Upper house lawmaker Yoriko Kawaguchi may return to the position of foreign minister, Japan's press has reported.
According to Reuters, incoming prime minister Shinzo Abe is considering asking the former holder of the office to join his new cabinet.
With tensions currently running high between Japan and China over an ongoing territorial dispute Abe has called for the country to take a tougher stance against its Asian neighbour.
He may be hoping he has an ally in Kawaguchi, who served as foreign minister under prime minister Junichiro Koizumi between 2002 and 2004.
After winning the general election earlier this month, he is now in the process of putting together his cabinet, with political commentators expecting it to be formally inaugurated on Wednesday.
Abe and his conservative Liberal Democrat Party have come to power on the promise of increased public spending, despite the fact that Japan already has the largest debt burden of any country in the world.
