About を契機に

を契機(けいき)に is a grammar construction made up of を, the noun 契機(けいき) 'chance' or 'trigger' and に. It is a formal pattern that is used to indicate some sort of trigger and may be translated '(A) led to (B)', 'as an opportunity to (A), (B)', or 'as a result of (A), (B)'. (A) may either be a positive or negative event, but will usually be something extremely big in terms of life, or current/historical events in the world.

を契機(けいき)に will be seen after nouns, or verbs that have been nominalized with either の or こと.

Alternatively, にして or として may replace に without any change in the overall meaning.

Caution

Unlike をきっかけに, を契機(けいき)に will almost exclusively be used in relation to some turning point or critical juncture. Due to this, it can sound quite unnatural when used to express a trigger that would not be considered a big event.

What is the difference between を契機に and をきっかけ?
wrt7MameLZE33wlmpCAV
The details for this grammar point indicate it can be written ～にして・として, but none of the examples show this usage and both are simply marked wrong. Under what circumstances are these variations used?

Hey @Hadros232232 !

を契機に is usually used in writing, or when the speaker is talking about social issues or historical topics, but きっかけに is usually used when talking about yourself.
