Abstract: In current planning, design and construction practices, an integrative development trend between the smart city and TOD modes was formed under the concept of cyber-physical-social integration. A new trend of smart TOD mode has developed. Although a smart TOD mode is frequently practised and explored, few theoretical studies on the planning, design and execution methods of TOD modes indicatea weak research basis. Smart city projects in urban rail station areas have become essential and unique. Such projects not only have the background of low-carbon ecological spatial mode but also enable an important platform integrating smart technological applications and low-carbon ecological development concepts and smart innovation, development and transformation. On the one hand, important values are associated with developing rail station areas. On the other hand, it is vital to transform and innovate the overall urban structure. In recent smart city constructions in Japan, many pilot projects used rail station areas as the spatial carrier, which objectively creates rich plans, practices and explorations of smart TOD. Moreover, enlightened practice must bring research results in theory and methods from the perspective of smart TOD and a summary of methods and experiences of design construction units. These achievements have exploration connotations when combining TOD and smart city modes. In rail station areas, future oriented TOD mode reflects the innovative integrated development trend that uses smart technological applications as the technological basis, and social connotation and humanized spatial planning layout as the material carrier. The smart TOD planning and practice experiences in rail station areas in Japan can be summarized into four aspects: structure, function, space and mechanism. Firstly, the spatial form that combines smart city and TOD mode involves the expanded hierarchical structure and tight form layout. Secondly, the rail station area depends on functional integration and innovation of smart technology, encouraging diverse functions and the implantation of innovative business forms. Thirdly, the smart development trend integrating scenes and public spaces in the space design is developed. Fourthly, innovative exploration of cooperation mechanisms of smart city projects in rail station areas is undertaken. It involves two processes: 1) data-driven integrated cooperation mode and 2) smart city PPP based on government-enterprise cooperation and industry-university combination. In China's practices, the integration between smart city construction and TOD planning construction is nascent. The influences of smart city development on TOD regions have not been thoroughly explored. In particular, there is less focus on changes inspatial structure. Hence, smart city construction based on rail station areas in Japan can provide rich references. First, the planning layout of smart city construction focuses on the overall and regional aspects of stations relative to experiences in Japan. The evolutionary trends of spatial structure within the smart TOD mode require further exploration. Second, for service improvement and functional innovation, the smart TOD functional organization mode with innovative connotations and service groups is explored based on rail station areas by consideringTOD4.0 and other concepts. Third, the most critical thing in space design is highlighting the value of integrated scene innovation in rail station areas. The smart technological applications, station space optimization and residents' activity changes are better integrated to meet the smart city construction needs. Finally, regarding cooperation mechanisms, combining a smart city's implementation and promotion plan and developing rail station areas was explored to strengthen target performances of smart city construction to subjects related torail construction, operation and development.
