Studying in Japan for more than 90 days means going through a two-stage process most other countries don't use: your school first applies on your behalf for a Certificate of Eligibility (COE) inside Japan, and only once that's issued do you apply for the actual student visa at a Japanese embassy or consulate in your home country. It's a system that rewards early paperwork and punishes last-minute applications, so understanding the sequence matters as much as the individual requirements. Immigration rules and figures below reflect the sources reviewed and can shift, so always confirm current details with Japan's Immigration Services Agency (ISA), the official Study in Japan portal, or your nearest Japanese embassy or consulate before you apply.
This guide covers who needs a student visa, how the COE process works, the financial proof you'll be asked for, the full document checklist, application timelines, and what you're allowed to do — in terms of work — once you're in Japan.
The Visa/Permit: Certificate of Eligibility Then Student Visa
Foreign nationals planning to study in Japan for more than about three months need what's officially called the "Student" status of residence, applied for as a student visa. Getting there involves two distinct steps:
| Stage | Who handles it | What happens |
|---|---|---|
| 1. Certificate of Eligibility (COE) | Your school (acting as your proxy) applies to Japan's Immigration Services Agency | Confirms you meet the basic requirements to hold "Student" status; typically takes several weeks to a few months |
| 2. Student visa | You apply at a Japanese embassy or consulate in your home country, using the issued COE | The embassy stamps your passport with the visa; you cannot switch a COE into a visa from inside Japan |
You cannot skip straight to a visa application without a COE in most cases — while it's technically possible to apply without one, doing so requires submitting a much larger set of verification documents and can take several months longer, and consulates strongly discourage it. If you're still choosing where to apply, TheUniFinder's universities in Japan listings and scholarship finder can help you shortlist programs before you start the visa paperwork.
Eligibility & Key Requirements
To be issued a COE and then a student visa, you'll generally need to show:
- Confirmed enrollment at a Japanese university, vocational school, or language school that will act as your COE sponsor/proxy.
- Proof of academic background relevant to your program — transcripts, diplomas, and, depending on the program, language test scores (Japanese-Language Proficiency Test/JLPT results) or English proficiency evidence.
- Proof of financial ability to cover tuition and living expenses for your stay (detailed below).
- A valid passport, generally required to remain valid beyond your intended length of stay.
- For some nationalities, a tuberculosis (TB) clearance certificate obtained from a designated panel clinic before the COE application deadline.
Exact requirements can vary depending on your school, your nationality, and your program type (degree program, exchange, or language school), so always confirm the specific checklist with your school's international office.
Timing matters more in Japan's system than in most countries because the COE stage runs on its own clock, separate from your school's admissions deadline. Many universities and language schools publish COE application windows tied to intake season — for example, opening a form in the months before a fall, spring, or summer start and closing it well ahead of the semester — precisely because immigration needs that lead time to process the certificate. Missing your school's internal COE deadline, even if you're otherwise eligible, can push your entire enrollment back a full intake cycle, so check your school's specific calendar as soon as you accept your offer.
Proof of Funds
Japan doesn't set one fixed, universally published minimum bank balance for students — the Immigration Services Agency doesn't mandate a specific figure — but schools commonly advise a working benchmark so applicants have a realistic target. Many institutions suggest that self-sponsored ("self-sponsor") applicants show accessible funds in the region of ¥2.5 million to ¥3 million (roughly equivalent in your home currency), while a sponsor supporting you financially is often expected to show a bank balance of a similar magnitude — figures reported by individual schools have cited around ¥3,000,000 as a reference point.
Whatever the amount, your financial documentation needs to:
- Clearly show where the funds are coming from (your own savings, a family sponsor, a scholarship, or a loan).
- Be dated recently — typically within the last three months of your application.
- Be submitted alongside a letter or form identifying the sponsor and their relationship to you, if someone else is funding your studies.
Because there's no fixed statutory threshold and expectations vary by school and by case, treat any figure you see as a planning guide rather than a guarantee, and confirm the current expectation directly with your school's admissions or international student office.
Required Documents Checklist
For the COE stage, you'll typically need to prepare:
- Completed COE/student application form provided by your school
- Passport-style photo (usually taken within the last three months)
- Academic records — transcripts, diplomas, language certificates (JLPT or equivalent), as required by your program
- Proof of financial ability — bank statements, savings balance certificates, income statements, or scholarship/financial aid documentation
- A sponsor letter or financial certification form, if someone else is funding you, naming the sponsor and your relationship to them
- TB clearance certificate, if required for your nationality
Once your COE is issued and sent to you, you'll need for the visa stage:
- Valid passport
- Visa application form (from your local Japanese embassy or consulate)
- One recent passport-style photograph
- Original Certificate of Eligibility (a digital copy is often accepted if the hard copy hasn't arrived yet)
- Certificate of Admission from your school
- Any additional documents requested by your specific embassy or consulate
Application Process & Timeline
- Get admitted to a Japanese school that will sponsor your COE application.
- Submit your COE application documents to your school by its internal deadline — the school compiles everything and files it with the regional immigration authority in Japan on your behalf.
- Wait for the COE to be issued. This step commonly takes anywhere from several weeks to a few months, and is the single biggest bottleneck in the whole process — apply as early as your school allows.
- Receive your COE from your school (often as a digital copy first, with the physical original following by mail).
- Apply for your student visa at the Japanese embassy or consulate in your home country (or country of legal residence), submitting your COE along with the visa application form, passport, photo, and Certificate of Admission.
- Pay the visa fee. Fees are commonly cited around ¥3,000 for a single-entry visa and up to ¥6,000 for a multiple-entry visa, though a number of nationalities are exempt from the fee entirely under bilateral agreements — check the current fee-exempt list and amounts with your embassy, since these are revised periodically.
- Wait for visa processing, typically a matter of days to a couple of weeks depending on the embassy.
- Travel to Japan — you're generally permitted to enter up to 21 days before your program's start date. On arrival, immigration issues you a residence card, which functions as your ID in Japan and which you'll need for everything from opening a bank account to signing a phone contract.
Timeline tip: Because the COE stage alone can take one to three months, start gathering your financial and academic documents as soon as you're admitted — don't wait for a formal "start your visa application" prompt from your school.
Working While Studying and After Graduation
Once you're enrolled and holding "Student" status of residence, you can apply for permission to work part-time — commonly capped at 28 hours per week during term time, with fuller hours typically allowed during official school vacations. This work permission isn't automatic: you need to separately apply for a permit to engage in activities outside your original status of residence before taking any part-time job, and working beyond the permitted hours or without the permit can jeopardize your visa status.
Japan also offers post-study options for graduates who want to work, most commonly by switching from "Student" status to a work-related status of residence (such as "Engineer/Specialist in Humanities/International Services") once you have a job offer matching your qualifications, or through the "Designated Activities" status for graduates actively job-hunting for a defined period after graduation. Since eligibility and duration for these routes depend on your specific situation, confirm current post-study options with the Immigration Services Agency or your school's career center well before you graduate.
Common Refusal Reasons and Practical Tips
- Applying too late. Because the COE alone can take months, missing your school's internal deadline can push your entire timeline past your intended start date.
- Weak or unclear proof of funds — documentation that doesn't clearly show the source of the money, or that's older than the accepted window, is a common sticking point.
- Incomplete sponsor documentation — if someone else is funding you, missing the sponsor's income proof or the relationship certification can delay your COE.
- Missing the TB clearance deadline, for nationalities where it's required — this involves an appointment at a designated clinic, so don't leave it until the last minute.
- Working without permission or beyond the 28-hour cap — this can affect visa renewals and future applications, so get the work permit before taking any job.
- Forgetting that a COE cannot be converted into a visa from inside Japan — if you're applying from outside the country, plan your travel around receiving your COE by mail or digitally first.
Frequently Asked Questions
How long does it take to get a Japan student visa? The bottleneck is almost always the Certificate of Eligibility (COE) stage, which commonly takes anywhere from several weeks to a few months to process through Japan's Immigration Services Agency. Once you have the COE, the embassy visa stage itself is typically much faster — often just days to a couple of weeks — but always confirm current timelines with your school and the embassy you're applying through.
What is a Certificate of Eligibility (COE) and why do I need one? The COE is a document issued by Japan's Immigration Services Agency, applied for by your school on your behalf, confirming that you meet the basic requirements for "Student" status of residence. You need it to apply for your student visa at a Japanese embassy or consulate — without it, a visa application is possible in principle but requires far more supporting documentation and can take much longer to process.
How much money do I need to show for a Japan student visa? There's no single fixed amount set by the Immigration Services Agency, but schools commonly suggest self-sponsored applicants show accessible funds in the range of roughly ¥2.5 million to ¥3 million, or that a sponsor show a similar bank balance. Because expectations vary by school and case, confirm the current guidance directly with your school's international office.
Can international students work part-time in Japan? Yes, but only after applying for and receiving permission to engage in activities outside your status of residence. Once approved, students can typically work up to 28 hours per week during term time, with longer hours often allowed during official school breaks.
Can I convert my Certificate of Eligibility into a visa while inside Japan? No. The COE must be taken to a Japanese embassy or consulate in your home country (or country of legal residence) to be converted into an actual student visa — this step cannot be completed from inside Japan.
The figures and timelines above reflect the sources reviewed and can change, so confirm current requirements with Japan's Immigration Services Agency, the Study in Japan official portal, or your nearest Japanese embassy or consulate before applying.
