To enhance my conversations at language exchange meet-ups, I want to prepare some questions.

To those who have been living in Japan for several years.:

1. Is there anythingHas your image of Japan has changed compared after coming to Japan with beforsince coming to Japan?

You don't need to specify that you're comparing with their image of Japan before they came since that's implied by "since coming...".

2. What dido you find Japanese people are strange or weirdstrange or weird about Japanese people?

I hate a packed (crowded) trains.

Packed trains cannot have been improved at all while technology has advanced rapidlyEven though technology has rapidly advanced, trains are still packed.

I always thinkwonder how many years we shouldwill have to wait for the issue of packed trains to be bettersolved.

Why does the Japanese government encourages to buildhe construction of tall buildings in the center of Tokyo and doesn't encourage to build them in the outskirts of Tokyo even thoughnot in the outskirts despite there arebeing many cities undeveloped in the outskirts.underdeveloped cities in those areas?

If those buildings arewere more evenly dispersed , I think the outskirts, I think packissue of crowded trains might be improved.

I feel always feel miserable towhen I see a train on the opposite lanetracks is almost empty while the train I getone I am getting on is fully packed.

4. As you may know, there are some people on the bicyclescyclists who shout "gGo away!" or almost rushn into us without saying anythwarning when we are walking on the streets.

I really want to kinock them downover.

5. Some people say their characterspersonality changes when speaking in English andversus when speaking in Japanese.

Does your characterpersonality change as well when you speak both languagesin this case?

Tto those who have been living in Japan for several years.

Make this one sentence :)

1. Is there anythingHas your image of Japan has changed compared after coming to Japan with before coming to Japan?

This is way too long and long-winded so I made it short. There are a lot of ways you could write this but I figured it would be easy to rewrite it entirely. You could also say "How is your image of Japan different from how it was prior to coming?" or something. Whatever works for you, just make sure not to pack to much into it :)

2. What did you find about Japanese people arethat was strange or weird?

Don't forget to add "about" in this case, as it sounds like you are referring to Japanese people as a whole, single subject and not their specific qualities. Simple mistake with an easy fix! :)

I hate a packed train.

Me too

Packed trains cannot have beenThe issue of packed trains has not improved at all while technology has advanced rapidly.

If you are trying to say the issue of trains being packed hasn't been rectified or fixed in contrast to technological advances then this is a better way to say it, as "cannot have been improved" doesn't make sense. I would also say "The issue of packed trains has not changed at all while technology has advanced". Again, a lot of ways to word this but here are some suggestions :)

WhyI don't know Japanese government encourages to buildhe construction of tall buildings in the center of Tokyo and doesn't encourage to build themheir construction in the outskirts of Tokyo, even though there are many cities undeveloped cities in the outskirts.

I don't know if you are asking a question here or making a remark like "why the Japanese government does etc. ..., I will never know" . I'm going to assume you were not. Also, I changed how you said "encourages to build..." as I feel "the construction of..." sounds more natural. Good work so far though!

If those buildings are dispersed in the outskirts, I think the issue of packed trains might be improved.

Sounds more clear and natural to me this way.

I feel always feel miserable to seeing a train on the opposite lane is almost empty while the train I get on is fully packed.

These aren't totally necessary changes but I think the way I wrote is again more clear and natural, as these sentences feel unnecessarily cluttered and long-winded to me. The only thing that would be necessary is the the order of the words "feel" and "always" at the start, other than that it works :)

4. As you may know, there are some people on the bicycles that shout "go away!" or almost rush into us without saying anything when we walk on the streets.

I really want to kick them down.

Yo chill

5. Some people say their characters changes when speaking in English and when speaking in Japanese.

Changed the "s" here to sound better.

Does your character change as well when you speak both languages?

Do you mean character as in personality or demeanor? Perhaps those are alternative words you could use in place of "character". Up to you, but no issues here. It still makes sense.
