Otsuka Holdings Launches First Wind Power Procurement Initiative
2026/01/13
Partnership with Shikoku Electric Power to Cut CO₂ Emissions by 1,000 Tons Annually
Otsuka Holdings Co., Ltd., the parent company of Otsuka Pharmaceutical, has introduced wind-generated electricity for the first time across its group operations. The company will receive power from wind farms owned and managed by Shikoku Electric Power, with the initiative expected to reduce carbon dioxide (CO₂) emissions by approximately 1,000 tons per year.
The electricity will be supplied from Shikoku Electric Power’s Otoyo Wind Power Plant located in Otoyo Town, Kochi Prefecture, where three wind turbines generate renewable energy. The two companies have signed a long-term agreement under which the entirety of the generated power will be used by the Otsuka Holdings group. The electricity will be categorized as “self-generated renewable energy,” created through collaboration with power producers rather than through Otsuka’s own facilities alone.
Through this initiative, the proportion of self-generated renewable energy within the Otsuka Holdings group is expected to rise to approximately 5 percent. While the company has previously promoted the installation of solar power systems, fluctuations in output due to weather conditions have posed challenges. By adding wind power to its energy mix, Otsuka aims to secure a more stable renewable energy supply and diversify its power sources.
Otsuka Holdings has set environmental targets aligned with its 2050 “Net Zero” vision, including raising the share of self-generated renewable energy to 20 percent and reducing CO₂ emissions by 50 percent from 2017 levels by 2028. Looking ahead, the group is also considering the use of hydropower and plans to accelerate its decarbonization efforts through continued collaboration with partner companies.
