Since the emergence of life, knowledge succession has served as a fundamental mechanism for survival and evolution. While biological knowledge is transmitted through genetic inheritance, human societies have developed increasingly sophisticated modes of knowledge transfer—from oral traditions and written records to digital technologies. In contemporary Japan, declining birth rates, population aging, and increasing labor mobility have resulted in persistent workforce shortages and higher employee turnover. Consequently, traditional long-term, one-on-one on-the-job training (OJT), which historically served as the primary mechanism for transmitting tacit knowledge, has become increasingly difficult to sustain. Organizations across diverse sectors are therefore striving to develop new institutional and technological mechanisms that ensure the continuity and evolution of knowledge beyond individual mentorship relationships.
This special issue explores knowledge succession not merely as the preservation of past experience, but as a dynamic process that generates new value through interaction, reinterpretation, and recombination. The nine contributions presented here examine diverse domains—including manufacturing, family businesses, M&A integration, nuclear research, elderly care, education, and information technology—and reveal how knowledge is created, shared, transformed, and sustained under changing conditions.
Several articles highlight the role of digital technologies, such as AI systems, ontologies, and data-driven platforms, in externalizing tacit knowledge and facilitating its transfer across organizational and generational boundaries. At the same time, other contributions emphasize the enduring importance of human factors—organizational culture, shared context, interpersonal trust, and narrative communication—in enabling deeper understanding and effective succession.
Furthermore, this issue addresses the temporal dimension of knowledge succession. Studies of long-standing institutions and family enterprises demonstrate how enduring principles and traditions can be reinterpreted to support innovation rather than constrain it. Across these varied contexts, knowledge succession emerges as a multifaceted process involving socialization, articulation, systematization, and internalization.
Collectively, the contributions suggest that successful knowledge succession in the contemporary era requires an integrative approach that combines technological support, organizational design, and human engagement. By presenting concrete cases from multiple fields, this special issue aims to provide a foundation for rethinking how knowledge can be sustained and evolved in the age of artificial intelligence and societal transformation.
