This study reviews literature on of diversity and inclusion (D&I) practices on corporate sustainability in Japan and Malaysia. The increasing focus on corporate sustainability has spurred interest in understanding how D&I practices shape organizational outcomes. While research in this area has been extensive in the West, there is a lack of comprehensive understanding of D&I in Asian contexts, particularly in Japan and Malaysia. This study aims to explore how D&I practices contribute to corporate sustainability within these two contexts. Using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) protocol, the study systematically reviews literature from 2013 to 2024, 28 articles were selected for analysis. Through content analysis, five themes emerged: cultural contexts of collectivism vs. individualism, economic context, regulatory context: D&I Legal Frameworks and Corporate Law Influence in Japan and Malaysia, educational and community benefits, regulatory and organizational support, and post-pandemic workforce dynamics. Findings revealed the diversity and inclusion practices bringing positive impact to the organizational performance. However, cultural barriers and the need for deeper shifts in workplace norms remain critical challenges. This study offers a comparative review of D&I practices in Japan and Malaysia, revealing critical insights that can inform policies, organizational strategies, educational programs, and further research.
