Since time immemorial, before C.G. Jung named the phenomenon, synchronicity has been perceived by people of various cultures. In the modern Western world view, mind and matter are clearly separated. Synchronistic phenomena, which cross the boundary between and connect these two distinct categories of reality, are therefore intriguing. However, in places where older world views have been retained in some way, such as in Japan, people seem to be less curious than Westerners about why and how synchronistic events happen; they seem to think of them more as natural occurrences—“just so” and “it happens.” I will approach synchronicity from these perspectives, using the Japanese psyche as an example, to explore its nature.
