arrival of an opportunity; having a chance
Used when a favorable opportunity presents itself, often with a sense of seizing the moment. Common in motivational or business contexts.
The opportunity has arrived! Let's act now.
Seeing that a chance had come, he immediately volunteered.
Compound of チャンス (chance, from English) and 到来 (arrival, from Chinese-derived elements). The exact origin as a set phrase is uncertain, but it likely emerged in modern Japanese as a natural combination.
