Introduction to Social System Design

Summary of the Research Undertaken

This researcher studies the methodology to construct core question for social issues that do not have a "correct answer", and to grasp the solutions as oneness by breaking the shell of creativity and intuition (design thinking) for the well-being of the world and individuals. He researches a methodology called “social system design” that can be systematically proposed to the society as a new value (system thinking) and skills to carry on a project (project management).

Research Themes

  • Development and validation of methodology that emerge social innovation.
  • Development and validation of social design methodology to positively change the world.
  • Method to development and validate the concept of well-being-centered design.
  • Development of a methodology for social design of local currencies that improves the subjective well-being at local communities.
  • Development of the correlation between job engagement, subjective well-being, and corporate growth as well as its design methodology.
  • Development and validation of dialogue methods that promote social innovation.
  • Construction of a mechanism to enhance subjective well-being and revitalization of local communities and verification by promoting social-capital-based connections among local residents.
  • Development of architecture to establish "ba" design and to enhance subjective well-being of local residents for revitalization.
  • Development and verification of a methodology to emerge innovation using system and design thinking.
  • Development and verification of financial methods in which finance creates new value to enhance subjective well-being of local residents.

Details of the Research

In order to realize the society where both the earth and individuals are in the state of well-being, the researcher studies the academic framework of design thinking, systems thinking and project management to explore solutions to various social issues, which is creative methodologies to be put into practice. The methodology is called social system design.

The central concept of the methodology is "well-being-centered design", which is advanced from the human-centered design, to design well-being both for the earth and individuals.

Since quality and quantity of human connections is scientifically proved to correlate with subjective well-being, the researcher focuses upon design of local currency that mediates local socio-economic activities to strengthen social capital for enhancing subjective well-being. The researcher particularly pays attention to the academic approach to identify currency for paying-it-forward, and are studying how it is related to enhance the user's subjective well-being.

The researcher also studies the correlation between job engagement, subjective well-being of corporate employees and corporate growth in the fields of the design methodology and validation. Studies are forwarded to the fields of the dialogue theories to enhance social innovation.

The researcher is member of the Japan Academic Society of Regional Revitalization, and councilor of the Japan Creativity Society.
