As the world's most aged society, Japan can play a leading role in advising other countries facing a similar demographic challenge in the future, according to a British professor sitting on a new government panel on human resources.

Lynda Gratton, a professor of management practice at London Business School, said Japan needs to aim at boosting the participation of women and people over the age of 60 in the workforce through its economic policies.

"Japan might be the first society to age. But every single country in the world will go through the same process that Japan has gone through," Gratton said in an interview Tuesday.
