About ～は～となっている
(A) は (B) となっている is a common expression used to show that '(A) is becoming (B)', or (more commonly) '(A) has become (B)'. This expression will only appear with nouns, or な-Adjectives in their 語幹 (stem form). (A) は (B) となっている is often translated as '(A) happens to be (B)', '(A) has been established as (B)', or 'it has been decided that (A) is (B)'.
Let's have a look at some examples, and then how this structure is formed.
-
鬼滅の刃は非常に人気となっている。
It happens to be that Demon Slayer is very popular.
-
日本ではドラッグは法律上、違法となっている。
In Japan, it has been established that drugs are illegal, by law.
-
このプールでは、飛び込みが禁止となっている。
At this pool, it happens to be that jumping in is not allowed.
Despite the different translations, (A) は (B) となっている always has the same meaning, which can be understood as follows:
(A) は - (A) is a constant unchanging thing.
(B) と - (B) is a result. (coming from the case marking particle と's role in highlighting results.)
なっている - (A) is existing in the state 'having arrived at the result of (B)'.
-
今の時代にはインターネットは必要となっている。
It is now that the internet is necessary in the present age.
-
この高校ではアルバイトが禁止となっている。
It is now that working part-time at this school is prohibited.
Due to this, the literal translation may be thought of as 'it is now that (A) is (B)' in almost all situations.
Caution
(A) は (B) となっている may be rephrased to (A) は (B) になっている. However, に will remove much of the feeling of a 'result', or 'finality'. Due to this, it will just sound like (A) is becoming (B), but is not necessarily that way yet.今の時代にはインターネットは必要になっている。
It is now that the internet is becoming necessary in the present age.
Caution
In writing, おる is not always considered a 'formal' equivalent of いる, especially in set phrases. となっている is often seen as となっており, instead of となっていて. This is particularly common in news articles.
このイベントは来月５日からとなっており、明日から前売り券を買うことができる。
It is now that next month's event from the 5th has pre-order tickets that are purchasable from tomorrow.

The grammar point for the formal conjunctive is a bit earlier in N3, but いる is a special case: It’s not used in this form and instead replaced with おる.
