Kizaemon Aruga is known for his empirical studies on “Ie” that utilizes monograph, but his political standpoint has scarcely been remarked upon. However, Aruga carried out many discussions on “Ie” and “democracy” in a style different from that of postwar reformists and conservatives. This paper analyzes the formation of such discussions by Aruga and also explores the position of his discussions in the postwar family studies. As a result of examination, Aruga's awareness of issues and viewpoints in which “Ie” is “democratized (modernized)” is revealed. In the concluding section, Aruga's viewpoints are positioned not as democratization of “family” but as democratization of “Ie” and his views are discussed.
