The differences between British English and American English

When I was a student, I liked studying English.
That’s because I was a big fan of British Music, so I used to translate English lyrics to Japanese using an English dictionary. I just wanted to know the meanings.

So I thought I was used to British English (BE).
In Japan, however, we learned English from the American side as a second language at school.
And I have watched loads of Hollywood films so far.
Actually I actually got used to American English (AE).

Anyway, I found some differences between BE and AE.
Firstly, pronunciation. for me, I would say, and other Japanese people as well, BE is easier to imitate.
Especially the "R" sound “R” in AE is really difficult for us.
If I pronounce “car” like the AE way, (actually I can’t though) I feel so embarrassed!
Because we have no “R”sound like AE.
“T”or “O” of in AE are difficult as well. (for example, in party, hot water bottle, etcbetter...)

Secondly, words and sepelling spelling. Football vs. soccer, theatre vs. theater, etc.

Finally, intonation. It’s so hard for me to explain. I would say BE is clear and bit strong, on the other hand AE is very soft.

Anyway, I would like to find more differences between them, including culture or customs while learning English.

Well done! I really enjoyed reading your entry.

The yellow highlights are my corrections.

The green highlights are things I changed to sound more natural. For example, I think it's better to use etc. = など instead of ... but I don't think ... is incorrect.
