The Tokyo Stock Exchange has decided to seek a penalty of ¥91.2 million (approximately $600,000) from Nidec Corporation — the electronics components giant formerly known as Nihon Densan — following the discovery of fraudulent accounting practices at the company. The exchange cited damage to investor confidence as the basis for the fine, which represents the highest penalty level available under its rules. The case marks a significant regulatory response to one of Japan's more prominent recent corporate accounting scandals.
