Teijin Again Selected For Dow Jones Sustainability World Index

TOKYO, Japan — September 14, 2010 — Teijin Limited announced today that it has been named,
following last year, to the Dow Jones Sustainability World Index (DJSI World), a global indicator
for Social Responsible Investment (SRI).

The new DJSI World list will be made effective on September 20, 2010. Of the 318 companies
selected this year, 36 are Japanese. Among the nine companies from the chemical sector, Teijin is
the only one from Japan.

The DJSI World, which was jointly developed by Dow Jones and Swiss-based SAM Group in 1999,
is the most important sustainability index and represents the top 10 percent of the largest 2,500
companies in each industry included in the Dow Jones Global Index. The index assesses the economic,
environmental and social performance of those companies every year to identify those that exemplify
leadership in sustainability.

Teijin has also been named to Dow Jones Sustainability Asia Pacific Index, also following
last year, and is being included in other international SRI indexes such as the FTSE4Good Index and
the Ethibel Sustainability Index.

Giichi Morita, CSRO (Chief Social Responsibility Officer) and Senior Executive Officer of
