Hello World Japan: Love Potions, Wigs and So Much More

At 88, Dr. Yoshiro Nakamatsu, a.k.a. Dr. Nakamats, is something of a celebrity in Japan. He's a prolific inventor, claiming more patents than anyone else in history. Some of his inventions, like the floppy disk, are absolutely legit, and he created a suction device that has become a staple in Japanese homes for handling things like soy sauce and kerosene. Others, well, there's a wig with a built-in shuriken for self-defense. Then there's a sex potion, LoveJet 69, that promises orgiastic pleasures and, as if that weren't enough, increased life span. Maybe they're related. 

Hello World's host, Ashlee Vance, paid a visit to his home and lab in the Tokyo suburb of Setagaya. Dr. Nakamats took Vance on a tour of his invention museum and patent shrine and allowed him to try out his cancer-curing BarcaLounger. It's unclear if any cancer was cured, but Dr. Nakamats certainly put on a good show.
