                       NOTICE REGARDING CHANGE IN AUDITORS



     Notice is hereby given that the following change (resignation) in auditors
of ADVANTEST CORPORATION (the "Company") was approved by the Company's Board of
Directors on July 28, 2004, pursuant to Paragraph 1 of Article 193-2 of the
Securities and Exchange Law.


1. Reason for change
     On July 25, 2003, KPMG AZSA & Co. was appointed auditor to jointly audit
     the Company's consolidated financial statements with Ernst & Young
     ShinNihon. However, as the use of one auditor enhances efficiency, the
     Company decided to unify the auditors and delegate auditing
     responsibilities only to Ernst & Young ShinNihon.

2. Name of resigning auditor
     Name:                      KPMG AZSA & Co.
     Location of Head Office:   AZSA Center Building, 1-2 Tsukudo-cho,
                                Shinjuku-ku, Tokyo

3. Prospects
     Ernst & Young ShinNihon will continue to carry out the Company's audit
     pursuant to Paragraph 1 of Article 193-2 of the Securities and Exchange
     Law.
