In 1916, Kotaro Honda invented KS magnet steel, which had three to four times the coercivity of the strongest magnet at the time. This "KS" is an acronym for Kichizaemon Sumitomo, who donated research funds to the 2nd Division of the Provisional Institute of Physical and Chemical Research. The throne position was lost to MK magnet steel developed by Professor Tokushichi Mishima in 1931. However in 1933, Honda invented New KS magnet steel which had even higher coercive force. The development of KS magnet steel and New KS magnet steel is the pioneering invention of material science in Japan, and is said to be Japan's 10 greatest inventions.
