A structured overview of eligibility, permitted technical work, supporting documents, the Certificate of Eligibility process and residence procedures in Japan.
At a glance
This work status concerns roles requiring specialist knowledge in technology, engineering, the physical sciences, the natural sciences or related technical fields. The proposed duties, the applicant's qualifications and the employing organization are assessed together.
The actual work should require specialist technical or scientific knowledge rather than general or incidental duties.
A relevant course of study, qualifying examination or sufficient related professional experience may support eligibility.
Remuneration should be no less than that offered to a Japanese national performing comparable work.
An applicant generally needs to demonstrate a direct connection between their qualifications or experience and the proposed role. Depending on the circumstances, this may be shown through:
The employment terms also matter. Remuneration should be no less than that received by a Japanese national for comparable work.
Classification matters. Immigration terminology and category boundaries can change. Confirm that the intended duties fall within the appropriate current residence-status framework before preparing an application.
The assessment focuses on what the applicant will actually do in Japan, not simply the job title. Relevant activities commonly require specialist knowledge in areas such as:
A clear job description helps establish the relationship between the role, the employer's business and the applicant's background.
The exact document set depends on the employer category and the circumstances of the application. Typical materials may include:
Documents not issued in Japanese may require Japanese translations. Consistent names, dates, duties and compensation details across the file are important.
Tax and payroll planning: Housing, commuting, overseas compensation and home-leave arrangements can have tax consequences. Review the structure before finalizing employment and application documents. See tax planning for foreign workers in Japan.
For an applicant coming to Japan from overseas, the usual route begins with a Certificate of Eligibility, commonly called a COE. The COE indicates that the proposed activity has been reviewed against the relevant landing requirements.
The application is normally made in Japan by an eligible representative or organization through the immigration procedures available at the time. A COE does not itself guarantee visa issuance or permission to land; those stages involve separate checks.
Processing time varies with the immigration office, employer category, application volume and complexity of the evidence. Avoid relying on a fixed timetable when planning a start date or travel.
Immigration authorities may ask for clarification or additional documents. Prompt, consistent responses can help avoid unnecessary delay. Once issued, the COE should be handled according to the current visa and entry procedures.
After COE issuance, an applicant outside Japan generally uses it when applying for a visa at the appropriate Japanese embassy or consulate. On arrival and completion of entry inspection, the person may be granted the corresponding status and period of stay.
A person already in Japan under another status may need to consider a change-of-status application. Entry as a temporary visitor does not automatically permit a change, and work must not begin until the appropriate authorization has been granted. For background on short stays, read about the Japan visa waiver program.
Eligible mid- to long-term residents receive a residence card through the applicable process. It records key details such as identity, status of residence and period of stay. Residents must follow current rules on carrying the card and reporting changes.
A special re-entry system may be available for qualifying residents who leave Japan temporarily and intend to return within the permitted period while their status remains valid. A standard re-entry permit may be appropriate for a longer absence.
Because the rules depend on the length of absence, passport and residence status validity, confirm the current requirements before departure. Leaving without the correct procedure can affect the existing status of residence.
The holder should continue performing activities covered by the status. A material change in role, employer or duties can create notification or permission requirements.
Observe residence-card, address, employer-change, renewal and notification rules. Start renewal preparation early enough to collect updated employment and tax records.
Employment income is commonly subject to payroll withholding and may also be covered by a year-end adjustment. A separate return may be required where there is overseas income, multiple income sources or another filing trigger. Tax filing deadlines and obligations depend on the person's circumstances.
Citizenship, residence, assets and income can create tax or reporting duties in another jurisdiction. Seek relevant specialist advice where cross-border filing applies.
Departure can require tax settlement, appointment of a tax representative or other notifications. Local inhabitant tax is linked to residence on 1 January, but the consequences vary; obtain advice rather than treating departure timing as a universal tax-saving strategy.

Frequently asked questions
No. The assessment considers the actual duties, the specialist knowledge required and the relationship between those duties and the applicant's background.
Not necessarily. Other routes may include sufficient relevant professional experience or a designated qualification, depending on the current rules and field.
Only work already authorized by the person's current status may be performed. A pending application does not by itself grant permission to start the proposed role.
There is no reliable universal period. Timing varies by office, case complexity, employer category, application volume and requests for additional evidence.
Foreign-language supporting documents generally need appropriate Japanese translations where required by the application process.
Notification and status-scope issues may arise. Confirm the current reporting deadline and ensure the new duties remain within the authorized activities.
