儀礼

The word "girei" encompasses both the physical act of a ceremony and the abstract rules of social or diplomatic conduct. While "gishiki" (儀式) refers primarily to the event or ritual itself, "girei" emphasizes the prescribed form, the rules, and the etiquette associated with that event.

In a social or political context, it is often used as a translation for "protocol." It refers to the strict adherence to formal behavior to maintain harmony and respect, especially in international diplomacy or high-level official interactions.

In everyday modern Japanese, "girei" can sometimes carry a nuance of being "mere formality" or "perfunctory." When someone describes an action as "gireiteki" (儀礼的), it often implies that the action is performed out of obligation or social convention rather than genuine feeling or necessity.
