noun
unpropitious direction
A term from traditional Japanese directional astrology (九星気学 or similar systems). Refers to a direction that is considered especially inauspicious on a given day or for a given person, often associated with misfortune or accidents. Not used in everyday modern Japanese outside of fortune-telling contexts.
今日の暗剣殺は北西の方角です。
Today's unpropitious direction is the northwest.
Compound of 暗 (an, 'dark, hidden'), 剣 (ken, 'sword'), and 殺 (satsu, 'kill'). The term originates from traditional Chinese/Japanese directional astrology, where it names a specific inauspicious influence. The exact historical derivation is uncertain.
