In a commendable stride towards supporting working parents, One Career, a Tokyo-based company specializing in career data platforms, has recently received the prestigious Kurumin certification from the Japanese Ministry of Health. The company, which operates with the mission to create diverse career opportunities for individuals, emphasizes the importance of creating a workplace that enables employees to balance work and parenting effectively.
What is Kurumin Certification?
The Kurumin certification is a designation awarded to companies that actively promote the support of employees raising children, as per the Act on Advancement of Measures to Support Raising Next-Generation Children. Companies involved must draft and implement a concrete action plan that meets specific criteria established by the Ministry of Health. This initiative aims to acknowledge organizations that are evolving to better support their workforce, especially in the area of childcare.
One Career's Commitment to Work-Childcare Balance
At One Career, the mission, "Creating careers for as many people as there are," drives not only its business model but also its internal culture. The company recognizes that fostering a supportive environment for employees at different stages in life is crucial for long-term success. To embody this mission, One Career has implemented flexible work systems, including flextime and remote working options, ensuring that all employees can choose work arrangements that accommodate their changing life circumstances.
As a direct outcome of these initiatives, One Career boasts an impressive childcare leave uptake rate, achieving 100% for female employees and 75% for male employees as of December 2025. These numbers reflect both the effectiveness of their system and a significant step toward retaining skilled human resources within the organization.
Future Aspirations
With the newly acquired Kurumin certification, One Career is further motivated to enhance its work environment, allowing employees to maximize their potential regardless of life changes. The company aims to foster an atmosphere where working parents can confidently continue to grow, ensuring that the vision of creating diverse career paths remains at the forefront. As they continue to accelerate their business growth, One Career is committed to maintaining supportive policies that champion work-life balance.
