Materiality

Materiality <Environment>
Addressing Climate Change At our sites, including headquarters and factories, we are working to reduce greenhouse gas emissions by introducing renewable energy sources such as solar power generation. In each department, we promote GHG reduction activities by establishing specific climate change countermeasure initiatives and KPIs, and monitoring and managing their performance against these targets.
Development of Environmentally Friendly Products Leveraging the technologies and expertise we have cultivated over the years, we are committed to developing environmentally friendly products from a variety of perspectives to help realize a sustainable society.
Materiality <Social>
Promotion of Diversity, Equity & Inclusion (DE&I) Respecting the human rights and dignity of each individual, we aim to foster a corporate culture in which diverse human resources can thrive with peace of mind in a fair environment.
Human Resource Development We aim to develop human resources who anticipate the needs of society and take on new opportunities boldly, with energy and a sense of purpose.
Improving Employee Well-being and Promoting Occupational Safety Giving due consideration to the physical and mental health and safety of our employees, we build a workplace environment where each employee can demonstrate their abilities and feel the joy of growth.
Contribution to Local Communities In addition to manufacturing that contributes to society, we support a variety of local activities, including regional environmental conservation, resource circulation, and cultural contributions.
Materiality <Governance>
[From the Perspective of Social Contribution and Profit Generation]
Improving Management Transparency and Soundness To build a management system that can respond quickly to changes in the business environment, we will strengthen corporate governance by utilizing outside directors with diverse skills and experience, aiming for sustainable improvement in corporate value.
Promotion of Sustainability Management We will build a sustainability management system optimal for our company, based on the expectations for sustainability activities required by society.
