How to receive technical intern training?

If you submit an application to the sending agency in your home country and pass the interview of the host company in Japan, you will enter Japan after receiving Japanese language and other education. In Japan, the host company prepares the housing (dormitory) for the trainee, and if the trainee has a problem in work or everyday life, the union (supervising organization) in addition to the host company provides support. In many cases, the union is run by cooperatives.
Flow of technical intern training (Example in Vietnam)
This section describes the overall flow of the technical intern training.
The technical intern training involves the sending agency in your home country and the union in Japan.
*It depends on the country.
*There is also a company-wide technical training program in which employees of overseas subsidiaries receive training at the parent company in Japan.
(1) Union looks for a job offer
- A Japanese union receives a job offer from a host company.
- When the union receives a job offer, it asks a foreign sending agency to introduce a candidate for the technical intern training.
(2) The sending agency introduces job information to the candidate
- The sending agency is always looking for technical intern trainee candidates.
- It will introduce the information of the job offered by the Japanese union to the candidates.
(3) Interviews and acceptance
- Candidates who apply for the job are interviewed by the host company (or union) at the sending agency in their home country, and if they pass, they are hired as technical intern trainees.
(4) Pre-education and departure to Japan
- Successful applicants receive Japanese and other education (often for three to six months) from the sending agency before entering Japan. They usually take classes at a Japanese language center as boarding students. They will also be supported in obtaining status of residence (visa).
*Some sending agencies provide thorough education before the interview.
(5) Orientation and training after arrival
- The union in Japan gives the trainees lectures on Japanese language and life in Japan for more than a month.
(6) Technical intern training starts!
- Technical intern training begins at the host company.
Roles of the union
During the technical intern training period, the union has the following roles:
- Checking that the host company is conducting appropriate technical intern training and reporting findings to the immigration office (at least once every three months)
- Visiting the host company at least once a month for mentoring (if there are first-year trainees)
- Giving advice to trainees in their native language about the contents of the technical intern training, treatment, and lifestyle
There are many trainees who live a fulfilling life in Japan and send enough money to their home countries. However, there are cases of host companies causing problems such as violence, abusive language and not paying for overtime work. In such cases, trainees should consult with the union first, but if that proves unsuccessful, they should contact OTIT (Organization for Technical Intern Training). OTIT has the strong authority to give directions to unions and host companies.
