Out of 100 people who voted for the ruling Liberal Democratic Party in the 2005 general election, 68 of them now think the government should be changed in the Aug. 30 poll, survey results showed Friday.

The Kyodo News survey of 50 men and 50 women in their 20s to 70s from across Japan conducted between July 22 and 31 found that many prefer a change and expressed support for the reform initiatives four years ago of then Prime Minister Junichiro Koizumi.

In seeking a change of administration, they cited such reasons as wanting the LDP to reflect on what it has done and the hope that a new administration will end the "amakudari" practice in which bureaucrats land plum jobs after retirement in industries they once oversaw, often resulting in widespread corruption and conflict of interest.
