syusaisya ga sanpokoosu wo kakuninsuru.

It is read:

主催者が散歩コースを確認する。
しゅさいしゃ が さんぽコース を かくにんする。

Word by word:

• 主催者 = しゅさいしゃ = organizer
• 散歩コース = さんぽコース = walking route / walking course
• 確認する = かくにんする = to check / confirm

In normal Japanese writing, spaces are usually not used, so it would normally appear as:

主催者が散歩コースを確認する。

が marks the grammatical subject of the sentence.

So in this sentence:

• 主催者が = the organizer is the one doing the action
• 散歩コースを = the walking route is what is being checked
• 確認する = checks / will check

A learner often compares が and は here.

• が focuses more directly on who does the action
• は would mark 主催者 as the topic

So:

• 主催者が散歩コースを確認する。 = The organizer checks the walking route.
• 主催者は散歩コースを確認する。 = As for the organizer, they check the walking route.

Both can be correct, but が is a very natural choice when simply identifying the subject.

を marks the direct object, meaning the thing directly affected by the verb.

Here:

• 散歩コースを確認する = check the walking route

So 散歩コース is the thing being checked, and を shows that relationship.

This is very common in Japanese:

• 本を読む = read a book
• ドアを開ける = open the door
• 道を確認する = check the route/road

Not exactly. 確認する means to confirm, to check, or to make sure of something.

It is more deliberate than just seeing something.

Compare:

• 見る = to look at / to see
• 確認する = to check and confirm that something is correct, safe, ready, or understood

So 散歩コースを確認する suggests something like:

• checking the route beforehand
• confirming the route details
• making sure the walking course is correct or suitable

It sounds more careful and purposeful than simply looking at the route.

確認する is the plain, dictionary form of the verb.

This form can be used:

• in dictionaries
• in casual speech
• in written explanations
• for non-past meaning

Non-past in Japanese can mean:

• present habitual: checks
• future: will check

So depending on context, this sentence could mean:

• The organizer checks the walking route.
• The organizer will check the walking route.

If you wanted a polite version, you would say:

• 主催者が散歩コースを確認します。

Japanese often does not mark singular vs. plural unless it is important.

So 主催者 can mean:

• the organizer
• organizers

The exact meaning depends on context.

The same is true for English articles:

• Japanese does not automatically show a, the, or plural -s

So 主催者が散歩コースを確認する。 could refer to:

• one specific organizer
• organizers in general
• the organizer of an event

Context tells you which is intended.

Yes, it is understandable and natural.

散歩コース literally means:

• walking course
• walking route

It refers to a route for walking, often for leisure, exercise, or an event.

Depending on context, other expressions might also be used, such as:

• 散歩道 = walking path
• ルート = route
• コース = course

But 散歩コース is perfectly reasonable if the intended meaning is a planned walking route.

Yes, Japanese word order is more flexible than English, because particles show each word’s role.

The most basic order here is:

主催者が 散歩コースを 確認する。
subject + object + verb

This is the most neutral and natural order.

You may sometimes see changes for emphasis, such as:

• 散歩コースを主催者が確認する。

This could put more focus on the walking route.

However, the verb usually comes at the end in a normal Japanese sentence, so 確認する stays at the end.

No, standard Japanese normally does not use spaces between words.

So the usual written form is:

主催者が散歩コースを確認する。

Spaces are often added in learning materials to make the structure easier to see:

• 主催者 / が / 散歩コース / を / 確認する

This helps beginners identify:

• nouns
• particles
• the verb

But in real Japanese writing, you should expect no spaces.

Usually, yes. 主催者 most often means organizer, especially the person or group in charge of an event, activity, or program.

Examples:

• イベントの主催者 = the organizer of an event
• 大会の主催者 = the organizer of a tournament

So in this sentence, it sounds like someone responsible for planning or running something is checking the walking route.

If you meant a guide, leader, or staff member specifically, Japanese might use a different word depending on the situation.

Yes. Since Japanese leaves some things unstated, several English translations are possible.

Possible translations include:

• The organizer checks the walking route.
• The organizer will check the walking route.
• The event organizer confirms the walking course.
• The organizers check the walking route.

The core meaning stays the same:

• 主催者 = the person/people organizing
• 散歩コース = the route/course for walking
• 確認する = check/confirm

The exact English wording depends on context and style.
