<p>This study investigates how the interplay between teachers and Korean kindergarten culture shapes a teacher learning community. Data were collected through group interviews, in-depth individual interviews, and participant observations, allowing for a rich exploration of both collective and individual perspectives. The data were analyzed iteratively, with a focus on the cultural and relational dynamics embedded within the teaching learning community. The findings underscore the critical role of emotional support, constructive dialogue, and balanced relationships within a community operating in a predominantly female, traditionally hierarchical culture. The study also highlights the essential leadership roles of lead teachers, demonstrating how humility and a balance between collectivism and individualism foster trust, align shared goals, and support collaborative growth. Furthermore, the study explores the dual aspects of Korean collectivist culture, emphasizing its role in promoting equitable education for children and addressing parental pressure, while paradoxically limiting teachers’ autonomy in decision-making. This dynamic is particularly evident in curriculum alignment, where teachers of the same age group collaborate to ensure cohesive educational practices. This analysis provides valuable insights into the processes that foster effective communication, collegial relationships, and a balanced sense of autonomy among teachers. These findings also offer practical implications for enhancing professional growth, leadership development, and collaboration within TLCs in culturally similar contexts.</p>
