Seeking a realistic way of individual decision making

In this paper, we try to introduce a realistic way of individual decision making based on the Japanese way of thinking, which may make up for the defect of today's popular decision-making methods that heavily depend on the logic of the Western way of thinking, typically shown in Arrow's impossibility theorem. The presented way of individual decision making is realistic because it follows people's actual choice procedure; it is also a promising way in the reconsideration of Arrow's framework and the result from a different direction. We compare the Western and the Japanese ways of thinking in detail in this paper because the sharp difference between them is expected to give the reader new hints for the creative development of decision-making methods.
