I think that traveling and studying abroad is very important.
It is true that it takes a lot of time and money to go overseas to study.
Only the rich can afford that.
However, the advantages of traveling and studying abroad outweigh the disadvantages.
First, you can appreciate cultural diversity.
Learning a language means learning the culture in which it is spoken.
Second, you need to speak the language which is spoken in the country every time you talk with someone there.
This environment will improve your communication skills.
Third, it takes no money to make friends with the natives who speak various languages.
It is said that foreigners are interested in Japanese culture, so you may come to understand your culture.
Finally, you experience many beneficial things through traveling abroad, and you can share the stories of the experience with someone.
For the above reasons,there are many benefits of traveling and studying abroad.

Sorry if I interpreted some things wrong and messed it up.
I don't really understand what you meant by "It is said that foreigners are interested in Japanese culture, so you may come to understand your culture."
What you were trying to say at the end was unclear, too, but I tried my best. Good job, though. Keep at it!
