Some people think entrepreneurship is dead in Japan. They may change their tune if they watched the variety show "Medekin" (Fuji TV, Sun., 4:05 p.m.). The title is a play on the Japanese word "demekin," which refers to a bug-eyed goldfish, but the operative morpheme is "kin," meaning "money." The show profiles people who have come up with ideas that made them instantly rich.
