The evolution of VR, hologram, and light projection technologies is astonishing, and when combined with AI, it is becoming increasingly difficult to distinguish between reality and <Kyo zou>. Discussions on how to perceive this phenomenon in light of such technological advances have scarcely even begun. This paper conceptualises the "Ba" in Japan where AI-generated "Information-oriented legal entity" and natural persons co-innovation as a <Kousou Ba>, exploring how social interaction within this "Ba" forms <Chu Rin>. It reveals the phenomenon of "Tachiarawareru" manifesting within this <Kousou Ba>. In a culture where the deceased have co-innovation alongside the living since ancient times, the ethics surrounding these technologies differ entirely from those in other countries. It has been demonstrated that the key lies in the "Chu Rin" between "Information-oriented legal entity" and the <Kousou Ba>.

This paper focuses on hazardous disaster waste generated by uncertain natural disaster risks, including the Great East Japan Earthquake and the Noto Peninsula Earthquake, severe flooding, and typhoons. In particular, the risks of such natural disasters vary from region to region. The types of objects that could potentially become hazardous disaster waste also vary in the nature of the damage and the degree of adverse social impact. Therefore, this paper examines approaches to the complex risks surrounding hazardous disaster waste generated by uncertain natural disasters. Specifically, this paper examines and considers the importance of forming and role of risk communities in peacetime in order to address these complex risks, as well as the necessity of collaboration between local government BCP (Business Continuity Plans) and the PRTR (Pollutant Release and Transfer Register) system, and offers new policy implications.
