それぞれの州にそれぞれの魅力があるって英語でなんて言うの？

魅力を訳すのにAttractionを使いたがりましたが、こちらは「Charm」を選びました。

「Attraction」だとどうしても、その州が何かを外に向けてアピールしようとしているように聞こえてしまいます。でも、そう言うのではなく、「魅力的な特徴がある」と言うニュアンスだと思います。

例えば、DisneyLandは魅力があるかもしれませんが、商用じゃないですか。

各州の魅力は商用ではなく、その州の人たちとその文化が魅力を指しているのかと思います。

よって、「Each state has its own charms」を選びました。

Each state has its own distinctive quality and beauty.
Each state is beautiful in its own distinctive way.
Each state has a distinctive attribute or aspect to itself.

Each one of the United States is different. They speak the same language but the laws can be different. Some states never see snow, while others see too much snow. The country is so vast and each state has something to offer to tourists.

"Unique" is another way of saying different or one of a kind. Sometimes we can use this word to refer to people as well.

"Loveliness" is another way of saying very attractive or beautiful.

All three of these sentences can be used to have the same effect in meaning and can be used interchangeably. The main difference between the first two is the usage of the words, "charm," and, "appeal," as these describe the things that might interest someone when visiting the state.
The last one is being a bit more descriptive while also stating that each one is, "unique." It also mentions that each one is, "different from the next," to really emphasize that each state is quite different from one another.

Each American state has its own charm.
Each state in American has its own appeal.
I believe that each state in America has its own charm.

When you want to state that each state in America has its own charm, you can use one of these three sentences. You can swap and change charm and appeal as you wish, and it won't change the structure of the sentence at all, nor will it make it incorrect. Personally, I would go with the first one, 'Each American state has its own charm.' Pick one and good luck with it.

I hope this helps.
Have a great day.
Will
