¥26,475 million and ¥28,567 million at December 31, 2010 and 2009, respectively. Investments with
an aggregate cost of ¥24,053 million were not evaluated for impairment because (a) Canon did not

of the investments and (b) Canon did not identify any events or changes in circumstances that might
have had significant adverse effects on the fair value of those investments.

<!-- Begin Block Tagged Notefalsefalsefalsefalsefalse | Otherus-types:textBlockItemTypestringThis item represents the entire disclosure related to Investments in Certain Debt and Equity Securities (and certain other trading assets) which include all debt and equity securities (other than those equity securities accounted for under the equity or cost methods of accounting) with readily determinable fair values. Other trading assets include assets that are carried on the balance sheet at fair value and held for trading purposes. A debt security represents a creditor relationship with an enterprise that is in the form of a security. Debt securities include, among other items, US Treasury securities, US government securities, municipal securities, corporate bonds, convertible debt, commercial paper, and all securitized debt instruments. An equity security represents an ownership interest in an enterprise or the right to acquire or dispose of an ownership interest in an enterprise at fixed or determinable prices. Equity securities include, among other things, common stock, certain preferred stock, warrant rights, call options, and put options, but do not include convertible debt. An entity may opt to provide the reader with additional narrative text to better understand the nature of investments in debt and equity securities (and other trading assets).Reference 1: http://www.xbrl.org/2003/role/presentationRef
