Mikinosuke Kawaishi (?? ????, Kawaishi Mikinosuke, born 13 August 1899 – 30 January 1969) was a Japanese master of judo who achieved the rank of 7th Dan. He led the development of judo in France, with Shozo Awazu, and much of Europe and is credited with introducing the colored belt system for differentiating early grades. However, written accounts from the archives of London's Budokwai judo club, founded in 1918, record the use of colored judo belts at the 1926 9th annual Budokwai Display, and a list of ranked colored judokas appears in the Budokwai Committee Minutes of June 1927. Kawaishi visited London and the Budokwai in 1928, and was probably inspired to bring the colored belt system to France.[1] The Fédération Française posthumously awarded him 10th Dan in judo and jujutsu.
