Dr. Yoshiro Nakamatsu —known to most of the public as Dr. Nakamats— of Tokyo, is likely the world’s most prolific inventor, with more than 3500 patents. His wig for use against attackers is a simple device, described in a patent:

“Wig for Self- Defense,” Japan patent 2007285622 (A), granted to Dr. Yoshiro Nakamats, November 1, 2007.

The patent’s technical drawings, reproduced here, are perhaps sufficient to explain the nature and power of the self-defense wig.

Many of Dr. Nakamats’s other inventions, including the inventor himself, are celebrated in the documentary film The Invention of Dr. Nakamats, which was released to the public in 2009.

Dr. Nakamats was awarded an Ig Nobel Prize for Nutrition in 2005 for photographing and retrospectively analyzing every meal he had consumed during a period of 34 years (and counting). The streak has now been extended to 44 years.
