In what follows, I first unpack the context of East Asia where fast economic growth, demographic transition, shifting public policies, and historical legacies as well as emerging trends of family norms and practices jointly influence children's and youths' everyday lives and well-being. I show that albeit intraregional and intrasociety heterogeneities, childhood is part and parcel of the modernization project in this part of the world, which has attracted concerted efforts of intense investment from the state and the family, shaping a trajectory of childhood that is increasingly scholarized. I then sketch the landscape of childhood and youth studies in this region, calling for the intervention of childhood sociology as an approach to bring young people's own perspectives, voices, subjectivities, and actions to the fore. This is followed by an introduction to four compelling contributions that offer rich and nuanced insights into the pains and gains, pressures and perseverance of the growing up experiences of the young in rapidly changing East Asian societies.
