Most observers are betting the Democratic Party of Japan will win the Aug. 30 Lower House election, with their focus now on just how big the DPJ's victory will be.

However, some say the DPJ will not score the massive landslide as indicated in the latest opinion polls.

"The people want to give the DPJ a chance, they want to see a change in government power," said Rei Shiratori, president of the Institute for Political Studies in Japan.
