Aiming for Diverse Human Resources

Measures towards
employment for persons withdisabilities ~ Establishing
YOKOWO FUTURE-ORIENTEDSUPPORT
Koichi Fukagawa
Director, Senior Managing Executive Officer
YOKOWO FUTURE-ORIENTED SUPPORT CO., LTD.
Representative Director

Year by year, it is becoming increasingly difficult to hire high-caliber staff, and so
we are promoting the hiring and training of a diverse range of human resources
under our basic policy of promoting diversity and inclusion.
One of our efforts to utilize diverse human resources is to promote theemployment of people with disabilities. When people with disabilities can leverage
their specific characteristics and strengths to take on certain tasks within aworkplace, this increases the productivity of the workplace as a whole, and leads
to a sense of fulfillment and job motivation for these people. We also feel thathaving our employees work alongside people with disabilities will drive home thefact that we are serious about promoting diversity and inclusion.
Many of our employees with disabilities have left the company mid-career, andas a result we have failed to meet the legally mandated employment rate. Upon
analysis of this low retention rate, we found the main reasons to be insufficienttraining in each workplace to accommodate people with disabilities, and a lack ofsupport systems in terms of business and lifestyle for these employees.
Accordingly, we determined that it was necessary to establish a subsidiary
dedicated to the employment of people with disabilities. The subsidiary would
cover education on the characteristics of people with disabilities and the creationof opportunities in which they can play an active role, through to assigning publichealth nurses and mental health and welfare professionals to provide healthand lifestyle support. Accordingly, we established YOKOWO FUTURE-ORIENTEDSUPPORT CO., LTD. in April 2022.
At present, the work undertaken by people with disabilities through YOKOWO
FUTURE-ORIENTED SUPPORT includes cleaning and disinfecting the factory,
parts inspections and packaging at production sites, and data entry in the design
department. Management and key personnel at YOKOWO FUTURE-ORIENTEDSUPPORT are veteran employees with a deep knowledge of Yokowo operations,
including design and manufacturing. Therefore, the creation of work for people
with disabilities is proceeding smoothly.
In the future, the company plans to expand its cleaning and disinfecting
business beyond the Yokowo Group's own operations to include cleaning,
disinfecting and planting business at local community centers, gymnasiums,
and other sports facilities. Through such measures, it aims to become a special
subsidiary well-loved by local communities, and to further improve job satisfaction
and motivation of people with disabilities.
