Yoshiro Nakamatsu

In some interviews, Nakamatsu has described his "creativity process", which includes listening to music and concludes with diving underwater, where he says he comes up with his best ideas. He then records them while underwater. Nakamatsu claims to benefit from lack of oxygen to the brain during his dives, making inventions "0.05 seconds before death." He also claims that his "Calm Room," a bathroom constructed without nails and tiled in 24-karat gold, encourages creative thinking by blocking television and radio waves. He also has an elevator in his house that he claims helps him think better, although he strictly denies that it is an elevator and describes it as a "vertical moving room". He predicts that he will live until the age of 144. ==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 ..." (1964) • "Enerex" - System for generating hydrogen and oxygen • "PyonPyon" - Jumping shoes with leaf springs on their soles • "Cerebrex" armchair, a chair that supposedly improves mental function such as calculation and thinking by cooling the head and heating the feet • A toilet seat lifter • A condom with an embedded magnet, supposedly "improving sensitivity" as "electricity is generated in the blood vessels in the female organs by Fleming's left-hand rule" • A protective envelope for floppy disk (1975-1983), and a head-cleaning floppy disk (1981-1988) • A CD for supposedly "enhancing brightness or sexual function" • A cigarette-like device for supposedly "activating the brain" • A pillow preventing falling asleep while driving (an air compressor strapped to the cars headrest, forcibly feeding air to the driver) • A peephole in a sheet of material, described as a "oneway visible shielding object" • Spectacles in the shape of eyes, so that the user appears to wear no spectacles • A "wig for self defense" — a strip and a weight are attached to a wig. 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. ==Personal life==

Nakamatsu is the son of Hajime Nakamatsu, a banker, and Yoshino Nakamatsu, a teacher who provided early tutoring in mathematics and science and encouraged him to begin inventing. 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. ==Political aspirations==

Nakamatsu is a perennial political candidate. In 2004 he told the Japan Times that "politics is a part of inventions," explaining that it is an "invisible invention" along the lines of concepts such as education and happiness. Since 1995 he has unsuccessfully campaigned multiple times to be elected Governor of Tokyo, including, at an age of 96 years, in the 2024 election where he was ranked 11th. He has also campaigned unsuccessfully for election to the House of Councillors, the upper house of the National Diet. In 2010 and 2013 he ran as a candidate of the Happiness Realization Party. ==Media coverage and recognition==

In 2010, Nakamatsu claimed he had been granted an honorary title by the Sovereign Military Order of Malta, and introduces himself as "Sir Dr. NakaMats", although his claim has been denied by a representative of the order. In 2019, Nakamatsu was featured in a mini-documentary by popular YouTube channel Great Big Story, in which Nakamatsu discussed some of his successful inventions and demonstrated his creative process. , it had more than 4.2 million views. ==See also==
