Eisai Taiwan Inc. (Eisai Taiwan) is a pharmaceutical company wholly owned by Eisai Co., Ltd. (Eisai), a Japanese multinational pharmaceutical company headquartered in Tokyo, Japan.

Eisai entered the Taiwan market in 1961 to establish its first overseas business and set up its sales subsidiary in Taipei in 1967. The group has since continued to develop and expand business in Taiwan.

In the 1960s, we focused solely on the marketing f products imported from Eisai in Japan. In the 1970s and 1980s, our Tainan Plant acquired good manufacturing practice (GMP) certification and began local production. 

In 1995, we officially established Eisai Taiwan Inc.

Currently, we have 90 employees (as of March, 2014). We promote and market 21 products (as of January 31, 2013), with our main focus being on central nervous system (CNS), gastrointestinal (GI) and over-the-counter (OTC) products.
