Hiromi KAWAMURA, Management Advisor
Zen. O Co., Ltd. Representative
Born in 1980 in Aichi Prefecture. After graduating from junior college, she went to Australia (Sydney) alone to study abroad and then to university, where she found employment as an accountant.
After returning to Japan in 2012, I joined an advertising agency (with approximately 300 employees) as a global finance specialist reporting directly to the CFO. For about seven years until 2018, I acted as a bridge between domestic and international operations, handling inter-departmental coordination such as accounting, human resources, general affairs, and IT (ERP), as well as managing and auditing overseas subsidiaries. I was also involved in negotiations and establishment of a Japan-U.S. joint venture that emphasized communication, gaining diverse experience.
I founded my company in 2019. I am convinced that exploring the material and spiritual essence of life, and living a life that utilizes one's talents and potential, leads to social contribution. I have developed unique know-how for talent development and aim to provide comprehensive proposals that go beyond my background as a former Australian Certified Public Accountant, including branding and image building.
