Opposition parties said Monday they will jointly submit a no-confidence motion against health minister Hakuo Yanagisawa over the fiasco in which the Social Insurance Agency scrambled huge amounts of pension premium payment data.

The Democratic Party of Japan, Social Democratic Party and Kokumin Shinto (People's New Party) said they will submit the motion against Yanagisawa if the Lower House holds a planned plenary session Tuesday to pass a bill to reform the Social Insurance Agency.

"Health minister Yanagisawa is the top executive responsible for the act of fraud (over the pension fiasco) against the general public," DPJ Secretary General Yukio Hatoyama said.
