Can international students work in Japan?

International students in Japan on the "Student" status of residence are allowed to take part-time work, but only under specific conditions and only after getting official permission. The "Student" status itself is granted for study, so any paid work is treated as an activity outside that status and must be authorised.

This matters because working without the correct permission, or beyond the allowed limits, is a violation that can lead to penalties and even affect your ability to stay in or return to Japan. The rules exist to keep study as your main activity.

This guide explains the framework in plain terms. It is general information, not immigration advice, and the details can change — always confirm the current rules with the Immigration Services Agency (ISA) and official Study in Japan information.

The permission you must obtain first

Before you take any paid part-time job, you must obtain "permission to engage in an activity other than that permitted under the status of residence previously granted". You can typically apply for this permission when you arrive at the airport or seaport as a new student, or afterwards at a Regional Immigration Services Bureau.

Once granted, this permission is what legally allows a student to do part-time work within the set limits. Without it, working is not permitted — even a casual job.

Keep proof of your permission, and re-check the requirement if your circumstances change (for example, a change of school or status). Confirm the exact application method and any conditions on the ISA official site.

The hours limit: about 28 hours a week

With permission granted, students are generally limited to a maximum of about 28 hours of work per week. During the institution's officially designated long holiday periods, the limit is higher — commonly stated as up to 8 hours per day.

The weekly cap usually applies across all your jobs combined, not per employer, so if you work more than one job you must add the hours together. The purpose of the cap is to ensure work does not interfere with your studies.

Because the exact figures and how they are counted are set by immigration rules and can change, treat "28 hours a week" and "8 hours a day in long holidays" as the widely stated figures and verify the current limit on the Immigration Services Agency and Study in Japan sites before relying on it.

What work is and isn't allowed

The permission covers general part-time work within the hours limit, but not everything. Certain categories of work are prohibited for students — in particular, jobs in the adult-entertainment and related "businesses affecting public morals" sector are not allowed, regardless of the role.

Your work must also remain genuinely part-time and secondary to study; it cannot become effectively full-time employment under a student status. Some universities additionally advise students on suitable roles and hours.

If you are unsure whether a specific job is allowed, check official guidance rather than assuming. The ISA and Study in Japan sites set out the prohibited categories and conditions.

Staying compliant: study first, keep records

Three habits keep you on the right side of the rules: get permission before you start, track your total weekly hours across all jobs, and keep attendance and academic performance up. Immigration and schools treat study as the priority, and poor attendance can affect visa extensions.

Official sources warn that breaking the conditions may result in penalties and even affect your ability to remain in Japan, so the stakes are real. Do not let an employer push you past the hours limit or into prohibited work.

Whenever your situation changes, re-verify the rules. This is general information, not immigration advice — the Immigration Services Agency is the authority on what is currently allowed.

How this fits your budget

Part-time work can help with living expenses, but it is a supplement, not a substitute for proper funding. Official Study in Japan information is explicit that students cannot cover all their tuition and living costs from part-time work alone, given the hours cap and typical earnings.

So when you budget, plan for tuition and living costs to be met mainly by savings, family support and scholarships, with part-time earnings as a top-up. Avoid any plan that depends on working the maximum hours every week.

For the current hours limit, permitted work and application procedure, always check the official Immigration Services Agency and Study in Japan pages for the year you are studying.

Frequently asked questions

How many hours a week can a student work in Japan?

Generally up to about 28 hours per week once you have the required permission, with a higher limit (commonly stated as up to 8 hours a day) during officially designated long holidays. The cap usually applies to all jobs combined — verify the current figure with the Immigration Services Agency and Study in Japan sites.

What permission do I need to work part-time?

You must obtain permission to engage in an activity other than that permitted under your status of residence. You can apply on arrival at the airport as a new student or later at a Regional Immigration Services Bureau. Without it, part-time work is not allowed.

Are any jobs off-limits for students?

Yes. Work in the adult-entertainment and related "businesses affecting public morals" sector is prohibited for students, and work must stay part-time and secondary to study. Check the official ISA and Study in Japan guidance if you are unsure about a specific job.

What happens if I break the rules?

Working without permission or beyond the limits is a violation that official sources say may lead to penalties and can affect your ability to stay in Japan and your visa extensions. Keep within the hours, avoid prohibited work, and maintain good attendance.

Can I fund my studies through part-time work?

No. Official information states part-time work alone cannot cover all tuition and living costs, because of the hours cap and typical earnings. Plan your finances around savings, family support and scholarships, with part-time income only as a supplement.
