Origin

Derived from the physical reality that the 'front' and 'back' of an object constitute a single body. Since it is impossible to separate one side from the other, the term came to be used for abstract concepts, human relationships, and social phenomena where two elements are inseparably linked.

📖Literary Usage

In Nishida Kitaro's 'An Inquiry into the Good' (Zen no Kenkyu), this term is used in philosophical discussions regarding how subject and object, or intellect and will, are 'hyouri ittai' (two sides of the same coin).
