Meaning & Usage
The Japanese grammar pattern 「最中に」 (saichū ni) describes an event that happens right in the middle of another ongoing action, event, or state. It carries a strong nuance that this secondary event often occurs unexpectedly, inconveniently, or at a critical juncture of the primary situation. This isn't just about two things happening simultaneously.
Instead, 「最中に」 emphasizes that one event interrupted, intruded upon, or significantly coincided with the peak or a crucial phase of another. Imagine being completely absorbed in an activity, or an event being fully underway, when something else abruptly takes place. This often suggests the timing was inopportune or surprising.
For instance, if you say 「会議の最中に電話がかかってきた」 (kaigi no saichū ni denwa ga kakatte kita), it means "A phone call came in the middle of the meeting." This strongly implies the call was an interruption to the ongoing discussion.
In English, you can translate 「最中に」 in various ways, such as "in the middle of," "right in the midst of," "at the height of," "during," or "while (something was happening)." The key distinction from simpler expressions like 「～時に」 (toki ni - when) or 「～間に」 (aida ni - while/during) is its emphasis on the intensity or critical nature of the moment. 「最中に」 suggests the ongoing activity was at its peak or a particularly crucial stage when the secondary event transpired. It highlights a specific, often unwelcome, intervention into an ongoing flow.
You'll find 「最中に」 used in both spoken and written Japanese. While not overly formal, it conveys a slightly more deliberate tone than casual phrases. It's particularly effective for narrating stories where an interruption or an unexpected occurrence is a key part of the plot. Visualize an ongoing activity as a continuous line; 「最中に」 marks a point where another event abruptly crosses or intersects that line, often causing disruption or adding a dramatic layer.
Structure & Formation
Attaching 「最中に」 to other words is quite simple, primarily connecting with nouns and verbs in the progressive -ている form.
| Word Type | Pattern | Example | Meaning |
|---|---|---|---|
| Noun | Noun + の + 最中に | 食事の最中に | In the middle of eating / dinner |
| Verb | Verb (てい)る + 最中に | 話している最中に | In the middle of talking |
| Verb
(plain form/dictionary form) | Verb (plain/dictionary) + 最中に
(Less common, often for events or with specific verbs) | 試験を行う最中に | In the middle of conducting an exam |
Detailed Explanation of Structures:
1. Noun + の + 最中に:
This is a very common and flexible pattern. You simply attach 「の」 to a noun representing an ongoing event, activity, or state, then add 「最中に」. This structure is typically used when the ongoing activity is an event or a period of time that can be clearly defined by a noun.
例: 会議の最中に (会議 no saichū ni) - In the middle of the meeting
例: 授業の最中に (授業 no saichū ni) - In the middle of class
例: 食事の最中に (食事 no saichū ni) - In the middle of a meal
2. Verb (てい)る + 最中に:
Use this when you want to specify an ongoing action performed by a person or thing. The progressive -ている form clearly indicates that the action is currently in progress. This is the most common way to connect verbs with 「最中に」.
例: 歩いている最中に (歩iteiru saichū ni) - In the middle of walking
例: 話している最中に (話shiteiru saichū ni) - In the middle of talking
例: 寝ている最中に (寝teiru saichū ni) - In the middle of sleeping
3. Verb (Plain Form / Dictionary Form) + 最中に:
While less common than the -ている form for individual actions, this structure can be used. It's often for events or planned actions, rather than continuous personal activities. Its meaning can sometimes overlap with the noun form if the verb can be nominalized. For example, 「発表する最中に」 (happyou suru saichū ni) means "in the middle of presenting." However, 「発表の最中に」 is often preferred in such cases.

Common Mistakes
Mistake 1: Using 「最中に」 for neutral "during" or "while" without emphasis on interruption.
❌ 映画の最中にポップコーンを食べた。
(This implies a strange or unexpected event during the movie, which might not be the intent.)
✅ 映画を見ている間にポップコーンを食べた。
✅ 映画を見ている時にポップコーンを食べた。
Explanation: 「最中に」 emphasizes an interruption or something unexpected/inconvenient happening at a key moment. If you simply mean something happened concurrently without that specific nuance, 「～間に」 or 「～時に」 are more natural. Eating popcorn during a movie is a normal activity, not an interruption.
Mistake 2: Attaching to past tense verbs or non-continuous actions.
❌ 食べた最中に電話が鳴った。
(The action of "eating" is not ongoing.)
✅ 食べている最中に電話が鳴った。
Explanation: The primary action must be ongoing when using 「最中に」. For verbs, this almost always means using the -ている form (progressive aspect). If the action has already finished or is not continuous, 「最中に」 cannot be used.
Mistake 3: Overuse in situations where a simpler expression would suffice.
❌ 仕事の最中に休憩した。
(Sounds a bit dramatic for a simple break.)
✅ 仕事の合間に休憩した。
✅ 仕事の途中で休憩した。
Explanation: While technically not incorrect, using 「最中に」 for routine or expected pauses within an activity can sound overly formal. It might imply a stronger interruption than intended. Phrases like 「～の合間に」 (aida ni - during breaks) or 「～の途中で」 (tochū de - in the middle of/on the way) are often more natural for planned or non-disruptive breaks.
Mistake 4: Confusing with 「～ところ」 (tokoro).
❌ 今出かける最中です。
(While understandable, it's not the most natural expression for "just about to leave.")
✅ 今出かけるところです。
Explanation: 「～ところ」 precisely indicates the stage of an action: just before (Verb-る + ところ), currently happening (Verb-ている + ところ), or just after (Verb-た + ところ). While 「Verb-ているところ」 can sometimes mean "in the middle of doing something," similar to 「Verb-ている最中に」, 「ところ」 focuses on the phase of the action itself. In contrast, 「最中に」 emphasizes the timing of an external event interrupting or coinciding with that ongoing action.
Cultural Notes
In Japanese culture, maintaining flow and uninterrupted activity, especially in formal settings like meetings or ceremonies, is often highly valued. Therefore, an unexpected event occurring 「最中に」 can convey a greater sense of disruption or inconvenience than it might in some other cultures.
When a Japanese person uses 「最中に」, they are often subtly highlighting this aspect of untimeliness or the impact of the interruption. For instance, if someone says 「食事の最中に来客があった」 (shokuji no saichū ni raikyaku ga atta - a guest arrived in the middle of dinner), it often implies the host had to stop their meal and attend to the guest, which could be a minor inconvenience, even if the guest was welcome. The phrase subtly conveys that the timing wasn't ideal.
「最中に」 also serves to describe moments of high tension or importance. For example, in a sports commentary, 「試合の最中に選手が交代した」 (shiai no saichū ni senshu ga kōtai shita - a player was substituted in the middle of the game) might suggest a crucial tactical change made during an intense phase of the match. Choosing 「最中に」 over a neutral 「～時に」 or 「～間に」 underscores the significance of the substitution's timing.
In everyday conversation, it's a useful expression for adding a touch of drama or emphasis when recounting a story about something that happened at an awkward or important moment. It allows the speaker to convey not just when something happened, but also the significant circumstances surrounding its occurrence.

JLPT Tips
When you see 「最中に」 in the JLPT N3 exam, pay close attention to the context and the accompanying verbs/nouns. Remember its core nuance: an event or action occurring in the middle of another ongoing, often important or intense, activity, usually implying an interruption or an unexpected coincidence.
1. Identify the ongoing event: Look for the noun or the Verb-ている form that precedes 「最中に」. This will tell you what the primary, ongoing activity is.
2. Understand the consequence: The sentence following 「最中に」 will describe what happened. Consider if this secondary event is a normal occurrence, an interruption, or something surprising. If it's a neutral or expected event, 「最中に」 might not be the most appropriate choice in a multiple-choice question; options like 「～間に」 or 「～時に」 might fit better.
3. Distinguish from similar grammar: JLPT frequently tests your ability to differentiate between similar-sounding grammar points.
- 「最中に」: emphasizes an interruption or critical timing within an ongoing activity.
- 「間に」: simply states an occurrence within a duration.
- 「うちに」: highlights taking action before a state changes.
- 「ところ」: specifies the stage of an action (just before, during, just after).
4. Look for context clues: Words like 「急に」 (kyū ni - suddenly), 「突然」 (totsuzen - abruptly), or verbs that imply disruption (e.g., 「鳴り出す」 - to start ringing, 「割り込む」 - to cut in) are strong indicators that 「最中に」 is the correct grammar point.
5. Practice with different sentence patterns: Ensure you are comfortable with both the Noun + の + 最中に and Verb-ている + 最中に patterns. Knowing which types of words can precede 「最中に」 will help you quickly eliminate incorrect options.
