Rhea-AI Summary

Advantest Corporation, a Japanese company, and JPMorgan Chase Bank, N.A. as depositary are updating and expanding their American Depositary Share (ADS) program through a Form F-6 registration statement. The registration covers 500,000,000 American Depositary Shares, each ADS representing one share of Advantest common stock, with a proposed maximum aggregate offering price of $25,000,000 and an associated SEC registration fee of $3,452.50.

This registration functions as Post-Effective Amendment No. 3 to an existing Form F-6 (No. 333-13886) under Rule 429, so the same prospectus also relates to ADS previously registered under that earlier statement. The ADS terms are governed by a Second Amended and Restated Deposit Agreement, under which the ADR form serves as the prospectus and describes voting procedures, dividend collection and distribution, fees, transfer restrictions, and limitations of liability. Advantest states that it publishes required English-language information on its website to maintain its Rule 12g3-2(b) exemption from Exchange Act registration.
