Ibuka's first ideas can be found in his popular book, Kindergarten Is Too Late, published in 1971. By 1987, more than 650,000 copies had been sold with 82 printings. In addition to Kindergarten Is Too Late, the author published a picture book for mothers and a series of books based on round table discussions he led on education. Of them all, Starting at Age of Zero-Advice for Mothers on Good Education(1979) and The Missing Half of Education-Japanese Who Left Behind Their Humanity(1985) have enjoyed great success. The Missing Half of Education-Japanese Who Left Behind Their Humanity was such a big hit that it ran into its second printing just five days after publication. Within a month after that it was in its fifth printing. These books document the gradual evolution of Ibuka's opinions into a solid, well-developed theory. His primary interest changed from education in general to the education of children in the earliest stages of their development. He also shifted from the belief that intellectual development is the most important aspect of a child's education to the belief that nurturing the human elements of a child's personality should be our primary educational concern. From his unusual perspective, Ibuka discussed the issues of 'genetics and environment; the 'critical period: and 'pattern education; pointing the way towards a new era in education. He also addressed the subject a great deal of interest in academic circles. His book, Zero-Years-Old-Where Education Really Begins continued the discussion of how best to educate children. Published in Japan in November, 1986, it contains the latest information at the time and practical examples of his ideas.
Later in his life, he was inspired to write what would become his last book "From a Fetus" in 1992.
