Tokio Marine Holdings, Inc. (the "Company") announced today that it has revised its forecasts of business results under Japanese GAAP for the fiscal year ended March 31, 2009 (April 1, 2008 to March 31, 2009, "FY2008") previously announced on February 13, 2009. The revisions are detailed below.

1. Revised Forecasts of Consolidated Business Results of the Company for FY2008

("Tokio Marine & Nichido"), a consolidated subsidiary of the Company, as detailed in "(Reference)" below. Tokio Marine & Nichido revised its original business forecasts primarily because its incurred losses relating to large claims are expected to be less than previously forecasted.
