TOKYO -U.S. buyout fund Bain Capital has made a counter-offer to buy Japanese software developer Fuji Soft for about 600 billion yen ($4.1 billion), or around 5% higher than private equity firm KKR's bid, the Nikkei newspaper reported on Tuesday.

Bain is believed to have proposed a price of around 9,200 to 9,300 yen for each Fuji Soft share, against KKR's tender offer last month of 8,800 yen a share, the Nikkei said. The stock closed at 8,970 yen on Tuesday.
