■ Background
As the care and welfare sector continues to face a chronic labor shortage, the acceptance of foreign professionals is expanding. However, in a field that simultaneously demands language acquisition, job proficiency, and qualification attainment, cases leading to long-term retention and national certification are still not common.
Social Welfare Corporation Shiraoi Kōyūkai, which provides services for people with disabilities in Shiraoi, Hokkaido, began accepting foreign professionals against a backdrop of population decline and recruitment difficulties, having hired a total of nine individuals to date.
■ Initiatives and Process to Qualification
Even before coming to Japan, Mr. Rendy had the goal of 'obtaining the Certified Care Worker qualification to work in Japan for the long term.' After joining the corporation, he continued to study Japanese and prepare for the exam in parallel with his work duties.
Shiraoi Kōyūkai, in what was a first-time endeavor for them, gradually established a site-based support system through trial and error. This included sharing past exam questions, conducting mock exams, and securing study time during work breaks.
As a result, Mr. Rendy successfully passed the national Certified Care Worker exam in his fourth year of employment.
■ Comments
Mr. Shinpei Ikkoma, General Facility Manager, Social Welfare Corporation Shiraoi Kōyūkai
'I think it was extremely difficult to juggle work, Japanese language studies, and qualification studies all at the same time. Honestly, I didn't expect him to pass in four years. Based on this success, we will now establish a system for planned study from the first year.'
Mr. Rendy
'I was determined to become a Certified Care Worker from the very beginning. Balancing work and study was tough, but it was a great help that the company created time for me to study.'
■ The Value of This Case from NINAITE's Perspective
In the acceptance of foreign professionals, it is not uncommon for retention and development to be cut short due to post-hiring mismatches or communication challenges. This is precisely why building relationships through daily on-site interactions is crucial.
In this case, the host company and the individual diligently continued this cumulative process, achieving both job proficiency and qualification. This daily accumulation is the essence of what led to this successful qualification. What is particularly noteworthy is that both the foreign professional and the host company continued to build their relationship while tackling the challenge of balancing on-site work and learning.
Furthermore, with the acquisition of the Certified Care Worker qualification, Mr. Rendy has become a full-time employee and is now expected to serve as a role model for junior talent.
As a company responsible for building the foundation upon which corporations and foreign professionals can cultivate their relationships, NINAITE Inc. will continue to support the realization of a welcoming environment where both parties can work together for the long term.
