No. Normal Japanese writing does not usually use spaces between words.
This sentence would normally be written as:
この技術は新しいです。
Spaces are often added in beginner materials to make it easier to see the parts of the sentence.
技術 is read ぎじゅつ.
It usually means:
The exact English meaning depends on context. In this sentence, this technology is new is a very natural interpretation, but in some situations it could also mean this technique is new.
This is one of the most common beginner questions.
When は is used as the topic particle, it is pronounced wa, not ha.
So:
But when は is part of a word, it is usually pronounced ha.
Example:
So in your sentence, は is the topic marker, so it is read wa.
は marks the topic of the sentence.
So この技術は means something like:
Then the rest of the sentence says something about that topic:
So the full structure is:
Japanese often works like Topic + comment.
Yes. 新しい is a complete i-adjective and means new.
Japanese has a type of adjective called an i-adjective because its dictionary form usually ends in い.
Examples:
In this sentence:
Then です is added for politeness:
So 新しい is doing the main descriptive work.
Not exactly.
In beginner translations, です is often translated as is, but that can be misleading.
In a sentence with an i-adjective, the adjective already carries the main meaning:
この技術は新しい。 = This technology is new.
casual/plain style
この技術は新しいです。 = This technology is new.
polite style
So here, です mainly adds politeness, rather than acting exactly like the English verb to be.
That is why:
You do not use だ after an i-adjective.
Yes.
You can say:
This is grammatically correct, but it is plain/casual style.
With です:
This is polite and more appropriate in many everyday situations, especially for learners, formal speech, or speaking to people you do not know well.
Japanese sentence order is often different from English.
English:
Japanese:
A useful way to think about it is:
So Japanese does not always try to match English subject + is + adjective directly. Instead, it often presents the topic and then comments on it.
Yes, it is a natural and correct sentence.
It is a standard polite sentence meaning that the technology or technique in question is new.
Depending on context, native speakers might also say things like:
But この技術は新しいです。 is perfectly normal and good Japanese.
No. Japanese often omits information that is clear from context.
In this sentence, この技術 is stated explicitly, but in conversation it could be omitted if everyone already knows what you are talking about.
For example, after pointing at something, a person might just say:
This is one reason Japanese can feel very different from English: context matters a lot.
