かと思いきや【かとおもいきや】

かと思いきや is used to express that something turned out contrary to what was expected. The speaker describes a situation or assumption in the first clause, then reveals in the second clause that reality was completely different. It carries a strong sense of surprise at the unexpected outcome.

It can be translated as "just when I thought…", "or so I thought, but…", or "contrary to expectations…".

The structure attaches to the end of a clause that describes what was expected or assumed:

Usage notes

• The first clause represents the assumed or expected situation, while the second clause states the actual (surprising) outcome.
• Both clauses can be in the past or present tense, but the pattern is most common when narrating past events.
• The verb or adjective before かとおもいき思いきや is typically in plain form (dictionary form or た-form).

Nuance

This expression is somewhat literary or narrative in tone. It is used in written Japanese, storytelling, news commentary, and dramatic spoken recounting of events. It is less common in casual everyday conversation, where simpler expressions like 〜～とおもったら思ったら might be preferred.

Compared to 〜～とおもったら思ったら, かと思いきや places stronger emphasis on the contrast between expectation and reality, and often sounds more dramatic or emphatic.
