の connects two nouns.

• 親戚 = relatives
• 集まり = gathering

So 親戚の集まり means a gathering of relatives or a relatives’ gathering.

Here, 親戚 describes what kind of gathering it is.

Not exactly.

• 家族 = family, usually your immediate family or household
• 親戚 = relatives

So 親戚 includes people like uncles, aunts, cousins, grandparents, and other extended family members. In this sentence, it specifically means a gathering with relatives, not just the people in your immediate family.

集まる is the verb to gather or to get together.

集まり is a noun form, meaning gathering or get-together.

So:

• 親戚が集まる = relatives gather
• 親戚の集まり = a gathering of relatives

In this sentence, we need a noun, because it is talking about the event itself.

で marks the place or setting where something happens.

• 集まりで = at the gathering

When は is added, it makes that setting the topic or adds a slight contrast:

• 集まりでは = as for at the gathering / at the gathering, ...

So では here helps frame the sentence as when it comes to gatherings with relatives, this is what we do or at a relatives’ gathering, ...

Using just で would also be understandable, but では sounds more like setting the scene as the topic.

まず means first or to start with.

It tells you that eating edamame is the first action in the sequence.

So the sentence structure is:

1. まず = first
2. 枝豆を食べて = eat edamame
3. それから = after that
4. 刺身や焼き鳥をゆっくり食べます = slowly eat sashimi, yakitori, and so on

Yes, both show order, but they do different jobs:

• まず = first
• それから = after that / then

Using both makes the sequence very clear and natural. It sounds like the speaker is walking you through the order of events step by step.

Without them, the sentence would still be grammatical, but it would lose some of that clear sequencing.

食べて is the て-form of 食べる.

The て-form is often used to connect actions. In this sentence, it means:

• eat edamame, and then...

So:

• 枝豆を食べて、それから... = eat edamame, and after that...

This is a very common way to link actions in Japanese.

That is normal Japanese sentence structure.

The earlier verb, 食べて, is in て-form because it connects to the next action. The final verb, 食べます, carries the main tense and politeness for the sentence.

So the pattern is:

• connected action: 食べて
• final action: 食べます

This is similar to saying:

• I eat edamame, and then I eat sashimi and yakitori slowly.

Only the last verb is fully finished in polite form.

This is a very common learner question.

• と means and, and usually gives a complete list
• や means things like ... and ..., so it gives examples and suggests the list is not complete

So:

• 刺身と焼き鳥 = sashimi and yakitori
• 刺身や焼き鳥 = things like sashimi and yakitori

In this sentence, や makes it sound like these are typical foods eaten at the gathering, but maybe not the only ones.

Yes, grammatically ゆっくり is placed right before the second 食べます, so it most directly modifies that action:

• 刺身や焼き鳥をゆっくり食べます = eat sashimi and yakitori slowly

However, in overall meaning, it can also give the feeling that after starting with edamame, the meal continues at a relaxed pace. Still, its clearest grammatical connection is to the second eating action.

Because there are two separate eating actions, and each one has its own direct object.

• 枝豆を食べて = eat edamame
• 刺身や焼き鳥を食べます = eat sashimi and yakitori

Each を marks what is being eaten.

Japanese nouns usually do not show singular/plural the way English does.

So 枝豆 could mean:

• edamame
• some edamame
• edamame beans

The same is true for 刺身 and 焼き鳥 in many contexts. The exact number is understood from context, not from the noun form itself.

It can cover both, depending on context.

Japanese non-past forms like 食べます can mean:

• a habitual action
• a future action
• a general statement

In this sentence, it most naturally sounds like either:

• a habitual/customary action at relatives’ gatherings, or
• a description of what will happen at such a gathering

Context tells you which one is intended.

It is polite, but not extremely formal.

The verb ending -ます in 食べます makes it polite and appropriate for normal conversation, explanations, or speaking to someone you do not know very well.

A casual version might be:

• 親戚の集まりでは、まず枝豆を食べて、それから刺身や焼き鳥をゆっくり食べる。

So the original sentence is a standard polite style.

Here are the main readings:

• 親戚 = しんせき
• 集まり = あつまり
• 枝豆 = えだまめ
• 刺身 = さしみ
• 焼き鳥 = やきとり
• 食べて = たべて
• 食べます = たべます

These are all very common words, especially 枝豆, 刺身, and 焼き鳥 when talking about food.
