Nobuko Kan's book, "Just what will change in Japan after you become prime minister, dear," published by Gentosha, aims barbs at her husband's performance as prime minister, including an admission that "even a family member couldn't have given his general policy speech a passing grade," the Mainichi Shimbun reported Friday.
"Actually, he is more suited to being party secretary-general or head of the policy research committee than being the leader of the party," Kan wrote.
"His biggest problem is that even if he's talking with someone older than him, he gets angry in public." The book reads. However, the first lady concedes that "lately he's really become an adult."
Prime Minister Kan, responding to a question from reporters about the book Wednesday, said: "I'm too scared to read it."
