This presentation traces the theoretical and methodological evolution of my research into collective remembering and UK-Japan reconciliation practices from a discursive psychological perspective. Beginning with a social constructionist foundation, my work has progressively engaged with sociocultural theory, positioning theory and actor-network theory to explore how memory is not passively stored but actively constructed through discourse, interaction and material and embodied practices. I examine how reconciliation processes unfold in post-Second World War contexts, where historical narratives are dialogically negotiated, contested and reimagined. Central to this inquiry is the argumentative nature of remembering—how individuals and groups justify, challenge and reframe the past in ways that shape both personal and collective identities. The research foregrounds the performative and embodied dimensions of memory, attending to how voice, affect, material artefacts and spatial arrangements participate in the co-construction of meaning. By situating memory and reconciliation within everyday talk and institutional narratives, the work highlights the entanglement of discourse with materiality and agency. The presentation offers a reflexive account of key theoretical tensions and methodological shifts encountered along this journey, including the challenges and affordances of interdisciplinary integration. Ultimately, it argues for a more nuanced, dynamic understanding of memory and reconciliation as situated, contested, embodied and materially mediated practices. This approach not only enriches discursive psychological inquiry but also contributes to broader debates on how societies remember, reconfigure and reimagine their pasts.
