kaigi de mondai ga hasseisita.

Here, で marks the location or setting where something happens.

So 会議で means at the meeting or in the meeting.

In this sentence, it tells you the context in which the problem occurred:

• 会議で = at the meeting
• 問題が発生した = a problem occurred

This use of で is very common for places or events where an action or event happens:

• 学校で勉強する = study at school
• 会議で話す = speak at a meeting

が marks 問題 as the thing that occurred.

So:

• 問題が = the problem / a problem (as the subject of the event)
• 発生した = occurred / arose

With verbs like 発生する, 起こる, and ある, が is often used to mark what exists or happens.

In other words, the sentence is structured like:

• As for what happened? A problem occurred.

Using を would not work here, because 発生する is not something you normally do to a problem. The problem itself is what comes into existence or happens.

発生した is the past form of 発生する.

• 発生する = to occur, to arise, to break out, to happen
• 発生した = occurred, arose, happened

This verb is often used in somewhat formal or objective contexts, such as:

• problems
• accidents
• system errors
• natural phenomena

So 問題が発生した sounds a bit more formal than simply saying 問題が起きた.

It comes from the noun-like Sino-Japanese word 発生 plus する, which makes it a verb.

Step by step:

• 発生する = to occur
• past tense of する = した
• so 発生した = occurred

This is a very common pattern in Japanese:

• 勉強する → 勉強した
• 連絡する → 連絡した
• 発生する → 発生した

These are often called suru-verbs.

It is read:

かいぎ で もんだい が はっせいした。

Breakdown:

• 会議 = かいぎ
• で = で
• 問題 = もんだい
• が = が
• 発生した = はっせいした

A natural pronunciation would flow together smoothly: かいぎでもんだいがはっせいした。

Japanese often leaves out information that is obvious or unnecessary.

In this sentence, the important thing is not who caused the problem, but simply that a problem occurred during the meeting.

Japanese frequently focuses on the event itself:

• 問題が発生した = a problem occurred

If the speaker wanted to say who caused it, they would need to add more information. But as it stands, the sentence is neutral and event-focused.

Yes, Japanese word order is more flexible than English, as long as the particles stay clear.

The most neutral order is:

• 会議で問題が発生した。

But you might also hear:

• 問題が会議で発生した。

That said, the original version sounds more natural if the speaker wants to set the scene first:

• At the meeting, a problem occurred.

In Japanese, particles like で and が are what show the grammatical roles, so the order is not as fixed as in English.

Both can mean happened or occurred, but the nuance is different.

• 問題が起きた = a problem happened
• 問題が発生した = a problem occurred

発生した sounds:

• more formal
• more technical
• more objective
• common in reports, business, news, and system descriptions

起きた sounds:

• more everyday
• more conversational
• less formal

So in a business-like sentence involving a meeting, 発生した sounds very natural.

In this sentence, it most naturally means at the meeting or during the meeting.

That is because で commonly marks the place or setting where something happens.

If you wanted to clearly say because of the meeting, Japanese would usually use a different expression, such as:

• 会議のせいで
• 会議があったため
• 会議によって in some contexts

So here, 会議で問題が発生した is understood as: A problem occurred during the meeting.

Japanese does not have articles like a, an, or the.

So 問題 by itself can mean:

• a problem
• the problem
• problems

The exact meaning depends on context.

In this sentence, without extra context, English usually translates it as:

• A problem occurred at the meeting.

But in the right context, it could also be:

• The problem occurred at the meeting.

Japanese leaves that kind of distinction to context much more often than English does.

Yes, it sounds fairly neutral-to-formal.

Reasons:

• 発生した is a formal-sounding verb
• the sentence is short and objective
• it sounds like something from business, reporting, or documentation

In casual conversation, someone might say:

• 会議で問題が起きた。

That sounds more everyday.

So the original sentence is natural in:

• business Japanese
• reports
• meeting summaries
• news-like descriptions
