kanpo wo kikkake ni, mata wookinguibento ni sankasita.

It is read かんぽ.

完歩 means completing a walking course/all the way to the end on foot. It is often used for walking events, charity walks, hiking-style events, or any organized course where the goal is to finish the whole route.

A useful comparison is:

• 完歩 = complete a walking route
• 完走 = complete a race/run

So 完歩 fits especially well with ウォーキングイベント.

N を きっかけに means using N as a trigger/opportunity/turning point.

So the pattern is:

X をきっかけに、Yした。
= Triggered by X, I did Y.
= Taking X as an opportunity, I did Y.

In this sentence, completing the walk became the reason or turning point that led to participating in another walking event.

This expression often suggests that something caused a new action, habit, or change.

Because 完歩をきっかけに is a set grammar pattern.

Here, 完歩 is the thing being treated as the trigger or occasion, and the pattern uses を:

• N をきっかけに
• N をきっかけとして
• N をきっかけにして

So this を does not mean 完歩 is the direct object of 参加した. It belongs specifically to the きっかけ expression.

Yes. That is also natural.

You can use either:

• 完歩をきっかけに
• 完歩したのをきっかけに

The version with 完歩 treats it more compactly as a noun-like event.
The version with 完歩したの spells out the action more clearly: the fact that I completed it.

Both are grammatical, but the original sentence is concise and natural.

Here, また most naturally means again.

So the idea is that after that trigger, the speaker participated in a walking event again.

Depending on context, また can sometimes feel like also, but in this sentence again is the more natural interpretation, because it suggests repeated participation.

Because the verb 参加する takes に, not を, for the thing you participate in.

So you say:

• イベントに参加する = participate in an event
• 会議に参加する = participate in a meeting

This is a very common pattern and one learners simply need to memorize.

So in this sentence, the second に marks the event joined, while the first に is part of きっかけに. They have different functions.

Because Japanese often leaves out the subject when it is understood from context.

So even though English usually needs something like I, Japanese often does not say it if it is obvious. In a sentence like this, the listener will usually understand that the speaker is talking about themself.

Depending on context, it could also refer to someone else, but without context many people would naturally read it as I.

The comma marks a pause and helps separate the trigger/background part from the main action.

So the structure becomes easier to read:

• 完歩をきっかけに、 = as a result of completing the walk / taking that as a trigger
• またウォーキングイベントに参加した。 = participated in another walking event again

The comma is not absolutely required in every case, but it is very natural here because the first phrase sets up the reason or turning point for what follows.

Yes, it is understandable and natural, especially in modern Japanese.

It refers to a walking event, often something organized for fitness, tourism, charity, or community participation.

Depending on the context, Japanese might also use expressions like:

• ウォーキング大会
• 歩け歩け大会
• 散策イベント

But ウォーキングイベント is perfectly normal, especially in advertisements, flyers, and casual modern usage.

No. きっかけ can be either big or small.

It can refer to:

• a major turning point
• a simple opportunity
• a small trigger that led to something else

In this sentence, it does not have to sound dramatic. It can simply mean that completing the walk encouraged the speaker to join another walking event.

So the nuance is often that experience led to the next action, not necessarily that it changed my life.
