The idea that “a small excess won’t matter” is extremely dangerous. Exceeding the 28-hour weekly work limit for international students in Japan can lead to serious consequences — including visa cancellation and deportation. This article explains the risks and the specific steps both students and employers can take to stay safe.

1. Understanding the Meaning of This Permission

Students holding a student visa are allowed to engage only in activities related to receiving education at a Japanese school. Part-time work is supplementary to studying — not the other way around. The working hour limits exist to ensure that part-time work does not interfere with the primary purpose of the student’s residence in Japan:

• During the school term: up to 28 hours per week
• During school-designated long vacations: up to 8 hours per day

2. Penalties for Exceeding the 28-Hour Weekly Limit

If a student works beyond the 28-hour weekly limit, immigration authorities may determine that what is supposed to be a “supplementary” activity has become the primary activity. If the student is found to no longer be engaging in genuine academic activities, their student visa may be revoked — making continued residence in Japan impossible.

Even if the violation occurs due to carelessness rather than intent, working beyond the permitted scope constitutes illegal employment. In recent years, verification through My Number records and employment data has become more thorough. The idea that “a small excess won’t matter” is extremely dangerous.

Penalties apply not only to the student. Employers who knowingly allow students to exceed the limit — or fail to properly verify their permission — may be charged with aiding and abetting illegal employment under the Immigration Control and Refugee Recognition Act (Article 73-2), which carries significant legal risks.

3. How to Work Part-Time Safely

Check the Type of Business

Before starting a part-time job, make sure it does not fall under adult entertainment businesses. This includes not only sex-related businesses, but also nightclubs and establishments with very dim indoor lighting (10 lux or below).

Track Your Working Hours

Keep your shift schedules and pay statements and check your total working hours on a weekly basis. If you are working at multiple part-time jobs, make sure the combined total across all workplaces stays within 28 hours per week.

Ask Your Employer When in Doubt

If you have any concerns about job duties, shifts, or working hours, confirm the details with your employer. If the explanation is unsatisfactory, choosing a different job is always a valid option.

Part-time work exists to support your academic life in Japan — not replace it. Follow the rules and enjoy a safe, meaningful student experience.
