We help employees to balance career and child-rearing, and corporate life and family life.

We are addressing “renovation of workplace culture.”

『Work-Family Balance declaration 』
For our efforts to adopt WLB into our employees’ life.

 Nowadays, we are facing flood of problems including child-care, nursing care and labor power problems due to decreasing birthrate and aging population, increasing number of suicides caused by heavy work load, family breakdown and increasing number of employees with mental health disorder due to problems in work environment. In this society with those problems in background, we’ve recently started tackling with mental health problems, sexual harassment, power harassment and heavy work load in order to provide working environment where employees work safely and comfortably.  We consider that by our efforts to achieve the work-life balance, each employee will feel fulfillment in his/her whole life including the life at work, which serves as important driving forces in creating energy and heightened sense of value, eventually leading to corporate’s continued growth and development. Based our belief, starting from 2006 we conducted a survey to know the status of employees and tried hard to keep employees informed about our child-care and nursing care help system and encouraged them to make best use of the benefit and also encourage them take paid holidays through in-house lectures. We know it is not so easy for our employees to achieve work-life balance as long as they are working in a contractor company.  However, it is our mission to change the current old-fashioned corporate culture as seen in the era of high economic growth gradually to such a new workplace as to provide workers with work-life balance.
