Is Side Work Allowed Without Permission? | MyKyoten

You've been offered some freelance work on the weekends. Maybe a friend needs help with a translation project, or someone wants you to teach a few private English lessons. The money would be helpful, the work sounds interesting, and it won't interfere with your main job. So can you just accept it and get started?

The answer depends on your visa type and the specific activity involved, not on how much money you'll earn or how many hours you'll work. This connects to broader reporting and compliance requirements. Many people assume that small side jobs don't matter to immigration, or that earning under a certain amount means you don't need permission. That's not how the system works. Any paid activities outside the scope of your current visa require separate permission, regardless of income size.

If you search online for information about side work in Japan, you'll find a frustrating mix of advice. Some people say you need permission for everything. Others claim you can do whatever you want as long as it's similar to your main job. Both perspectives contain some truth, but neither applies universally.

The problem is that advice often lacks context. Someone might share their experience getting permission for freelance work, but they don't mention they're on a different visa category than you. General statements like "side work is fine" or "you always need permission" are both oversimplifications.

On the Engineer/Specialist in Humanities/International Services visa, you can do side jobs covered by the scope of the visa without having to get permission. This could include engineering work for another company, teaching programming, writing technical articles, or translation work. However, if you are in Japan on the Highly Skilled Professional visa, you need to get permission from immigration to do anything that isn't your main gig.

Understanding What Requires Permission

The key distinction is whether the side work falls within the scope of activities already permitted under your visa. If you're on an engineering visa and you take on some part-time programming work, that stays within your approved scope. These activities don't require separate permission because they're already covered by your visa category.

But if the side work falls outside your visa scope, you need Permission to Engage in Activities Other Than Permitted. Holders of a work visa are generally not eligible to obtain this permission for simple part-time jobs, such as cashiering, waiting tables, or packing. Work visas are for professional activities, and unskilled labor falls outside that framework entirely.

There are also important limitations even when permission is granted. The working hours under this permission must not exceed the number of hours you spend on your main activity. In general, it's considered reasonable to keep side work hours within half of your main job hours. Your side work also cannot interfere with your primary employment.

The safest approach is to identify the activity clearly before accepting any side work. What exactly will you be doing? Does it fall within the scope of your current visa category or outside it? If you're not sure, that uncertainty itself is a signal that you should check with immigration before proceeding.

You also need to check your employment contract. Many companies in Japan have policies about side work, and some prohibit it entirely or require approval from your supervisor or HR department. Even if immigration would permit the activity, violating your employment contract could get you fired, which then jeopardizes your visa status anyway.

If your side work falls outside your visa scope, you need to apply for Permission to Engage in Activities Other Than Permitted before you start working. You must reapply each time you change your part-time job that is permitted under this permission. In addition, you are required to reapply whenever you renew your current visa status if you wish to continue the activities permitted under this permission.

Immigration reviews your tax records, income sources, and employment history during renewal applications. Inconsistencies between your reported income and your stated employment can trigger questions. Unreported side work discovered during a renewal review creates compliance issues that are much harder to fix after the fact than if you'd obtained proper permission from the start.

Whether side work is allowed without permission depends entirely on your visa type and whether the activity falls within your approved scope.

Income amount doesn't determine whether permission is needed.

The few hours spent clarifying the rules now prevents serious problems later.

Submit an application at your regional immigration office. Processing takes approximately 2 weeks. You can also request it at the immigration counter when entering Japan on a dependent visa, where it is often granted on the spot.

Dependent visa holders with work permission are capped at 28 hours per week total across all jobs combined. This limit applies whether you have one part-time job or multiple. Exceeding it risks visa revocation at renewal.

Any paid activity outside your primary visa-permitted employment counts as side work. This includes freelancing, tutoring, content creation for pay, and part-time work at a second employer. Unpaid volunteer work is generally not subject to the restriction.

What happens if you work a side job without permission in Japan?

Working without permission is a visa violation that immigration can discover through tax records and employer filings. It can result in visa denial at renewal and in serious cases revocation of your current visa status.
