を機に

を機に expresses that something happens or changes after a certain event or moment is reached. It marks using that moment as a turning point or motivation to start a new course of action. It is often used for personal decisions, shifts in plans, or turning points in life, avoiding a mere description of the prior event. Typical contexts include business decisions, personal life changes, or social initiatives triggered by a specific occurrence. Example sentences can illustrate different nuances: この景気を機に社員の福利厚生を見直す。Taking this economic upturn as an opportunity to review employee welfare. この機会を機に英語を本格的に勉強する。Taking this opportunity to study English seriously. 子どもが独立したを機に引っ越しを決意した。I decided to move, using my child’s independence as a turning point. 被災地を機に地域の絆が深まった。The disaster-affected area became a turning point for stronger community ties.
