This paper explores an innovative cross-cultural collective creation teaching model through the analysis of the"Wharf Workshop"project conducted by Japanese playwright and director Macoto SATOH at the Yokohama Wakabacho Wharf Theater.Utilizing case studies and participant observation,the study delves deeply into the workshop's structure,pathways,and methodologies.The research reveals that the"Wharf Workshop,"centered on the core principles of sharing,networking,and Transboundary,provides a platform for participants from diverse cultural backgrounds to focus on problems and exchange ideas.By employing an integrated curriculum and a work-oriented approach,the workshop achieves harmonious integration through the cross-cultural collective cooperation in text reconstruction and body language expression.This model effectively promotes inno-vation in cross-cultural communication and collective creation,offering a practical and viable reference framework for contempo-rary theater education with significant practical significance and promotional value.
