2. Overview of Corporate Name Change

(1) Reason for Change

As part of efforts to further realize its human health care corporate mission, Eisai Co., Ltd. (“Eisai”) inaugurated Eisai Japan in June 2010 as an organizational body tasked with the development and implementation of comprehensive strategies across its four Japan business segments comprising prescription pharmaceuticals, consumer healthcare products, diagnostics and generics. Against this backdrop, Eisai has decided to change the corporate name of its subsidiary Sanko Junyaku Co., Ltd. in order to clearly redefine the company's position as a wholly-owned diagnostic business arm of Eisai as it seeks to make further contributions to patients by strengthening collaborations within Eisai Japan so as to provide information and products that serve a broader range of medical needs from diagnosis through treatment.

(2) New Corporate Name

EIDIA Co., Ltd.

  • *
    The new corporate name was derived by combining the first two letters of Eisai Co., Ltd. with the first three letters of diagnosis.

(3) Scheduled Date of Name Change

April 1, 2011
