And while two activist funds fell short in their bid to add a total of 5 nominees to the board, one nominee - Yoichiro Imai, the co-founder of activist fund and Toshiba's top shareholder Effissimo Capital Management - gained substantial backing with 43% of the vote.

Both results, disclosed on Tuesday, indicate that pressure from activist funds on the beleaguered Japanese industrial conglomerate is likely to remain for some time.

Singapore-based Effissimo, which owns a 9.9% stake, had sought additional directors, citing fictitious transactions Toshiba disclosed this year as evidence that its corporate governance has not made significant progress since a major accounting scandal in 2015.

Proxy advisers Institutional Shareholder Services Inc and Glass, Lewis & Co had sided with Toshiba, arguing that the current management team is relatively new and diverse.

Toshiba has been under pressure from activist funds since it sold 600 billion yen ($5.6 billion) of stock to dozens of foreign hedge funds during a crisis stemming from the bankruptcy of its U.S. nuclear power unit in 2017.

Effissimo and other activist funds hold about 30% of Toshiba's voting rights. Foreign shareholders in total account for about 60%. Toshiba added seven new independent directors last year at the urging of U.S. hedge fund King Street Capital.
