Toru Kumon
was a Japanese mathematics educator, born in Kōchi Prefecture, Japan.〔(【引用サイトリンク】title=The Birth of Kumon: The Story of Toru Kumon )〕 He graduated from the College of Science at Osaka University with a degree in mathematics and taught high school mathematics in his home town of Osaka.〔 In 1954, Kumon began to teach his oldest son, who was doing poorly in mathematics in primary school, and developed what later became known as the Kumon method.
This method involves repetition of key mathematics skills, such as addition, subtraction, multiplication, and division, until mastery is reached. Students then progress to studying the next mathematical topic. Kumon defined ''mastery'' as being able to get an excellent score on the material in the time given. Kumon strongly emphasised the concepts of ''time'' and ''accuracy''.
As a result of the method, other parents became interested in Kumon's ideas, and in 1956, the first Kumon Center was opened in Osaka, Japan. In 1958, Toru Kumon founded the Kumon Institute of Education, which set the standards for the Kumon Centers that began to open around the world.〔 Since 1956, more than 19 million students have enrolled in Kumon Centers worldwide. Toru Kumon died in Osaka on July 25, 1995 at the age of 81, from pneumonia.〔
Asteroid 3569 Kumon is named after him.〔.〕
