It has been well known that Fusa Sekiguchi (1914-2013) developed her idea of “Human Protection (Ningen-Shug) ,” the central concept of her Philosophy of Home Economics(1977), from the concept of “Geborgenheit(Higosei) of O. F. Bollnow (1903-1991). Other than the works on the principles of Home Economics by Sekiguchi, previously Kawakami (1996) worked on Bollnow’s “Geborgenheit” and Itani (2013) recently discussed in the educational philosophical perspective. Sekiguchi’s interpretation of the concept of “Geborgenheit,” however, is not sufficiently discussed these factors : findings of other scholars and Bollnow’s manuscript contributed to Sekiguchi’s book, Philosophy of Home Economics (1977). In this paper we tried to rethink “Human Protection (Ningen-Shugo)”, the primary concept of Philosophy of Home Economics by Fusa Sekiguchi. Then we discuss how we could succeed and develop Sekiguchi’s concept in current Home Economics.
