kekkyoku kare ha ziyuuseki wo eranda.

結局 means something like in the end, eventually, or after all.

In this sentence, it shows the final result after some kind of consideration, hesitation, or change of plans. So the nuance is not just that he chose an unreserved seat, but that this was the outcome at the end.

For example, it can imply:

• he was deciding between options
• something happened first
• this was the final choice

So 結局 彼は自由席を選んだ feels like In the end, he chose an unreserved seat.

は marks 彼 as the topic of the sentence.

So 彼は means something like:

• as for him
• he, speaking about him as the topic

This is very common when the speaker is talking about someone already known in the conversation.

If you used が instead, the sentence would sound more like you are specifically identifying him as the one who chose it, possibly in contrast to someone else.

Compare:

• 彼は自由席を選んだ。 = As for him, he chose an unreserved seat.
• 彼が自由席を選んだ。 = He is the one who chose an unreserved seat.

So in your sentence, は is the more neutral, topic-based choice.

自由席 is a set expression meaning unreserved seat or non-reserved seating.

It is especially common in contexts like:

• trains
• shinkansen
• buses
• theaters or venues with non-assigned seating

It does not mean a seat that is free in the sense of costing no money. Here 自由 means something like open choice / not fixed, and 席 means seat.

So 自由席を選んだ means he chose the unreserved seating option.

を marks the direct object of the verb.

The verb here is 選んだ from 選ぶ, which means to choose. The thing being chosen is 自由席, so it takes を.

Structure:

• 彼は = topic
• 自由席を = the thing chosen
• 選んだ = chose

So 自由席を選んだ literally means chose an unreserved seat.

The dictionary form is 選ぶ, meaning to choose.

選んだ is the plain past form.

This happens because 選ぶ is a godan verb ending in -ぶ. For these verbs, the past tense changes like this:

• ぶ → んだ

So:

• 選ぶ → 選んだ

Other similar examples:

• 遊ぶ → 遊んだ
• 呼ぶ → 呼んだ

So 選んだ means chose.

Japanese normally puts the main verb at the end of the clause.

That is one of the most basic differences from English.

English:

• He chose an unreserved seat in the end.

Japanese:

• 結局 彼は 自由席を 選んだ。

A rough structural breakdown is:

• 結局 = in the end
• 彼は = as for him
• 自由席を = unreserved seat
• 選んだ = chose

So Japanese often follows a topic/object/verb pattern, with the verb coming last.

Yes, to some extent.

Because particles show each word’s role, Japanese word order is more flexible than English word order. For example, these are all possible:

• 結局 彼は 自由席を 選んだ。
• 彼は 結局 自由席を 選んだ。
• 彼は 自由席を 結局 選んだ。

They all basically mean the same thing, but the emphasis and naturalness can shift slightly.

The original sentence is very natural. Putting 結局 near the beginning is especially common, because it sets the overall tone right away: in the end...

No. This is a very common question for English speakers.

In Japanese, pronouns like 彼 are used less often than English he. If the subject is already clear from context, Japanese often leaves it out completely.

So in real conversation, you might also hear:

• 結局、自由席を選んだ。

If everyone already knows who is being talked about, there is no need to say 彼.

Using 彼 is not wrong at all, but Japanese often prefers omission when the meaning is obvious.

Not usually. That would be a misunderstanding.

Even though 自由 often means freedom or free, the compound 自由席 is a fixed term meaning unreserved seat.

So it does not mean:

• a seat that costs nothing
• any seat that happens to be empty

It means a seating category where the seat is not assigned in advance.

This is a good example of why it helps to learn compounds as whole vocabulary items, not only by combining each character’s basic meaning.

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

So 自由席を選んだ could be translated depending on context as:

• chose an unreserved seat
• chose the unreserved seat option
• went with non-reserved seating

English requires an article, but Japanese does not. The exact English wording depends on the situation.

This is normal, and learners should avoid trying to find a hidden the or a in every Japanese noun phrase.

Yes, absolutely.

In many real situations, 自由席を選んだ does not mean he pointed at one specific chair and chose it. It often means he chose the category or option of unreserved seating.

For example:

• on a train ticket screen
• when deciding between reserved and non-reserved seating
• when buying a ticket

So depending on context, natural English could be:

• In the end, he chose an unreserved seat.
• In the end, he chose non-reserved seating.
• In the end, he went with the unreserved option.

A simple way to understand it is:

• 結局 = adverbial expression: in the end
• 彼は = topic: as for him
• 自由席を = direct object: unreserved seat / unreserved seating
• 選んだ = verb in plain past: chose

So the pattern is:

[time/result expression] + [topic は] + [object を] + [verb]

That gives:

結局 彼は 自由席を 選んだ。

Once you get used to this pattern, many similar Japanese sentences become much easier to read.
