What I can'tI will never forget about a meet-up I went to during the New Year's holiday is that w. We talked about wars.

Do you know which prefecture got the worst damage during the wWorld wWar I and II?

the World Wars or World Wars I and II

This question was asked by an European man to us, attendees.

We like to use active verbs/sentences/clauses, passive isn't so common and is frowned upon in writing.
"A European man asked us this question"
Also its "A European" because, while it European starts with an E, it technically starts with a consonant sound and therefore you shouldn't use "an"

Many people, including me, answered Hiroshima and Nagasaki, but actually it was Tokyo.

In Hiroshima, the dead bodies wnumbered around 166 thousand, and in Nagasaki were around 74 thousand people died within 4 months after people werebeing exposed to radiation infrom the atomic bombing.

Talking about dead bodies isn't something we do often. We talk about 'the dead' or people dying. When you talk about "dead bodies" or "corpses" it makes it sound personal. If someone said to me, "there were so many dead bodies", I would think that they themselves had seen all the dead bodies.

However, Tokyo'd continued to be destroyed in 106 was attacked 106 more times by air raids, and many buildings and stations like Tokyo sStation were burned down.

At onlyBy the time of the night air raid of March 10 in 1945, the dead bodies were more than 100 thousand people died.

The total number of victims and the suffers came to over 1000 thousand in total.

At the end of the war in 1945, Tokyo was just a burnedt field, yet, in 1964, Tokyo Olympic was heldheld the Olympics.

"burned" is the past participle of "burn" but "burnt" is the adjective.
To further illustrate; "The toast got burned" and "He ate burnt toast"

To make it in time for the opening on October 10, the Shinkansen (Bullet Train) started in poperacticeng on October 1.

or "was put into operation". I also do not know if there was only one Shinkansen or multiple. If multiple trains were put into operation, I'd rather say "the Shinkansen service"

Before that, an/the expressway was opened in 1963 as well.

Thise recovery and growth hasn't made people to bring upresulted in people not talking about this event so often, but the tragedy was more cruel than Horoshima and Nagasaki.

I think I learned this eventabout this at schools, but forgot most of them(a lot) about it.

This European guy explained showing theand showed photos of Tokyo of before war and after warthe war(s).

or "explained by showing"

I was very ashamed that I had learned about my country's history from a person from another country (-""-;). I asked him why he'd learned so much about another country's history so much, then h. He answered that he's been cares about other countries' histories because his country'd has had many wars from the reasonsbecause of religions, races and the territory from way before/land disputes.

I wasam now painfully aware of the importance of learning historiesy for cultural exchanges.

I deeply reflect on whathow little I thought little of historiesy (T_T)

What I can't forget what I learned at a meet-up I went to during the New Year's holiday is thatwhere we talked about wars.

Do you know which prefecture gotsuffered the worst damage during both of the world war I and IIs?

Or you could say "during both World War I and World War II"

Many people, myself including meed, answered Hiroshima and Nagasaki, but actually it was Tokyo.

In Hiroshima, the dead bodies were around 166 thousand people died, in Nagasaki were around 74 thousand were dead within 4four months after people wereof being exposed to radiation infrom the atomic bombing.

Numbers up to ten are normally written out. Above that you can use the numeral. But you must use either the words or the numerals, you can't mix - 74 thousand is wrong, it should be 74,000.

This European guyman explained the story, showing the photos of Tokyo ofrom before war and after the war.

Guy isn't wrong but is a bit casual, more used when speaking than when writing.

I was very ashamed that I had to learned about my country's history from a person from another country (-""-;)I asked him why he'd learned so much about another country's history so much, then h. He answered that he's been cared about the history of other countries' histories because his country'd had been part of many wars forom the reasons of religions, races and the territory from way before.

I was shocked atby his story.
