Democratic Party of Japan President Ichiro Ozawa kicked off the Diet debate Wednesday by concentrating on his party's policy pledges and lambasted Prime Minister Taro Aso for directing questions to the DPJ in his policy speech earlier in the week.

"Prime Minister Aso's policy speech had neither principles, vision nor policies. The only specific thing was a defamatory stance toward the DPJ," Ozawa said.

He said if the DPJ gains power it will allocate ¥20.5 trillion — roughly 10 percent of the current budget — to achieving its policy pledges, including a ¥26,000 monthly child-rearing allowance.
