Employees

For the Otsuka group, employees are the foundation for driving innovation and executing business strategy, as well as a source of value creation. Feedback gathered through employee engagement surveys and dialogue with management is used to enhance talent development initiatives, advance DE&I, and improve efforts to create safe and healthy workplaces. Through these initiatives, the group strives to create a work environment where diverse talent can fully realize their potential. Feedback received through the whistleblowing system is also reflected in improvements to organizational management, helping to foster an open corporate culture.

Employee-driven environmental initiatives: The Otsuka Group Environmental Awards

The Otsuka Group Environmental Awards have been held since 2018 to recognize outstanding environmental initiatives undertaken by group companies in Japan and overseas for their originality and exemplary nature. Many of the initiatives submitted for the awards are driven by employees across different regions and workplaces who identify challenges in their day-to-day operations, test hypotheses, and make improvements that help reduce environmental impact. By recognizing outstanding initiatives and sharing them across the group, the awards help further advance environmental activities while encouraging greater employee participation.
