Internal Affairs and Communications Minister Kunio Hatoyama reiterated Wednesday he doesn't want Yoshifumi Nishikawa to remain president of Japan Post Holdings Co., indicating he might quit if Prime Minister Taro Aso sticks to his decision to reappoint Nishikawa.

"Words of a politician carry much weight," Hatoyama said. "I will not compromise my creed. I have the power to approve (the appointment of the Japan Post president). I won't approve (Nishikawa)."

Nishikawa's term expires this month.
