Sōka Gakkai was founded as the Sōka Kyōiku Gakkai (創価教育学会, lit. "Value-Creation Education Society") on November 18, 1930 by Japanese educator Tsunesaburo Makiguchi and his colleague Josei Toda. Makiguchi sought to reform Japan's militaristic education system into a more humanistic one that would support the full development and potential of Japan's youth. His ideas on education, and his theory of value-creation (創価, sōka), are explored in his 1930 work Sōka Kyōikugaku Taikei (創価教育学体系, The Theory of Value-Creating Pedagogy). In Nichiren Shoshu Buddhism, he found a religious philosophy that reflected his educational theories, which led to the establishment of the Sōka Kyōiku Gakkai. Eventually, the focus of the organization began to shift, as Makiguchi came to the conclusion that the practice of Nichiren Shoshu Buddhism itself could allow each individual to develop their potential within and attain Buddhahood. However, Makiguchi and Toda's thinking was in direct conflict with the goals of the state. When the Japanese government more rigorously enforced Shinto's position as the state religion (State Shinto) with the enactment of the Religious Organizations Law of 1939, a move designed to impose stricter governmental controls over religions,^[5] and began to demand that all citizens enshrine Shinto talismans in their homes^[6] Makiguchi, Toda, and 18 other Sōka Kyōiku Gakkai members resisted, refusing the talismans. For refusing to cooperate with the government by compromising their religious beliefs, the two educators were sent to prison. Makiguchi died there at age 73; Toda was later released and, after World War II, rebuilt the organization, renaming it Sōka Gakkai to reflect the extension of its membership beyond educators only. Over the years, the Sōka Gakkai experienced a period of rapid growth in Japan. An organization, Nichiren Shoshu of America (NSA, later also called Nichiren Shoshu Academy, Nichirenshoshu Sōkagakkai of America, and finally Sōka Gakkai International – USA), was formally organized in the United States on October 13, 1960. Today, Sōka Gakkai International and Nichiren Shoshu have parted ways. SGI now has a membership of somewhere between 100,000 to 300,000 practitioners in the United States.^[7] Sōka Gakkai International (SGI) was founded in 1975 as the International Buddhist League to act as the international leadership of national Sōka Gakkai organizations.
