banks tend to require more documentation.
- As an international student, all you really need is the three-piece set: 「普通預金口座 + キャッシュカード + ネットバンキング」 (ordinary deposit account + cash card + online banking). Do not be talked into fixed-term deposits or investments.
- A personal seal (印鑑/ハンコ) is not a prerequisite for opening an account. Japanese financial institutions have widely adopted 「印鑑レス/印鑑不要」 (seal-free/no seal required) procedures (SMBC’s web account, for example, is seal-free). If an institution specifically requires one, a simple seal at the 「認印」 level is enough.
- Do not make 「today I must get an account」 a hard target. Try soon after resident registration, but it often cannot be opened that day, so leave room for repeat visits to the counter.
- Salary deposits (給与振込), scholarships, and tax refunds all require an account in your own name. That is the main reason to open an account soon after arrival; phone contracts and payment services also often get stuck without one.
- A hard safety rule: never lend your account or card to someone to “route transactions through it for a fee.” Buying or transferring bank accounts (口座売買·譲渡) is a criminal offense in Japan and can facilitate money laundering or fraud; it can also affect your residence status.
