Prime Minister Taro Aso's Cabinet lineup may look a bit subdued, but there's good reason for that: He deliberately picked low-profile politicians instead of factional bigwigs so he can lead them around like a "school teacher," experts said Wednesday.

"It seems this Cabinet is a bit too plain to be an election measure," said Nobuhiro Hiwatari, professor of political science at the institute of social science at Tokyo University.

"I think the aim is probably to form the Cabinet in which Aso can show his leadership to gain popularity" with voters, he said.
