New Kansai International Airport Co. is seeking to attract the state-run retirement fund to a sale of two airport concessions that could raise as much as ¥1.2 trillion.

The Government Pension Investment Fund, the world's largest, with $1.2 trillion under management, "is a strong future candidate investor for infrastructure, including these airports," said Shinichiro Okada, who is overseeing the concession sale for New Kansai. He declined comment on whether the parties are currently in talks.

"Airport concessions will be a new asset class that would attract pension funds in Japan," Okada, who formerly worked at Macquarie Group Ltd.'s infrastructure business in Japan, said Monday in Osaka.
