sanpokoosu no syuppatutiten wo kakuninsuru.

It can function as a complete sentence in Japanese, but in many contexts it sounds like an instruction, checklist item, or heading.

• 確認する is the plain/dictionary form: to check / to confirm
• Because of that, the whole phrase can feel like:
  • Check the starting point of the walking route
  • To confirm the starting point of the walking course
• In manuals, schedules, apps, and bullet points, Japanese often uses the dictionary form this way.

In everyday conversation, you might more often see:

• 散歩コースの出発地点を確認します。 = I will check the starting point...
• 散歩コースの出発地点を確認してください。 = Please check the starting point...

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

So this sentence does not explicitly say:

• I check...
• You should check...
• We are checking...

The listener or reader understands the missing subject from the situation.

For example:

• In a manual, it might mean Check the starting point
• In a report, it might mean We confirm the starting point
• In a plan, it might mean To confirm the starting point

This is extremely normal in Japanese.

散歩 means walk or stroll, and コース means course, route, or path.

So 散歩コース means something like:

• walking route
• strolling course
• walk path

In natural English, walking route is often the best choice.

A lot of Japanese compounds work like this:

• noun + noun
• here, 散歩 describes what kind of コース it is

So 散歩コース is simply a route for walking.

The particle の connects nouns and shows that the second noun belongs to, relates to, or is specified by the first noun.

So:

• 散歩コース = walking route
• 出発地点 = starting point
• 散歩コースの出発地点 = the starting point of the walking route

You can think of の here as similar to:

• of
• sometimes an apostrophe 's
• or just a noun modifier in English

Other examples:

• 学校の先生 = the teacher of the school / the school’s teacher
• 旅行の計画 = the travel plan / plan for the trip

In this sentence, の links walking route and starting point.

を marks the direct object of the verb.

The verb is 確認する = to check / confirm

What is being checked?

散歩コースの出発地点 = the starting point of the walking route

So:

• 散歩コースの出発地点を確認する
• Check/confirm the starting point of the walking route

This is a very common pattern:

• 予定を確認する = check the schedule
• 名前を確認する = confirm the name
• 地図を確認する = check the map

Also, remember that を is usually pronounced o, even though it is written を.

出発地点 is a compound noun made of:

• 出発 = departure, starting out
• 地点 = point, spot, location

So together it means:

• starting point
• point of departure
• departure point

This kind of noun compound is very common in Japanese. Instead of using a long phrase, Japanese often combines nouns into one compact word.

Compare:

• 出発地点 = starting point
• 到着地点 = arrival point
• 中間地点 = midpoint

Good question. Both can refer to a place, but they have different feels.

• 場所 = place, location
  
  • broader and more general
• 地点 = point, spot, location
  
  • more specific, technical, map-like, or precise

So:

• 出発場所 = starting place
• 出発地点 = starting point

In a route, course, map, or navigation context, 地点 sounds especially natural because it suggests a specific point on the route.

It can mean both, depending on context.

Common English translations:

• check
• confirm
• verify

The nuance of 確認する is usually:

• look at something carefully
• make sure it is correct
• make sure you understand or know it

So in this sentence, it could mean:

• Check the starting point of the walking route
• Confirm the starting point of the walking route

In many everyday situations, check is the most natural English translation.

You are right: normal Japanese writing usually does not use spaces between words.

So the standard writing would be:

散歩コースの出発地点を確認する。

If you see spaces, they are often added:

• for learners
• in teaching materials
• to make the structure easier to see
• sometimes in captions or design layouts

So the spaces are just a reading aid, not standard spelling.

By itself, 散歩コースの出発地点を確認する sounds a little like a written note, task, or heading.

In spoken Japanese, you might hear:

• 散歩コースの出発地点を確認します。
  = I’ll check the starting point of the walking route.

• 散歩コースの出発地点を確認してください。
  = Please check the starting point of the walking route.

• 散歩コースの出発地点を確認しよう。
  = Let’s check the starting point of the walking route.

So the original form is natural, but it sounds more written or list-like than conversational.

A natural reading is:

さんぽコース の しゅっぱつちてん を かくにんする

Breakdown:

• 散歩 = さんぽ
• コース = コース
• の = no
• 出発地点 = しゅっぱつちてん
• を = o
• 確認する = かくにんする

A couple of pronunciation notes:

• 出発 has a small っ in しゅっぱつ
• を is pronounced o
• コース has a long vowel sound: kōsu or koosu depending on how you think of it

So the whole thing sounds roughly like:

sanpo kōsu no shuppatsu chiten o kakunin suru
