What is Specified Skilled Worker (ii)? What is the difference with No. 1 and how to obtain it?

Hello, this is Kano from JAC (Japan Association for Construction Human Resources).

Many companies currently employing Specified Skilled Worker (i) nationals would like them to stay for as long as possible.

Since Specified Skills visa is a relatively new type of residence status, there are very few foreigners who have acquired Specified Skilled Worker (ii).

So, this time we will introduce the difference between Specified Skilled Worker (i) and Specified Skilled Worker (ii), and how to obtain Specified Skilled Worker (ii).

What is Specified Skilled Worker (ii)? Check out Specified Skills System

In order to solve the labor shortage at construction sites, the Immigration Control and Refugee Recognition Act was amended at the extraordinary session of the Diet in 2018, and a new status of residence called "Specified Skills" was created.

Specified Skills is a system that accepts foreigners not only at construction sites but also in specific industrial fields where labor shortages are serious.
Specified Skills accepts foreigners with the same treatment as Japan people.

In the past, those who had returned to their home countries after completing the training can now be called back and accepted directly.


Specified Skills has two types: Specified Skilled Worker (i) and Specified Skilled Worker (ii).

As of May 2024, the following 16 fields are available for Specified Skilled Worker (i).

  • nursing care
  • Building Cleaning
  • Industrial product manufacturing industry (formerly: Basic materials, industrial machinery, and electrical, electronic, and information-related manufacturing industry)
  • Automobile Maintenance
  • Aviation
  • stay
  • Agriculture
  • Fisheries
  • Food and beverage manufacturing
  • Foodservice
  • construction
  • Shipbuilding and Marine Industry
  • Automobile transport industry
  • Railway
  • forestry
  • Timber Industry

Of these, 11 fields are accepted by Specified Skilled Worker (ii), excluding nursing care, motor transportation, railways, forestry and timber industries.

Previously, Specified Skilled Worker (ii) only covered welding segments in the construction and shipbuilding and marine industries.
However, the scope of the Cabinet decision in 2023 has been expanded.
As of 2023, it is possible to accept Specified Skilled Worker (ii) in all industrial sectors except the nursing care field.

The four fields of "automobile transportation," "railway," "forestry," and "timber industry" will be newly added by the Cabinet decision in March 2024, and will be accepted from Specified Skilled Worker (i) first.
Therefore, as of May 2024, we will not be able to accept Specified Skilled Worker (ii).

In addition, according to the Cabinet decision in March 2024, new jobs have been added in the "industrial product manufacturing field," "shipbuilding and marine manufacturing industry," and "food and beverage manufacturing field," but as of May 2024, Specified Skilled Worker (ii) will not accept additional jobs in the "industrial product manufacturing field."

How is Specified Skilled Worker (ii) different from Specified Skilled Worker (i)?

What are the differences between Specified Skilled Worker (ii) and Specified Skilled Worker (i)?
We will compare the differences between Type 2 and Type 1 in terms of skill level, period of stay, and Japanese language proficiency.

  Specified Skilled Worker (ii) Specified Skilled Worker (i)
Qualification Overview For foreigners working in specific industrial fields who require skilled work For foreigners who are engaged in work requiring a considerable degree of knowledge or experience in a specific industrial field
Period of stay 3 years, renewable every year or every 6 months, no cap Renewal every year, six months or four months, up to a total of five years
Skill Level Check through exams etc. Confirmation by examination, etc. (Foreigners who have successfully completed Technical Intern Training (ii) are exempt from examination, etc.)
Japanese language proficiency level No need to check through tests etc. Japanese language proficiency necessary for daily life and work will be verified through tests, etc. (Foreigners who have successfully completed Technical Intern Training (ii) will be exempt from tests, etc.)
Bringing family members along Possible if certain conditions are met (spouse, children) Basically not acceptable
Support from host organizations or registered support organizations Not applicable subject

Specified Skilled Worker (ii) "Skilled skills" are required to have acquired skilled skills from a long period of practical experience, etc., and to be able to lead and supervise workers in the field.

On the other hand, the "skills that require a considerable degree of knowledge or experience" in Specified Skilled Worker (i) are the level at which a certain level of work can be performed without special training.
The transition to Specified Skilled Worker (i) is also possible with a successful completion of Technical Intern Training (ii).

The difference between Specified Skills and technical intern training is explained in detail here, so please refer to it as well.

Introducing the requirements and methods for obtaining Specified Skilled Worker (ii)

To obtain Specified Skilled Worker (ii), one must meet two requirements: 1) pass The Specified Skills (ii) Evaluation Exam or the Skill Test Level 1, and 2) gain a certain amount of practical experience as a supervisor or instructor.
The exam content and required work experience vary depending on the field.

For example, in the construction sector, “foreign nationals with skilled skills” can acquire Specified Skilled Worker (ii) by meeting the following two requirements.

  • A certain amount of practical experience as a team leader (practical experience as a team leader who supervises multiple construction technicians while working on a construction site and manages the process)
  • Pass The Specified Skills (ii) Evaluation Exam for Construction Industry (implemented by JAC), which is equivalent to the level of the Skills Test Level 1, or obtain the Skills Test Level 1

By the way, the condition for Specified Skilled Worker (i) is to pass a test to confirm Japanese ability along with the Specified Skills measurement test, but in the case of Specified Skilled Worker (ii), it is not necessary to take the Japanese test to obtain a status of residence.

The Specified Skills (ii) Evaluation Exam for Construction Industry (Implementing Entity: JAC) Please refer to the "The Specified Skills Evaluation Exam for Construction Industry page" for the implementation status.
