Medium-Term Business Plan “EWAY Future & Beyond”
Under our current medium-term business plan, “EWAY Future & Beyond,” we have expanded the scope of the people whose health care needs we seek to address beyond the medical domain to include the people in the daily living domain. Building on our foundation in neurology, particularly dementia, and oncology, we aim to evolve into an hhceco company (hhc concept + ecosystem). By creating science- and data-driven solutions and building ecosystems in collaboration with other industries and organizations, we seek to empower people to “realize their fullest life.”
In FY2026, we formulated a three-year plan covering FY2026–FY2028 as a step toward realizing our long-term vision of “maximizing health value for each and every one of ‘The People.’” The plan will be updated annually on a rolling basis to reflect changes in the external environment and support effective execution.
Innovation Focus Areas: “Drug Discovery R&D” and “Non-drug Discovery R&D”
Eisai promotes innovation through both “Drug Discovery R&D,” which uses science to create innovative medicines, and “Non-drug Discovery R&D,” which develops solutions beyond pharmaceuticals to help alleviate people’s anxieties and concerns.
Corporate Concept
We give first thought to patients and the people in the daily living domain, and increase the benefits that healthcare provides to them as well as meet their diverse healthcare needs worldwide.
Eisai's corporate philosophy reflects our commitment to business activities aiming to increase the benefits to patients and the people in the daily living domain, who we clearly recognize as the key players in healthcare. This corporate concept is summarized by the term
“human health care (hhc)”.
All employees are recommended to spend 1% of
their working hours with patients
