Democratic Party of Japan President Ichiro Ozawa said Wednesday his party will be prepared for the possible dissolution of the Lower House and general election following Prime Minister Shinzo Abe's surprise resignation announcement.

Ozawa also reiterated that the DPJ's opposition to extending the special antiterrorism law that will expire Nov. 1 has not changed, regardless of the government's leadership change.

"You never know when the Lower House will be dissolved, so it is a matter of course for a politician and a political party to take all possible measures to be prepared for an election," the opposition leader told a news conference, adding the DPJ "is hoping for a general election as soon as possible."
