Inventions

Nakamatsu is a prolific inventor, and he even claims to hold the world record for number of more than 3,200 inventions. While his claim to a "world record" has been described as a record for patents by several media articles, several other sources do not list Nakamatsu among the world's most prolific inventors (he has six patent families).

Among Nakamatsu's early inventions is the Shoyu Churu Churu, a siphon pump used in the home to move soy sauce from large containers to smaller vessels for cooking and serving. His patented inventions include: Juusyoku Record (, ) – An optical sound media which uses a printed paper sheet instead of transparent film (1952) "Magnetic record sheet" - "a method for forming signal record track comprising a number of spiral signal track loops ..."

The wearer swings the wig to hit an attacker. Love Jet - A sexual enhancement product which he created out of concern about Japan's declining birthrate. In a 1995 interview, he explained that the purpose of the aphrodisiac was "to save Japan".

Floppy disk

Upon the basis of the Juusyoku Record patent issued in 1952, Nakamatsu claims to have invented the first floppy disk However, what Nakamatsu patented in 1952 was a paper for optical sound player. He also says to have licensed his floppy disk to IBM in 1979, Another IBM spokesman, Brian Doyle, said that the company licensed 14 patents from Nakamatsu and those patents do not have anything to do with the floppy disk.

He studied engineering at the University of Tokyo. In September 2015, Nakamatsu appeared at the awards ceremony for the Ig Nobel prizes, where he performed a song about his medical condition.
