Who We Are

Our Global Mission

Our human health care mission, the desire to contribute to patients, is our corporate philosophy and the core of our business. Established in 1992, the hhc philosophy is a common value among all employees worldwide. Spending time with patients and understanding their true needs has become the source of Eisai’s innovation.

With the introduction of EWAY 2025, our medium-term business plan, we updated our patient socialization program to include internal innovation training and enhance our commitment.

Also in EWAY 2025, Eisai selected two therapeutic areas of focus: neurology and oncology. In these areas, we believe it is important to find “Ricchi” – a Japanese term that means finding a place “where real patient needs are still unmet; where Eisai can become a frontrunner.”
