watasitati ha bouringuzyou ni iku.

When は is used as the topic particle, it is pronounced wa, not ha.

So in:

私たちはボウリング場に行く。

the は marks 私たち as the topic of the sentence, and you read it as watashitachi wa.

If は were part of a normal word, it would usually be pronounced ha.

は marks the topic of the sentence.

Here, 私たち means we, and は tells you that the sentence is about us / we.

So the structure is roughly:

• 私たち = we
• は = as for / speaking of

A very literal feel is:

As for us, ...

Then the rest of the sentence tells what is true about that topic:

ボウリング場に行く = go to the bowling alley

So the full sentence feels like:

As for us, we go / will go to the bowling alley.

The particle に marks the destination of movement.

Since 行く means to go, you need a particle that shows where someone goes to.

So:

• ボウリング場に = to the bowling alley
• 行く = go

Together:

ボウリング場に行く = go to the bowling alley

With verbs of movement like 行く and 来る, に is very common for marking destination.

Yes, it can.

You can say:

私たちはボウリング場へ行く。

Both に and へ can mark a destination with 行く.

The difference is subtle:

• に focuses more directly on the destination
• へ gives more of a sense of toward that place or direction

In many everyday sentences like this, either one is natural.

ボウリング場 is a compound noun:

• ボウリング = bowling
• 場 = place, site, venue

So ボウリング場 literally means bowling place, which naturally translates as bowling alley or bowling center.

This is very common in Japanese: a borrowed word plus 場 to mean the place where that activity happens.

Because they come from different types of vocabulary.

• ボウリング is a loanword from English, so it is written in katakana
• 場 is a native/Sino-Japanese word usually written in kanji

Japanese often mixes writing systems in one word or phrase like this.

So ボウリング場 is completely normal:

• katakana for the borrowed activity name
• kanji for the meaning place

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

So ボウリング場 can mean:

• a bowling alley
• the bowling alley
• sometimes just bowling alley / bowling alleys depending on context

The listener figures it out from the situation.

This is one reason Japanese can feel less specific than English on the surface, but context usually makes it clear.

Japanese is usually a verb-final language.

A basic sentence pattern is often:

topic / subject + other information + verb

So in this sentence:

• 私たちは = as for us
• ボウリング場に = to the bowling alley
• 行く = go

This is very natural Japanese word order.

English puts the verb earlier: We go to the bowling alley.

Japanese puts it at the end: We, to the bowling alley, go.

It can mean several things depending on context.

行く is the plain, non-past form. In Japanese, that form can express:

• a habitual action: go / goes
• a future action: will go

So this sentence could mean things like:

• We go to the bowling alley.
• We are going to the bowling alley.
• We will go to the bowling alley.

Context tells you which one is intended.

Japanese does not mark future tense the same way English does.

Yes, it could often be left out if the context already makes it clear who we are.

Japanese frequently omits subjects and topics when they are understood.

So in context, someone might simply say:

ボウリング場に行く。

and it could still mean We’re going to the bowling alley or I’m going to the bowling alley, depending on the situation.

私たち is included here to make the topic explicit: we.

私たち is:

• 私 = I / me
• たち = pluralizing suffix for people

So 私たち literally means something like I and others, which is commonly translated as we.

It is a standard and neutral way to say we, but it is not the only way. Depending on context, gender, formality, and group identity, Japanese has other possibilities too.

Still, 私たち is one of the safest basic forms for learners to know.

It is plain style because the verb is 行く.

The polite version would be:

私たちはボウリング場に行きます。

Compare:

• 行く = plain
• 行きます = polite

The meaning is basically the same, but the level of politeness is different.

Use the polite form in many everyday formal situations, when speaking to teachers, strangers, customers, coworkers in polite settings, etc.

Yes, but the nuance changes.

• 私たちはボウリング場に行く。
  This presents we as the topic: As for us, we’re going to the bowling alley.

• 私たちがボウリング場に行く。
  This uses が, which often marks the subject more directly and can sound more specific or contrastive, like we are the ones who are going to the bowling alley.

For a simple neutral statement, は is very natural here.

Yes. Those spaces are usually just for learners.

Normal Japanese writing would be:

私たちはボウリング場に行く。

Japanese normally does not put spaces between words the way English does.

Textbooks and beginner materials often add spaces to make the sentence easier to read and to show where particles and words are.
