The Kumon method, developed by educator Toru Kumon, is the largest mathematics and language educational system in the world.[1] As of 2009, over 4 million students were studying under the Kumon Method at more than 26,000 Kumon Centers in 46 countries.[2]



In 1954, Toru Kumon, a Japanese high school mathematics teacher, began to teach his eldest son due to his problems in mathematics at school. Kumon developed the Kumon Method. In 1956, Kumon opened the first Kumon Centre in Osaka, Japan with the help of parents that were very interested in the Method. In 1958, he founded the Kumon Institute of Education, after which Kumon Centres began to open around the world. Since 1956, some 20 million students were enrolled in Kumon. Today, there are around 4 million Kumon students worldwide. At present there are 1500 Kumon Centres in the USA, and there are a total of 26,000 Kumon Centers in 44 countries. This list of countries includes USA, Canada, Mexico, Brazil, Argentina, United Kingdom, Spain, Germany, South Africa, Australia, New Zealand, Japan, South Korea, Philippines, Singapore, Malaysia, Indonesia, India and more.

The programs

Kumon is a math and reading enrichment program. Students do not work together as a class, but progress through the curriculum at their own pace, moving on to the next level when they have achieved mastery of the previous level. Mastery is defined as speed (using a standard completion time) and accuracy.[3] They take an achievement test at the end of each level.

Company value

The Kumon family, led by his wife Teiko, own 60 percent of the company. Forbes magazine estimated in March 2009 that the entire company was currently worth over $650 million.[4]

Variation of programs throughout the world

The Kumon language program varies regionally. For example, the Chinese reading program in Mainland China is different from the Chinese reading program in Hong Kong and in Singapore,[6] [7] [8] and the English program in the U.S., Canada, and the Philippines varies from the English program in the United Kingdom. Additionally, Kumon Korea has other subjects, such as science, calligraphy, Korean, and Chinese characters, which are not available elsewhere.[9]

The Math program also differs. The math program for most countries goes up to Level O and Level X.[10] [11] [12]However, in Japan, the math program is available up to Level V. [13]

The Kumon logo is known as the "Thinking Face", embodied into its name as the letter "O." This "Thinking Face" symbolizes not only the face of a child, but also that of an adult. Kumon's corporate color is sky blue, which represents human intellect, integrity and earnestness.
