One of the busiest people on TV right now is Daigo Naito, a 30-year-old who dresses and gesticulates like a rock star while speaking in the tones of a narcotized 16-year-old. Daigo isn't a comedian, though his droning delivery elicits laughs, and he's not really a rock star, though he did start his show biz career with the intention of becoming one. His ubiquity is based on one thing: pedigree.

Daigo is the grandson of late Prime Minister Noboru Takeshita, and his career as a TV star took off when Takeshita's widow gave him permission to use grandpa's name when selling himself as . . . whatever. For a decade before that, Daigo struggled to make it in the world of visual-kei, a rock subgenre whose musicians dress like manga characters and play sweetened heavy metal. He fronted a group called Jzeil (pronounced "jail") and recorded an album written and produced by superstar Kyosuke Himuro, but nothing came of it. As soon as he revealed that he was the grandson of one of the most notorious "dons" of the Liberal Democratic Party, however, offers for television work poured in.

Progeny of famous people are as common in show business as divorce lawyers, but most "juniors" put in the appearance of having some sort of skill, be it acting, singing or weather reporting. Daigo has only the Takeshita name, which isn't his since his mother, Noboru's daughter, gave it up when she married. His blase-rocker act is meant to be an ironic comment on his respectable lineage, but there's no disrespect involved. Daigo owes his dead grandfather his livelihood.
