With the acceleration of globalization, international exchanges and teaching cooperation between universities have become increasingly frequent. Especially in the field of architecture disciplines, it is very common to carry out joint design teaching with urban design as a multi-disciplinary, open and inclusive topic, which has become an important way to explore urban design education and professional talents. International urban design workshop of Tokyo Tech with a long history. Among them, Tokyo Institute of Technology, Tongji University, Southeast University and South China University of Technology are the core members. Each year, another university (usually the university in the city where the design base is located) is invited, based on the teaching traditions and characteristics of each school, teachers and students around the real city market area, from the perspective of urban design and architectural renewal, for a total of three stages, three weeks of teamwork training of urban design. The process emphasizes the collision and game of different concepts, the expansion and innovation of design thinking, and the improvement of design expression ability. Based on personal experience and results, this paper explores the academic exchanges and development paths of Tokyo Institute of Technology and South China University of Technology, summarizes and compares the similarities and differences between the design objectives, methods and characteristics of urban design teaching in various universities, and proposes the teaching reform and innovation of urban design. The conception provides a diversified perspective for the current development of urban design education in China.
