Governance
The Board of Directors is composed of 9 directors (of whom 4 are outside directors), and since 2016 the company has introduced an executive officer system to separate decision-making from business execution. It has established a Nomination and Compensation Advisory Committee, and has built a structure in which eight specialized committees, including the Sustainability Promotion Committee, report regularly to the Board of Directors.
Risk Management
The Sustainability Promotion Liaison Council is responsible for risk management based on materiality and KPIs, while the CO2 Reduction and Effective Utilization Promotion Committee deliberates on climate change risk at least twice a year. Human capital risks (recruitment, talent development, and organization) are also managed through KPIs, and a system has been established whereby the deliberations of each committee are submitted to and approved by the Board of Directors.
Shareholder Returns
Under the medium-term management plan (through FY2028 (ending March 2028)), the company targets a total shareholder return ratio of 50%. Dividends are paid with a floor of ¥100 per share annually, and if the payout ratio falls below 50%, share buybacks are used to supplement returns. The annual dividend for FY2026 (ending March 2026) is ¥100 per share (interim ¥50 + year-end ¥50), with total dividends of ¥31,188 million and a payout ratio of 75.5%. The company plans ¥500 million in share buybacks over three years, of which ¥25.0 billion has already been executed between August 2025 and March 2026.
Dividend Policy
The basic policy is to pay continuous and stable dividends, with a floor of ¥100 per share annually. If the payout ratio falls below 50%, the company will repurchase shares to maintain a total shareholder return ratio of 50%. The annual dividend for FY2026 (ending March 2026) is ¥100 per share (interim ¥50 + year-end ¥50), with total dividends of ¥31,188 million and a payout ratio of 75.5%. For FY2027 (ending March 2027), the same annual amount of ¥100 (interim ¥50 + year-end ¥50) is planned.
ESG
With respect to climate change response, the company has set targets of a 30% reduction in GHG emissions by FY2030 (versus FY2018) and carbon neutrality by 2050, and is implementing measures such as the construction of a biomass power plant (investment of approximately ¥40.0 billion, with CO2 reduction of approximately 500,000 tons). In terms of human capital, the company has prioritized the development of autonomous human resources and the promotion of diversity, and has achieved KPIs such as a 100% male childcare leave utilization rate and an 85% paid leave utilization rate in FY2025.
