A Certificate of Eligibility (COE) is the document at the centre of Japan's student visa process. It is issued by a regional bureau of the Immigration Services Agency, under Japan's Ministry of Justice, and certifies that you meet the legal conditions to live in Japan as a student. Importantly, the COE is not the visa itself — it is the evidence you use to obtain one.
How the process works, step by step
The order matters, and most of the first step is handled for you:
- Step 1 — Your school applies for the COE. Once you are accepted, your university or Japanese language school submits the COE application to its local Immigration Services Agency office on your behalf. You supply the supporting documents — passport, photos, academic records and proof of funds.
- Step 2 — You apply for the visa. After the COE is issued, your school posts it to you. You then take the COE, your passport, the visa application form and a photo to the Japanese embassy or consulate in your home country. The visa is usually issued within about 5–7 working days.
- Step 3 — You enter Japan. You show the COE and visa on arrival and are issued a Residence Card (在留カード).
How long the COE takes
Processing depends on the region and the time of year. Tokyo Immigration typically takes around 4–8 weeks, while the Osaka and Nagoya offices average about 3–6 weeks. Because demand spikes before the April and October intakes, schools generally advise submitting the COE application at least two months before your course start date — file it too late and you risk missing the semester.
Financial requirements
A COE is only granted if you can show enough money to cover tuition and living costs without relying on part-time work. In practice, applicants are usually asked to evidence in the region of ¥2 million in savings (or a sponsor who can), along with documents explaining where the funds came from. Living costs outside Tokyo commonly run about ¥120,000–¥150,000 per month.
Working while you study
A student residence status does not include the right to work by default. To take a part-time job you must first obtain “Permission to Engage in Activity Other Than That Permitted” (資格外活動許可) — you can request this at the airport when you first arrive, or later at an immigration office. With it you may work up to 28 hours per week during term, and full-time (up to 8 hours a day) during official long university holidays. Work in the adult-entertainment industry is prohibited regardless of hours.
After you graduate
Students who need more time to find a job can switch to a job-hunting Designated Activities visa, valid for six months and extendable once, for up to a year of searching — and you can keep working 28 hours a week during it. Once you have an offer, the common routes are the Engineer / Specialist in Humanities / International Services work visa or Specified Skilled Worker (SSW) status.
Who studies in Japan
Japan is an increasingly popular destination for students from Nepal, Vietnam and Bangladesh, many of whom begin at a Japanese language school before progressing to a university or vocational college. A good education consultant can line up the school acceptance, the COE paperwork and the proof-of-funds documents so the timeline does not slip.
Rules and figures are set by Japan's Immigration Services Agency (Ministry of Justice) and can change — confirm current requirements with your school or the nearest Japanese embassy before you apply.
