Eshaku (会釈 - Bow/Nod)

Japanese people often do an act called 会釈 (eshaku), when they pass/meet their boss or acquaintance.

"Eshaku" refers to bow or nod that is done to express your familiarity, favor, or appreciation to others.

This word is short for 和会通釈 (waetsūshaku), the Buddhist terminology, which originally meant "to compare two doctrines that sound contradictory each other and reveal the underlying true significance."

This came to mean "to behave by considering others' hearts," and now it has come to mean bow or nod.

Incidentally, it is said that the rough standard angle of your upper body when you do "eshaku" is fifteen degrees.
