Overview
The five senses (五感, gokan) that play a key role in the way humans respond to stimuli from the outside world are:
Basically, they are the organs that allow an organism to perceive the outside world, and if all of them were lost, the organism would not be able to perceive any existence other than its own.
In addition, the five senses do not develop equally, but often develop in individual ways, such as being strong or weak, depending on a variety of factors.
Incidentally, since organisms have a self-complementary function that attempts to compensate for deficiencies, the long-term loss of one of the senses for any reason will lead to greater than normal development of one of the other senses or all senses other than the one that has been lost.
The five senses have a strong influence on the development of cranial nerves, and the amount of constant stimulation of any one sense during childhood can determine the direction of so-called talents and influence future personality.
