Job Introduction - Shipbuilding and Ship Machinery Industry

Updated: 2026/5/10

This page provides information useful for choosing a job, such as job types available in the shipbuilding and ship machinery industry, annual income by job type, the current number of workers, and job details.

1. What work in this field means
1-1 Background

The shipbuilding and ship machinery industry is facing difficulty securing workers due to the declining birthrate, diversification of career choices, and other factors, and a serious labor shortage has become clear. As the average age of workers in this field rises, it has become difficult to secure enough workers through domestic human resources alone. This system was introduced to accept foreign workers in response to this situation.

1-2 Information for People Working with Specified Skilled Worker Status

The Immigration Services Agency compiles and publishes the number of people working under Specified Skilled Worker status once every half year (once every three months until 2022). According to that data, the population ratios by country and age group are as follows.

As of the end of June 2024, 2,585 people work in the shipbuilding and ship machinery industry under Specified Skilled Worker status. By region, most workers are from Asia, with Vietnam, the Philippines, Indonesia, and Myanmar being the top countries of origin.

Although the Specified Skilled Worker system began in 2019, the number of people working in the shipbuilding and ship machinery industry under this status has increased by about 2.5 times over the past three years, and the number of accepted workers is expected to continue expanding.

1-3 Differences Between Technical Intern Training and Specified Skilled Worker

There are two systems for accepting foreign workers: the Technical Intern Training Program and the Specified Skilled Worker System, but their purposes and characteristics are very different.

The Technical Intern Training Program aims to help young people from developing countries acquire Japanese technical skills and contribute to the development of their home countries after returning. Its main purpose is skill acquisition, and it is positioned as training rather than labor. Therefore, job changes are not allowed, and the maximum period is five years.

On the other hand, the Specified Skilled Worker System was established to help address Japan's labor shortage. There are Specified Skilled Worker (i) and (ii), and the system accepts foreign workers as job-ready workers. Job changes are possible, and under Specified Skilled Worker (ii), bringing family members and obtaining permanent residency may also be possible. Tests to prove skills and Japanese language ability are required, and people with practical experience may have an advantage.

In addition, foreign nationals who have completed technical intern training can transition to the Specified Skilled Worker System. Experience gained through technical intern training is recognized, and some tests for Specified Skilled Worker (i) may be exempted, making the transition relatively smooth. This allows them to continue working in Japan for a longer period as Specified Skilled Workers after completing technical intern training, expanding opportunities for job changes and career advancement.
