動物保護施設の譲渡会に参加する。 is read:

どうぶつほごしせつ の じょうとかい に さんかする。

In romaji:

dōbutsu hogo shisetsu no jōtokai ni sanka suru

It is a compound noun made of three parts:

• 動物 = animal
• 保護 = protection, rescue
• 施設 = facility

So literally it means animal protection facility. In natural English, this is often something like animal shelter or animal rescue center.

譲渡会 is also a compound noun:

• 譲渡 = transfer, handing over
• 会 = meeting, gathering, event

In the context of animal rescue, 譲渡 usually refers to placing an animal with a new owner. So 譲渡会 means an adoption event, adoption fair, or pet adoption event.

Here, の connects two nouns.

It shows that the 譲渡会 is related to the 動物保護施設. Depending on context, that can mean:

• the event is organized by the animal shelter
• the event belongs to the animal shelter
• the event is held by or associated with the animal shelter

So 動物保護施設の譲渡会 means something like:

• the animal shelter’s adoption event
• an adoption event at/by an animal protection facility

Because 参加する normally takes に to mark the event, activity, or group that someone joins.

For example:

• 会議に参加する = participate in a meeting
• パーティーに参加する = participate in a party
• 譲渡会に参加する = participate in an adoption event

So に marks what you are participating in.

行く simply means to go.

参加する means to participate, to take part, or often to attend as a participant.

So this sentence is not just saying that someone goes to the place. It says that they are joining the event.

That can sound a little more involved than go, although in Japanese it is very normal to use 参加する for attending events.

No, not by itself.

参加する only tells you that the person is participating in or attending the adoption event. It does not specifically say they adopt an animal.

They could be:

• a potential adopter
• a volunteer
• a staff member
• a visitor

If you wanted to clearly say that someone actually adopted an animal, you would need different wording.

Yes. Japanese often leaves out the subject when it is clear from context.

So this sentence could mean:

• I participate in the animal shelter’s adoption event
• We participate in the animal shelter’s adoption event
• Someone participates in the animal shelter’s adoption event

The subject is understood from the situation, not stated directly.

Japanese normally places the main verb at the end.

So the structure is:

• 動物保護施設の譲渡会 = the animal shelter’s adoption event
• に = marking the thing being joined
• 参加する = participate

A very literal English-style breakdown would be:

animal shelter’s adoption event + in + participate

But natural English rearranges this as:

participate in the animal shelter’s adoption event

参加する is the plain form, also called the dictionary form.

It can be used in:

• casual speech
• written explanations
• headlines
• dictionary-style example sentences

参加します is the polite form.

So the difference is mainly style:

• 譲渡会に参加する。 = plain
• 譲渡会に参加します。 = polite

Both are grammatically correct.

The plain non-past form 参加する can refer to:

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

So depending on context, it could mean:

• participate in the animal shelter’s adoption event
• will participate in the animal shelter’s adoption event
• participates in the animal shelter’s adoption event

Japanese often leaves the exact time to context unless it needs to be stated clearly.

Japanese does not use articles like English a/an and the.

So 動物保護施設の譲渡会 could be translated in different ways depending on context:

• the animal shelter’s adoption event
• an animal shelter adoption event
• the adoption event at the animal shelter

The Japanese expression stays the same, and English adds the article that sounds most natural in context.
