The Finance Ministry will probably oppose raising interest rates during the Bank of Japan's Policy Board meeting Friday, Finance Minister Kiichi Miyazawa said Wednesday.

"I think we are going to say that now is not the right time (to raise rates) if anything, though it is not certain yet," Miyazawa told a regular news conference.

Under the BOJ Law, representatives from the ministry and the Economic Planning Agency are allowed to attend Policy Board meetings and state opinions, albeit without voting rights.
