TOKYO (Reuters) - Bain Capital is planning to launch a tender offer for Japanese software firm Fuji Soft in early November rather than late October as originally planned but still awaits company approval, the private equity firm said on Friday.

Bain has been locked in a $4 billion takeover battle for the firm with rival KKR, a deal that underscores Japan's resurgence in global dealmaking, now as a target for buyouts.

Bain said it had held Q&A sessions with Fuji Soft on Oct. 24 and 29 and would continue discussions in order to obtain the affirmative opinion from the company that it has set as a condition for launching its offer.

This week Bain said in a statement it would be willing to accept a partial tender offer and that it would be willing to work with other shareholders to raise corporate value in the company.
