Kufu is a source of imagination and creativity; to know how to master Kufu means to
know how to educate students and engineers to be creative. However, Suzuki says that
unfortunately no teaching and no methods can help to master the secrets of kufu, because
technique is secondary in mastering kufu and each student and engineer must struggle to
develop his or her own kufu from within. Once they have mastered their own kufu in
engineering, they become masters of engineering. This is exactly why Professor Emori
said in his famous book in Scale Modeling [7], “professional intuition is the best tool in
engineering.” Taiichi Ohno, one of the fathers of the Toyota Production System, reminds
us that “If you look up the word ‘engineer’ in an English dictionary, you might find
‘technologist,’ while in Japanese, its meaning uses the character for ‘art.”[9] A schematic
showing characteristics of Eastern culture on which professional intuition is based, is
shown in Fig. 3, in comparison to characteristics of Western culture on which scientific
methods are based.
