<![CDATA[The preservation of Tana Toraja customs faces increasing challenges from modernization, social change, tourism commercialization, and digital transformation, which may alter cultural meanings, customary authority, and intergenerational knowledge transmission. This study aims to analyze the preservation of Tana Toraja customs through the integration of cultural identity, customary practices, community participation, cultural education, tourism, and digital technology. The analysis draws on the perspectives of cultural-identity, intergenerational cultural transmission, and cultural-heritage preservation to understand the continuity of tangible and intangible cultural values. This study employs a descriptive qualitative approach using a literature review of relevant scientific journal articles, academic books, and scholarly publications. The literature is classified, compared, and thematically synthesized, while cross-source comparison and triangulation strengthen the consistency of the interpretation. The findings reveal that the sustainability of Tana Toraja customs rests on the interconnection of three central cultural elements: Tongkonan as a center of collective identity and symbolic authority, Rambu Solo’ as a space for expressing social and spiritual values, and Tominaa as a guardian of ritual language and customary knowledge. Their continuity is supported by community education, family involvement, youth participation, and the transmission of cultural knowledge across generations. Tourism and digital-technology offer opportunities for cultural documentation, education, and wider public access. However, without community participation and respect for customary contexts, these developments may encourage commodification and weaken cultural meanings. The study concludes that preserving Tana Toraja customs requires more than maintaining physical artifacts or ritual performances; it requires sustaining cultural meanings, social functions, indigenous knowledge, and community participation while adapting responsibly to-modernization. The novelty of this study lies in its conceptual synthesis of Tongkonan, Rambu Solo’, and Tominaa with intergenerational transmission, community participation, tourism, and digital transformation within an integrated perspective on cultural preservation. This synthesis positions customary preservation as a dynamic process of cultural continuity and adaptation]]>
