Carlyle Group will buy Japanese ball bearing maker Tsubaki Nakashima from Nomura Holdings for about $800m (£491.5m), the largest acquisition by a buyout firm in Japan in more than a year. Nomura said yesterday that its principal finance arm would sell a 95.56 per cent stake in Tsubaki Nakashima to Carlyle, estimating the company’s value at 66bn yen. Carlyle launched a 215.6bn yen Japan fund in 2006. A significant portion of the money has yet to be spent. Co-founder David Rubenstein also said Carlyle was looking at deals in the Middle East region, saying that the unrest has not yet had an impact on the private equity firm’s portfolio companies there.
