  　View Summary

  We analyze the ties between 4000 Japanese corporations in the time period from 2004 until 2013. We combine data about the board composition with ownership relationships and indicators of corporate profitability. The board network exhibits some clustering, which can partly be explained by ownership relations, and a tendency to form ties to other corporations from the same sector. Connectivity in the board network (corporate board interlocks) and ownership network (shareholdings) does have an influence profitability. Firms that are linked to peers with above average profitability are more profitable than firms in other relationships. Hence, network effects partly explain why board interlocks and ownership ties are not always beneficial.

  　View Summary

  We investigate the dynamics in the networks of Japanese corporates and its
  interplay with the appointments of female board members. We find that corporate
  boards with women show homophily with respect to gender while the respective
  firms often have above average profitability. We also find that new
  appointments of women are more likely at boards which observe female board
  members at other firms to which they are tied by either ownership relations or
  corporate board interlocks.

  　View Summary

  Through participatory simulation studies, we analysed various factors as being necessary for social system models, such as rational decision-making, habitual behaviour and unexpected decisions by humans. In early 2020, when these studies were underway, a new coronavirus outbreak occurred, and the government declared a state of emergency. In response to this situation, we built an infectious disease policy model for the new coronavirus infection based on agent-based health policy gaming & simulation to predict the impact of human behaviour and policy.

  　View Summary

  In this research, we analyze the influence of corporate governance on asset prices through information technology and empirical analysis. As a result of intensive analysis, we made findings that companies that play a central role in the relationship between companies can be identified through data analysis. We also found the strong relationship between the foreign shareholder ratio and the outside directors through empirical analysis. Furthermore, we analyzed Reuters News, which is one of the most widely used news in asset management practices using neural language models, and found that there is a close relationship between news about corporate activities and asset prices.
