There is an increasing number of cases where spouses staying in Japan on a “Dependent” (Kazoku Taizai) visa, who are currently working part-time with permission, are asked by their employers to become full-time employees, or successfully secure a job offer from a Japanese company through their own job hunting.
While this is a significant step forward in one’s career in Japan, under the practical application of the Immigration Control Act, it is not as simple as saying, “I got a job offer, so I can start working full-time tomorrow.” This article thoroughly explains the legal barriers that a spouse on a Dependent visa must overcome to work full-time, and the lawful procedures required to eliminate the risk of illegal labor.
1. The Limits of the Dependent Visa: The “28-Hour Rule” and the “Premise of Support”
First, it is necessary to accurately understand the legal nature of your current “Dependent” visa. This status of residence is granted on the absolute premise that you are “living under the financial support” of the primary visa holder (who holds a work visa such as Engineer/Specialist in Humanities/International Services).
Full-Time Work Destroys the “Premise of the Visa”
If you have obtained “Permission to Engage in Activity Other Than That Permitted Under the Status of Residence,” working is allowed, but it is strictly limited to part-time work of “up to 28 hours per week.” Working full-time (e.g., 40 hours a week) as a regular employee not only clearly exceeds this time limit, but also means that the spouse will earn enough income to make an independent living.
Under the Immigration Control Act, this represents a deviation from the “state of being supported,” collapsing the fundamental premise of the Dependent visa. Therefore, in order to work full-time, it is a legal obligation to apply for a Change of Status of Residence from your current “Dependent” visa to an independent work visa, such as “Engineer/Specialist in Humanities/International Services.”
2. The Biggest Hurdle: The “Education” and “Job Duty” Barriers
Even for a spouse already residing in Japan, the application to change to a work visa is subject to the exact same extremely strict screening criteria as bringing a new foreign national from abroad. No matter how highly the company evaluates your personality or Japanese language skills, approval will not be granted unless the following objective requirements are met.
Barrier 1: The Absolute Nature of the Education Requirement
The first hurdle to obtaining a work visa (Engineer/Specialist in Humanities/International Services) is your educational background. In principle, the spouse must meet one of the following requirements:
- Have “graduated from a university (including junior colleges)” in their home country or in Japan.
- Have “completed a specialized course at a vocational school (Senmon Gakko)” in Japan and been awarded the title of “Diploma” (Senmonshi).
If your highest level of education is a “high school diploma,” it is generally impossible to change to a work visa unless you can prove 3 to 10 years of relevant work experience (depending on the job duties) with objective documentation.
Barrier 2: Logical Consistency Between “Major” and “Job Duties”
Even if you clear the education requirement, the next barrier awaits. There must be a logical correlation between the “academic subject you majored in at university” and the “actual job duties you will perform at the company.”
For example, if someone who majored in “Literature” works as a “Programmer” at an IT company, the correlation cannot be proven, and the application is highly likely to be denied. Furthermore, for job duties considered “simple manual labor”—such as working as a cashier at a supermarket, a hall staff member at a restaurant, or doing line work in a factory—a work visa will not be granted, regardless of how high your educational background is.
3. Practices to Prevent Illegal Labor: The “Ironclad Rule” for Contracts and the Transition Trap
In the procedure to change to a work visa, the most common legal troubles occur regarding the handling of the “transition period (while the application is pending).”
Working Full-Time Before Approval is “Illegal”
Even during the period when you have submitted an application for a Change of Status to the Immigration Bureau and are waiting for the result, your current status is still “Dependent.” Therefore, starting to work more than 28 hours a week simply because “I already applied” or “the company told me to come in early” is a violation of Article 19 of the Immigration Control Act. This constitutes illegal labor. In the worst-case scenario, not only the applicant but also the employing company may be charged with facilitating illegal labor, facing the risk of visa revocation and deportation.
Signing an Employment Contract with a Condition Precedent
To prevent this situation, it is an ironclad rule in practice that when signing an employment contract with a company, you do not fix the joining date to a specific day. Instead, you must include a clause (condition precedent) stating: “This contract shall only take effect if and when the Party B (the worker) is granted a change of status of residence that permits employment.”
4. Alternative Approaches When the Education Requirement Cannot Be Met
If the spouse only has a high school diploma from their home country and cannot meet the educational requirements for the standard work visa, should they give up on full-time employment? In practice, the following alternative approaches can be considered:
- Transition to a “Specified Skilled Worker” (Tokutei Ginou) Visa: This is a work visa with no educational requirements. If you pass the “Skills Evaluation Test” and the “Japanese Language Test (N4 or higher)” in designated fields such as food and beverage manufacturing, restaurant industry, or nursing care, full-time employment is possible.
- Working “Like a Full-Timer” Within the Time Limit: This option involves maintaining the “Dependent” visa and aiming for a position with a high hourly wage and good benefits (such as a contract employee) while staying strictly within the 28-hour per week limit and enrolling in social insurance.
5. Practical Q&A: Changing from Dependent to Work Visa
- Q: I have been working in customer service at my part-time job for a long time, and I was offered a full-time position as a store manager candidate. Can I change my visa?
A: If the main duties are on-site labor such as customer service and cashiering, changing to a standard work visa is extremely difficult. However, if “management duties” (e.g., store sales management, staff labor management, marketing) make up the majority of your work, and this perfectly matches your university major (e.g., Business Administration), it is possible to get approval by proving this with a detailed statement of reasons. - Q: My husband (the primary visa holder) is currently unemployed and job hunting. Can I change my visa to work full-time to support the household?
A: The screening for a work visa is entirely based on the consistency between the spouse’s educational background and their job duties at the company. The household’s economic situation is not a factor in the screening. You can change your visa if you meet the requirements, but maintaining your husband’s visa status will become a separate issue. - Q: How long does it take from application to result? Can I work up to 28 hours during that time?
A: The standard processing time for a Change of Status application is roughly 2 weeks to 1.5 months. Until the result is issued, you are legally permitted to continue working as long as it is within the scope of your current “Dependent” visa’s work permit (up to 28 hours per week).
Transitioning a spouse to a full-time employee is an effective way to improve household income and career prospects, but it is necessary to calmly assess in advance whether the strict criteria of the Immigration Control Act are met. Before signing an employment contract, objectively evaluating the compatibility between your educational background and job duties, and constructing a logical application process without contradictions, is the most certain path to eliminating the risk of denial.
