Aisin Factory Vacancies in Aichi tend to centre on two hands-on jobs that suit people who like machines and precision: the machine operator who keeps equipment producing good parts, and the inspector who makes sure nothing faulty leaves the plant. AISIN Corporation is a Toyota-group maker of drivetrain and body parts, and its group companies hire contract staff for production, in-plant work, machine operation and inspection. If you hold an ITI certificate, have worked a lathe or a press, or simply have a sharp eye for detail, these two roles are worth understanding before you apply.
Aisin’s world is Aichi Prefecture, the centre of Japan’s car industry. Recent listings point to two group plants in particular: Aisin Siroki’s plant in Toyota City and Aisin Kiko’s Kira plant in Nishio, in the south of the prefecture. Both sit within easy reach of Toyota’s own assembly plants and of other suppliers such as Denso, so experience gained at one Aisin group site is easily understood across the wider industry. Readers should note that Aisin’s full list of its own plants was not verified for this article, so check the official careers pages for exact locations.
For foreign nationals, machining and inspection in auto parts manufacturing fall within Japan’s Specified Skilled Worker (SSW) field for Industrial Products Manufacturing (工業製品製造業分野), which includes a machining and metalworking category. A machine operator or inspector job may potentially fit this field, depending on exact duties, occupational classification and whether the employer is an eligible manufacturer. Residents with a status that allows any kind of work — for example permanent residents, spouses of Japanese nationals or long-term residents — may also apply for contract posts.

- Watch machine screens for alarms, spindle load and cycle counts
- Measure sample parts with calipers, micrometers, bore gauges and height gauges
- Adjust offsets or call a setter when dimensions start to drift
- Replace cutting tools at set intervals and log the change
- Inspect surfaces for burrs, scratches, cracks and missing features
- Separate defective parts and tag them for review

Aisin Factory Vacancies in Aichi Jobs for Foreign Workers
The SSW (i) Industrial Products Manufacturing field covers auto parts manufacturing, and since June 2026 it has 17 business categories. Machining and metalworking (機械金属加工) is one of them and is the closest match to machine operator work, while inspection tasks are usually part of the same production category. SSW workers in this field must be hired directly by a manufacturer that belongs to JAIM; dispatch employment is not allowed. The government cap for SSW (i) in this field is 199,500 through March 2029.
Machining is also one of the three categories where SSW (ii) is available, which means skilled operators may have a longer-term path if they pass the SSW (ii) test and the Business Career Test Grade 3, or Technical Skill Test Grade 1, and build workplace experience.
Aisin group companies have not been verified as recruiting directly from overseas or sponsoring visas, so applicants should not assume every vacancy qualifies. Confirm the accepted residence statuses with the employer, never pay an unlicensed agent for a “placement”, and remember that a job ad is not a visa guarantee.
Japanese Language Requirement
Machine and inspection work depends on reading numbers, symbols and instructions correctly, so basic Japanese literacy matters.
- Reading part numbers, inspection items and tolerance symbols
- Understanding machine alarm messages in Japanese
- Recording measurement results on Japanese check sheets
- Explaining a defect or abnormality to the leader
- Following safety rules around rotating machinery and presses
SSW (i) applicants need JFT-Basic A2.2 or above, or JLPT N4 or above, and a pass in the Manufacturing SSW (i) skills evaluation test run by JAIM at Prometric centres, or an alternative such as Technical Skill Test Grade 3 or completion of Technical Intern Training (ii).
Eligibility
- A residence status allowing the job, or eligibility for SSW in manufacturing
- Good near vision and colour recognition for inspection
- Steady hands and patience for precise measurement
- Fitness for standing work and lifting moderate weights
- Readiness for rotating shifts
- Basic Japanese reading
- Passing the employer’s interview and health check
Education Qualification
Most Aisin group production roles accept school-level education, but technical training makes a clear difference for operators and inspectors.
- 10th pass for in-plant production staff
- ITI Machinist, Turner, Fitter, Machinist Grinder or Tool and Die Maker is strongly relevant
- Diploma in Mechanical or Production Engineering helps for inspection and setting
- Short courses in CNC operation or metrology add value
Daily Work of an Aisin Machine Operator

- Change worn tools at the planned count and record the change.
- Hand questionable parts to the inspector and hold the batch if needed.
