Choosing a Japanese Language School in Japan: What to Check Before You Apply
Updated: 2026-09-16
Quick answer
Hi, I'm Miya, and I help newcomers settle into life in Japan. This guide is for people still at home who are thinking about coming to study at a Japanese language school on a student visa. It covers how to compare schools before you apply — not what to do after you land, and not how to study once you're here. I won't rank or recommend particular schools; the aim is to help you ask the right questions.
The short version: first make sure the school is one that can accept students on a student visa, since that is the foundation for everything else. Then compare the practical things — the school's track record, course length and intake months, location, class size and nationality mix, and housing support. Finally, work backwards from your preferred start date, because the application and the Certificate of Eligibility process usually take several months.
First, check the school can sponsor a student visa
Not every place that teaches Japanese can bring you to Japan on a student visa. For that, the school generally needs to be recognised under Japan's framework for Japanese language education institutions, and that framework has been changing: a newer certification system was introduced recently, with a transition period for schools that were already accepting international students.
Because the standing of individual schools can shift during a transition like this, I'd avoid relying on a brochure or an agent's word alone. Check the current information on the relevant government pages — the Ministry of Education, Culture, Sports, Science and Technology and the Immigration Services Agency both publish information about recognised institutions — and ask the school directly how its status stands today.
Look at the track record and the classroom
Once you know a school can accept you, look at how it actually runs. Useful questions include what students typically go on to do after finishing — university, vocational school, work or returning home — how the school handles attendance, and what support it offers for exams such as the JLPT or for applications to further study. A school that answers these clearly and in writing is usually easier to trust than one that only offers general promises.
Class size and the mix of nationalities also shape your day-to-day experience. Smaller classes can mean more speaking time, and a varied mix means Japanese becomes the shared language in and out of class, while a school where many students share your first language can feel reassuring at the start. Neither is right or wrong — ask for typical numbers and think about which environment suits the way you learn.
Course length and intake months
Courses for student-visa holders usually run from around one year up to about two years, and schools build the lengths they offer around their intake months. Many schools take new students a few times a year — spring and autumn intakes are common, and some also start in summer or winter — but this varies from school to school.
The right length often depends on your goal. If you plan to move on to a university or vocational school in Japan, check whether the course end date lines up with their entrance timing. If you want a shorter experience, confirm that the course you choose is one the school can sponsor on a student visa, as shorter programmes may be handled differently.
City or regional: where to study
Big cities offer lots of schools, easy transport and plenty of part-time job listings, but rent and daily living costs are often higher, and it's easy to slip into speaking your own language with friends. Schools in regional cities and smaller towns can mean lower living costs, a calmer pace and more everyday chances to use Japanese with locals.
Think about life outside class, too. If you plan to work part-time, remember that students generally need separate permission for this and the hours are limited, so check the rules with the Immigration Services Agency rather than counting on a particular income. It's also worth looking at how far the school is from likely housing, and what the seasons are like in that area.
Dormitories and housing support
Finding an apartment from abroad can be hard, so many prospective students look closely at housing support. Some schools run dormitories or shared housing, some work with housing partners, and some simply help with introductions once you arrive. Ask what's included, whether rooms are private or shared, how long you can stay, and what the move-in costs and contract terms look like.
Many students stay in school-arranged housing for the first few months and then move to their own place once they know the area. If that's your plan, ask whether the school can help with that later step too, since renting in Japan often involves a guarantor or a guarantor company and paperwork in Japanese.
The application timeline and the Certificate of Eligibility
For a student visa, the usual path is that you apply to the school, the school checks your documents, and then it applies to the Immigration Services Agency for a Certificate of Eligibility on your behalf. You'll typically be asked for things like academic records, proof of Japanese study, and documents showing how your tuition and living costs will be covered, often with a financial sponsor. Schools generally set application deadlines several months before each intake.
If the Certificate of Eligibility is issued, the school sends it on to you and you apply for your visa at a Japanese embassy or consulate in your country. Because each step takes time and requirements vary by nationality and school, start early, keep copies of everything and follow the school's own schedule — and check the Immigration Services Agency's current guidance for the latest process.
After you land: a Japanese phone number
Before you arrive, your school will usually keep in touch with you and your sponsor or guarantor by email. Once you land, though, you'll quickly need a Japanese phone number — the school, part-time job applications and apartment contracts tend to ask for one, and many sign-ups send verification codes by text. That's something you arrange after your residence card is issued — at several major airports that happens on arrival — rather than before you leave home.
Having a Japanese phone number with data sorted early makes those first weeks much smoother. It's refreshingly simple — you apply online with your residence card, verify with a quick eKYC, and eSIM-capable phones can connect the same day, often within about fifteen minutes. Have a look at our setup guide for eligibility and the step-by-step, and confirm current terms on the page before you apply. Choose your school carefully, and I'll be right here to help once you arrive.
