MESSAGE
Message from our representative director
I am a third-generation Brazilian of Japanese descent. I came to Japan at the age of 20 and gained experience in manufacturing plants. I worked in staffing and outsourcing and, at one point, managed more than 2,000 people. I decided to start my own business to give back to the country that had welcomed me. Despite the pandemic, I established Jinko in November 2020. With the discipline I learned in Japanese manufacturing, we overcame difficulties, achieved three times our first-year target and doubled our growth in the second year. I will continue to serve everyone with sincerity. I am committed to moving forward with passion and a sense of purpose, helping build a brighter future for Japan.

Bringing talented people closer
Developing talented personnel.
We support efficient, strategic management through on-site manufacturing outsourcing and temporary staffing. Securing and effectively using human resources is essential to manufacturing. Companies must maintain sufficient skilled staff while improving working conditions to address persistent labour shortages. Through outsourcing, we take responsibility for part or all of a production process or line according to the client's needs, helping improve management efficiency. We can also supply experienced workers in the fields and numbers required. With a structured training system, we act as a partner supporting businesses through their people.

STAFFING
Temporary staffing services
In temporary staffing, workers employed by a staffing company are assigned to work at a client company. Their employment contract is with the staffing company. The client directs their day-to-day work but does not enter into a direct employment contract with them. This service helps secure the people needed quickly and efficiently, with flexibility for unexpected absences and busy periods.

Do these challenges sound familiar?
Not enough people on the production floor.
Difficulties expanding lines or changing product models.
A need to respond to sudden production increases.
Difficulties retaining newly hired employees.
Concerns about whether current contracts comply with the latest rules.
The experience described on the website includes more than 20 years of recruiting Brazilians of Japanese descent. Our recruitment network and regional knowledge help us find people throughout Japan for different needs.

Our work does not end with placing staff. We revisit the workplace, identify and analyse underlying issues and work on improvements. Our aim is to meaningfully increase efficiency and productivity while fulfilling our mission and strengthening our relationships with clients.
OUTSOURCING
On-site manufacturing outsourcing
On-site outsourcing may be referred to as contract work or business-process contracting. As described on the website, it involves an agreement to complete a specified result by the contractual deadline, with payment for the work delivered.

Do these challenges sound familiar?
A need for an experienced contractor that manages its own workforce.
A need for a company that can adapt to your production methods.
A need for a contractor that follows applicable requirements.
Outsourcing can reduce costs associated with direct employment. We apply knowledge gained across different workplaces to help improve quality and resolve issues. Outsourcing part of manufacturing allows your own employees to focus on core business activities. We support clients with flexibility and sincerity.
Outsourcing can reduce costs and management workload.
When specialist knowledge is missing internally, new recruitment and training can require additional investment. Engaging a specialist contractor can reduce that effort and cost. Since the contractor manages its own workers, outsourcing can also reduce the client's administrative workload.
