Ryusuke Ishii is a Japanese social insurance and labor consultant who supports small and medium-sized businesses in human resources and workplace management. After spending fifteen years in the financial sector, working in asset management, corporate lending, and sales, he changed careers to become a labor and social security attorney. He advises both employers and employees on labor disputes, recruitment, retention, and the improvement of workplace practices. In “How to Make a Company Profitable by Shortening the Standard Workday by One Hour” (『「1時間」定時を短くしても、儲かる会社になる方法』), he argues that reducing working hours is not enough; companies must redesign work and make better use of limited talent in response to population decline and labor shortages. His approach connects labor management with productivity and the long-term stability of the business.
