▲ Nagai Giken staff with technical internship experience actively working on-site
Nagai Giken Thailand handles production equipment, labor-saving equipment, jigs, and parts under an integrated system covering everything from design to manufacturing. One of the secrets behind the company’s ability to deliver Japanese quality, one of its key strengths, is the presence of highly capable local on-site staff who fully understand both quality standards and the Japanese way of thinking.
They have experience as technical interns at manufacturing sites in Japan and can understand almost everything in Japanese, from on-site communication to design drawings and work instructions. Approximately 90% of Nagai Giken Thailand’s local staff are former technical interns, enabling them to respond quickly to the detailed requirements of Japanese customers.
This time, we introduce “S.I. PLACEMENT CO., LTD.” (S.I. Placement), the staffing company Nagai Giken Thailand uses to recruit personnel with technical internship experience.
■ S.I PLACEMENT: Human Resources Consulting by a Manufacturer, for Manufacturers, with Strength in Recruiting Thai Personnel with Technical Internship Experience

S.I. Placement (hereinafter referred to as SIP) belongs to the SATAKE Group, whose parent company is Satake Seisakusho Co., Ltd., a company mainly engaged in metal processing in Japan. Its parent company, Satake Seisakusho, established a Foreign Human Resources Department in 2019. Using SNS, websites, and other channels, it recruited foreign workers, primarily Thai nationals, and built up an extensive recruitment track record. Even today, 55% of the employees at Satake Seisakusho’s Yamagata Factory are Thai. Originally, the company gathered people with technical internship experience for its own recruitment purposes, but it later applied its recruitment know-how to establish a staffing business called “Factory Lab.”

SIP provides personnel introductions and consulting services involving people with work experience in Japan for manufacturing companies in Japan and Japanese manufacturing companies in Thailand. Focusing mainly on placing Thai and Indonesian personnel, it has already conducted business with more than 100 companies.
■ Thai “U-Turn Personnel” Who Have Acquired Language and On-Site Skills in Japan
SIP mainly introduces personnel to Japanese companies who are either “currently working in Japan and hope to return to Thailand for employment in the future” or “have already returned to Thailand from Japan and are seeking employment with Japanese companies in Thailand.”
Most candidates have work experience in Japan as technical interns and have learned Japanese technology, culture, and working methods. During their three to five years of training, they also acquire Japanese-language proficiency at levels ranging from N4 to N2.
Its greatest feature is the ability to introduce work-ready personnel who match a company’s requirements from an extensive database of more than 10,000 people.


“There is probably no other staffing company with a network of Thai personnel who have technical internship experience at Japanese manufacturing sites. Another strength is that, because we are also involved in manufacturing ourselves, we have a deep understanding of the type of personnel Japanese manufacturing companies are looking for. And because we have bases in both Japan and Thailand, we are able to provide support that stays close to Thai technical interns (job seekers). I think this makes it easier for talented and serious people to gather around us.” (Mr. Chijiiwa of SIP)
President Nagai of Nagai Giken Thailand places tremendous trust in SIP, saying that being able to recruit capable personnel through SIP has led to improvements in quality.
