Miyake Kunihiko says that it is. (Link)
I say, "Not according to the opinion polls, it ain't." (Link)
Miyake-san (whom I like a lot, for a good many reasons) has gone overboard in his utterances, carried away by rhetoric and emotion...just like the man who is ever seeking Miyake-san's advice, Prime Minister Abe Shinzo (no exaggeration: Miyake-san is the most important of Abe's private sector security advisors). The PM has been flying off the handle a lot of late, with Chief Cabinet Secretary being forced to step in and reel back expectations.
Many thanks to Elaine Kurtenbach for sending me her questions.
