There are times when cafes or shops close down temporarily in order to undergo refurbishment. They may redecorate or order in a large set of new stock.
In order to explain that a shop was closed before and then reopened, you can say:
The store has reopened.
The shop has reopened.
The cafe reopened on Saturday.
I noticed they reopened last week.
I hope that helps!
改修のために、お店やカフェが一時的に閉店することがありますね。店内を改装する場合もありますし、在庫を大量に仕入れる場合もあります。
閉店していたお店が再開することを表す場合、次のように言えます：
The store has reopened.
（その店は再開した）
The shop has reopened.
（その店は再開した）
The cafe reopened on Saturday.
（そのカフェは土曜日に再開した）
I noticed they reopened last week.
（先週再開したのに気が付いた）
参考になればと思います。
The cafe, closed after the earthquake, has now reopened
To indicate that something has happened again, you can often use the prefix 're-'.
"I have to repaint my living room a brighter colour. This colour is depressing!"
何かが再び起こることを表す場合、接頭辞の「re-」がよく使われます。
I have to repaint my living room a brighter colour. This colour is depressing!
（リビングをもっと明るい色に塗り直さないといけない。この色は重苦しい。）
When something has reopened, it usually means that it was opened before, then closed and now is opening once again. This can happen for various of reasons. Shops usually close down for a period of time due to renovations. This also happens when the shop closes for a while because the owner is unable to pay the rent.
To be back in business means that the shop in open and ready to offer goods or services to the public.
"has reopened"は、以前に店を開いて、いったん閉めて、また今営業していることを表します。これはいろいろな理由で起こります。リノベーションのために一時店を休業する場合もありますし、オーナーが家賃を払えなくてしばらくの間店を閉めることもあります。
"be back in business"は、店が営業していて客に商品やサービスを提供する準備が出来ていることを表します。
To say that something is "up and running" means that it is functioning again, especially if it was not working for some time. If someone "runs" something, they are operating it and it is in business. These expressions explain that someone is actively in charge of the cafe and that they can serve customers again.
「up and running」は、特にしばらく動いていなかったものが再び動き出したことを表します。「run」には「営業する」という意味があります。これらの表現で、カフェの営業が再開されたことを表せます。
