In the aftermath of farm minister Takehiko Endo's resignation Monday, only a week after Prime Minister Shinzo Abe reshuffled his Cabinet, Chief Cabinet Secretary Kaoru Yosano called on his colleagues to behave appropriately in their positions as government ministers.

Asked what the government should do to cope with its lack of crisis management ability, Yosano said in a recent interview, "Each Cabinet member needs to make actions and comments based on judgment worthy of a minister."

Following Endo's resignation, Yosano also told a news conference that the government needs to consider a better system to detect missteps that could cause scandals, although he did not outline the details of such a system.
