The Concept of Sustainability
Basic Concept
Our predecessor, Postal Life Insurance Service, was launched with the social mission of "protecting the means of fundamental livelihood of the public through simple procedures."
We have been privatized, but our mission to support people's lives through insurance has not changed.
Under our management philosophy "Be a trustworthy partner for people, always being close at hand and endeavoring to protect their well-being." we have set a "Sustainability Policy" to help resolve social issues and to work to achieve SDGs by fulfilling our social mission (purpose) and meeting social needs in an age of the 100-year life.
We are also working to resolve issues related to sustainability through our business activities.
Sustainability Promotion System
Japan Post Insurance established the Sustainability Promotion Office in the Public Relations Department in April 2021, and the Sustainability Promotion Department in April 2024 to strengthen the promotion framework.
The Sustainability Committee, chaired by the Executive Officer in charge of the Sustainability Promotion Department, discusses sustainability strategies, formulates and reports on the progress of sustainability implementation plans, and reports the status of deliberations and discussions at the Sustainability Committee to the Executive Committee in a timely manner, with important matters being discussed and decided upon at the Executive Committee before being reported to the Board of Directors.
Sustainability Implementation Plan
To fulfill our social mission and address sustainability-related issues, Japan Post Insurance identified five materiality items (important issues), which were reviewed in March 2024 in light of changes in the external environment. In order to promote initiatives in line with materiality, we have formulated a Sustainability Implementation Plan related to each materiality, and we confirm and evaluate the status of implementation. The progress is reported as appropriate to the Sustainability Committee, Executive Committee, and Board of Directors.
In the FY2025 Sustainability Implementation Plan, we have set approximately 40 specific initiatives and corresponding KPIs.
Internal Penetration Measures
Conducting Exchange Opinions
We provide opportunities for employees to exchange opinions in small groups on the theme of sustainability, so that each employee can make sustainability their own business and take autonomous action. The FY2024 event focused on themes such as the necessity of sustainability in the life insurance industry.
Sustainability Training
To deepen understanding of sustainability and SDGs, we regularly hold sustainability training for executives with external lecturers, and in the fiscal year ended March 31, 2025, we held two sessions on the relationship between corporate value and ESG, as well as on well-being.
Contributing to Society through Life Insurance Business
Through the life insurance business, we protect customers' lives by paying insurance claims to customers throughout Japan.
Customer Base
We have not only an extremely large customer base of approximately 16.92 million people, but also connections with customers of the Japan Post Group nationwide, allowing us to provide many customers with peace of mind through insurance.
