關於Sendai的意思和用法的提問

A: "Uni" is a casual abbreviation. It's common in casual speech but you usually wouldn't use it in more professional situations.

I think saying "uni" is also more common in European English, though I have heard some Americans say it too..

A: Why don't you visit the beautiful city of Sendai? Sendai is not very familiar to people who live in Kansai. However, you can go there in one and a half hours by plane from Kobe airport.

A: × Sendai City, Miyagi Prefecture, is located in the northern part of Japan, but it does not snow much.
✓ Sendai City, (in) Miyagi Prefecture, is located in northern Japan. Even though it is in the north, it does not snow very much, and as such rarely accumulates.

Here is one way of saying it. I think that it seems pretty formal. Also, the "in" isn't necessary if you want to sound like a Wikipedia page.
Btw your sentence sounds natural but I've gotta put "A little unnatural" so I can make an edit.
Other example:
"Sendai City is in Miyagi Prefecture, which is located in northern Japan. Although it is so high up north, it doesn't snow very much, and rarely accumulates." -- this one sounds a little less formal/informational.

A: × Sendai Umino-Mori Aquarium situated 20 minutes by local train from Sendai station is worth visiting.
✓ Sendai Umino-Mori Aquarium, situated 20 minutes by local train from Sendai station, is worth visiting.

× This aquarium features the Sanriku ocean that is unfamiliar with.
✓ This aquarium features the Sanriku Ocean that some are unfamiliar with. (1)

× However, you would know how large kinds of unique fishes are existing and it has a great abundance of resources that all crucial for our life.
✓ However, you can learn about the large kinds of unique fish in it, and its great abundance of resources that are crucial for our life. (2)

(1) We have to say *who* is unfamiliar with the Sanriku Ocean
(2) The plural of "fish" is "fish"! It can be difficult to translate ある/です to English, since they can be "to have / to be / to exist".

A: "Sendai is a great place to live in. It has the most comfortable climate among the main cities in Japan. You can enjoy the four seasons without suffering from extreme temperatures in the summer and winter.

A: Understandable, but I would suggest three changes:

I think of "northwest" as a direction and "north west" as a place (so I suggest "north west")

Isn't Sendai in the north east of Japan? (So I actually suggest "north east")

I think "refers to" is better than "means". "仙台 means a city in Japan" might make people think something like 仙=city and 台=Japan.

Sendai is located in the north east of Japan.
(The word “Sendai” refers to a city in Japan.)

A: I travelled to Sendai with my son from the 8th to 9th of this month. The primary goal was to eat Gyutan, which is a famous Japanese dish made from cow's tongue. We found a good restaraunt offering Gyutan by searching on the internet and went there. There was a line in front of the restaurant and we waited about 30 minutes. The dishes were extremely tasty and was beyond our expectation. It was worth waiting half an hour.

The famous festival called "Tanabata Matsuri", which means star festival, had been held during our stay. Unfortunately, it rained heavily and we could not enjoy it very much. Instead, we went to "Onsen", which is a hot spring, and we had a relaxing time. Although the weather was not good, we had a wonderful time in Sendai. Of course, we remembered to buy some souvenirs for the rest of our family.
