At Kimura Soap, one of the core organizational philosophies is that “since we spend most of our waking hours at work, it should be fun and engaging — otherwise it’s a waste.” Breaking away from rigid corporate norms, the company has eliminated needless formalities (like traditional approval paperwork and rote reporting) so that employees can work freely and comfortably, without excess bureaucracy. For decades, Kimura Soap has operated under the idea that you can’t do good work without a happy home life, actively reducing overtime; today there is virtually no overtime at the company. Leaving the office on time is the norm, and everyone is encouraged to cherish their family and personal time. A culture of trust and deep appreciation for each employee is strongly rooted in the company — it is part of what makes Kimura Soap proud of its team and how it works. This commitment to caring for employees aligns perfectly with the B Corp values of supporting workers and all stakeholders. As a Certified B Corporation, Kimura Soap will continue to foster a workplace where staff can thrive and be themselves, using business as a force for good in the community and beyond.
