You must spread some Reputation around before giving it to sublight again.
One cool guy is former Megadeath lead guitarist Marty Friedman
Also that half-black enka singer Jero is only 28 according to his bio; he could easily be a nobody in 5 years however.... such is the fate of tarento. No one hears much about Kent Gilbert, Kent Dericott, Mr. Wiki (the Sri Lankan), Chuck Wilson (the gay bodybuilder/fitness advocate) ... let alone 2000 sensation Bob Sapp.. these days.
Although she's not a "real gaijin", Agnes Chan seems to shown a certain degree of staying power and with her fashion businesses in Japan .. success.
