Naito Museum of Pharmaceutical Science and Industry: Cultivated and managed approximately 700 species of medicinal and useful plants, including 40 endangered species. Kashima Plant: Management of plantations and promotion of tree planting EA Pharma Co., Ltd. Fukushima Plant: Preserved the planted trees on the premises, including Somei-Yoshino and weeping cherry trees. Vizag Site (India): Continued the planting program from fiscal 2020, and a total of approximately 11,000 trees have been planted so far. Bogor Plant (Indonesia): Preserved nationally protected orchids.
Resource conservation	Promotion of awareness-raising activities and education to encourage green purchasing Reduction of copy paper usage	Eisai Co., Ltd.	Implemented awareness-raising and education activities whenever appropriate. The green purchasing ratio: 23.1% (8.1% decrease from fiscal 2023) Utilized electronic materials and web meetings. Used 17,918,991 sheets of copy paper (50.0% increase from fiscal 2023).
Conservation of the local environment	Compliance with environmental-related laws (noise, vibrations, offensive odors, soil contamination) Involvement with local community Zero complaints made by neighbouring residents	Japan	Regularly measured levels of noise, vibrations and offensive odors to confirm compliance. Held regular cleanup activities of areas around each operation site and affiliated company as well as within industrial parks. No complaints were reported.
