HOSHINO Kasui (1885-1939), who graduated in mathematics from Tokyo Higher Normal School, wrote and published The Study of Geometry by the CHART System, a math study book for entrance exams, in 1929. Since then, the study books, which are named CHART System, have been published for over 75 years. Therefore, it can be said that the CHART System is an established method of study used in study books. However, there exists no previous research on the CHART System or its founder, HOSHINO Kasui. This paper clarifies the following two points: 1) Origin of the CHART System: The CHART System was developed by Hoshino Kasui in cooperation with his business involving the publication of a monthly magazine and several study books for entrance exams as well as through his managing and teaching experiences in a cramming school. 2) Features of the CHART System: The features of the CHART System become evident upon comparing the solution provided by Hoshino and that provided by a previous study book with regard to the same question. Hoshino led students to the solution by providing CHARTs, which were precepts based on solution scenarios that did not require dependence on rare inspiration. Hoshino's CHART System, which he extracted from numerous solution scenarios, was the first step in the compilation of solutions to questions in study books into a manual.
