Kijima's research interests are in systems-science-based approach to decision making and information. In particular, recently, he proposed a new paradigm called "poly-agent systems". It tries to deal with complexity involved in decision situations consisting of plural and autonomous decision makers. He is interested in integrating what we call hard and soft systems approaches to decision-making and management, by advocating Decision Systems Sciences. In 2006 he received a major grant from the government on agent-based modelling and systems research.
