kare ha puro no syasinka desu.

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

So in this sentence:

彼はプロの写真家です。
it is read:

かれ は ぷろ の しゃしんか です
with は sounding like wa.

This is a special pronunciation rule for the particle は. When は is part of a regular word, it is usually pronounced ha.

は marks the topic of the sentence.

Here, 彼は means something like as for him or speaking of him. The sentence then says something about that topic:

• 彼は = as for him
• プロの写真家です = is a professional photographer

Japanese often works as topic + comment, rather than following English sentence structure exactly.

Here, の connects two nouns and shows that the first noun describes the second one.

• プロ = professional / pro
• 写真家 = photographer
• プロの写真家 = professional photographer

You can think of の here as turning プロ into a modifier, so it describes what kind of photographer the person is.

This use of の is very common:

• 日本の車 = Japanese car / car from Japan
• 学生の本 = student's book
• プロの選手 = professional athlete

プロ is a loanword, originally from a foreign language source related to pro / professional, so it is written in katakana.

Katakana is commonly used for:

• foreign loanwords
• onomatopoeia
• emphasis
• some technical or modern terms

So プロ is not native Japanese vocabulary in the same way that 写真家 is.

写真家 is read しゃしんか.

It breaks down like this:

• 写真 = しゃしん = photograph / photography
• 家 = か = a suffix meaning someone who specializes in something

So 写真家 means photographer, especially in the sense of a person whose profession or specialty is photography.

です makes the sentence polite and functions like a polite copula.

In a sentence like this, it corresponds roughly to English is / am / are, depending on context.

So:

• 彼はプロの写真家です。 = He is a professional photographer.

But it is important not to think of です as a perfect one-to-one match for English is. It is better to think of it as the polite way to end an equational sentence.

A less polite version would be:

• 彼はプロの写真家だ。

Japanese does not usually have articles like a, an, or the.

So プロの写真家 can mean:

• a professional photographer
• the professional photographer

The exact meaning depends on context.

In this sentence, English usually translates it naturally as a professional photographer, but Japanese itself does not explicitly include that article.

Yes, very often.

Japanese frequently leaves out subjects and topics when they are clear from context. So if everyone already knows who you are talking about, you could simply say:

プロの写真家です。

That could still mean:

• He is a professional photographer
• She is a professional photographer
• They are a professional photographer / professional photographers
• even I am a professional photographer

depending on context.

So while 彼 is grammatically fine, Japanese often sounds more natural when unnecessary pronouns are omitted.

Sometimes, but the nuance changes.

• 彼はプロの写真家です。 = As for him, he is a professional photographer.
• 彼がプロの写真家です。 = He is the professional photographer / He is the one who is a professional photographer.

So:

• は marks the topic
• が tends to mark the specific subject, often with more focus or contrast

If you are simply introducing information about him, は is the natural choice.

The basic structure is:

彼 は / プロ の 写真家 / です
topic / noun phrase / polite copula

A helpful way to see it is:

• 彼は = as for him
• プロの写真家 = professional photographer
• です = polite sentence ending meaning roughly is

So Japanese is not copying English word order. Instead of thinking strictly subject + verb + object, it is often better to think in terms of:

topic + description

Not as much as English speakers often expect.

In English, you must usually say he. In Japanese, people often omit pronouns entirely when the person is understood from context. Because of that, 彼 can sound more explicit than necessary.

So while 彼 definitely means he or boyfriend depending on context, native speakers often avoid using it unless they need to clarify who they mean.

That means this sentence is grammatically correct, but in real conversation, Japanese might more naturally drop 彼 if the listener already knows who is being discussed.
