Previous CEO Hisao Tanaka and several other board members stepped down amid the scandal, and the company has promised to improve its governance by bringing in more outside directors.
New Chief Executive Masashi Muromachi said on Monday he was also considering an overhaul of its weaker operations. Analysts expect big cost cuts in weaker operations such as PCs and TVs.
"I'm currently considering various options for structural reforms that will be both drastic and without limitations," he told a news conference, adding that he aimed to announce some details in late October or early November.
He also said he did not plan to stay in his CEO role for too long, and that he wanted to hand over to a successor after restructuring and preparing the company for future growth.

The quarterly results showed revenue fell 5 percent from a year earlier to 1.35 trillion yen. Net PC sales fell 31 percent to 116.8 billion yen while TV sales roughly halved to 21.8 billion yen, it said.
Toshiba's nuclear business also struggled, and its energy and infrastructure unit recorded an operating loss of 10.7 billion yen compared with a profit of 10 billion a year earlier.
With Monday's announcement, Toshiba has finally caught up with its regular financial disclosures. It had twice postponed its full-year results due to the accounting investigation, raising fears the company could be delisted from the Tokyo bourse.
The bourse said on Monday it placed Toshiba shares on a watch list and fined the company 91.2 million yen for betraying investors' trust.
Financial regulators are widely expected to impose a separate and more serious fine.
Toshiba shares fell 2 percent on Monday in Tokyo, ahead of the announcement of the quarterly results. They have tumbled around 38 percent since the company first disclosed the accounting problems in early April.
