最中に — Right in the Thick of It
Expresses that something happens right in the middle of an ongoing action or event — usually an interruption at the most inconvenient or intense moment. It carries a stronger 'at the very peak of' nuance than a simple 'while', so it pairs naturally with unexpected or disruptive events.
Structure
[Verb ている form] / [Noun] + の + 最中に
Examples
食事の最中に電話がかかってきた。
Shokuji no saichuu ni denwa ga kakatte kita.

会議をしている最中に、地震が起きた。
Kaigi wo shite iru saichuu ni, jishin ga okita.

試験の最中に急にお腹が痛くなった。
Shiken no saichuu ni kyuu ni onaka ga itaku natta.

の最中に highlights the worst possible timing during the exam.
• Almost always followed by a sudden, disruptive, or unwelcome event. • 最中に needs an action of some duration; it cannot mark an instantaneous moment. • Casual speech often shortens it to 〜最中 (saichuu) without に at the end of a clause.
Commonly confused with
The JLPT rarely asks whether you recognise a pattern — it asks which of several similar patterns fits. These are the ones 最中に is tested against.
vs ている間に
最中に stresses the very peak of an action and expects an interruption, while 間に neutrally marks any point within a span with no 'worst timing' nuance.
vs ところに
ところに marks the precise instant an action was about to/just happened, whereas 最中に requires the action to be actively ongoing and mid-flow.
