After years of passing up opportunities to invest in Japan, overseas investors should pay more attention to Japan equities, says the chief investment officer of Japan’s $1.1 trillion public pension reserve fund.

"I think the Japanese stock market should be very attractive to foreign investors if you look at the degree of changes happening at Japanese corporations," Hiromichi Mizuno, chief investment officer at the Government Pension Investment Fund, said this week in his first interview since taking his post in January. The GPIF is the largest fund of its kind in the world.
