Early modern Kyoto was home to the Kōgakusho (Center for Filial Studies), a society for moral education with its headquarters at the Suika Tenmangū and Kawase Yūzan (1791-1857) at its helm. While the large number of publications by the society have caught scholars' attention and have earned it praise as "a stronghold of filial education", there is in fact very little known about its ideology, regulations, and activities.This paper will provide an introduction and complete tran-scription of the society members' handbook Jitsumeiki (1849). By doing so, it aims not only to elucidate the general workings of the Kōgakusho, but also to provide a new primary source that can aid further study into the educational landscape of Kyoto in the early modern period.
