Self-effacement has become an important topic in cross-cultural social psychology. However, descriptive characteristics of self-effacement have rarely been investigated. Based on representative network survey data, this study examined to whom Japanese people efface themselves. The results indicated as follows: 1) people tend to efface themselves to their neighbors or mere acquaintances more than to their spouses, colleagues, or best friends; 2) the duration of the relationship correlated negatively with self-effacement; 3) the relationship between psychological intimacy and self-effacement shaped reversed-U; and 4) people tend to efface themselves to maintain or attenuate their status difference, i.e., people efface themselves more to colleagues when the people considered those colleagues to be superior to them, and also to best friends when they considered those friends to be inferior to them.
