Hi! I would like to introduce myself.

Hi everybody! I'm trying to learn English. I'm a beginner. I love Japan and want to get to know the Japanese in order to talk about Japan, Mangas and maybe learn Japanese. But I think it's difficult.
I'm from France. I like cats. I have 5 cats at my home.
I dream of traveling to Japan someday.
Thank you for your time.

I just tried to keep it standard. It may be kind of rough! But probably Japanese would like it because that's the way the robots talk! (I like cats. I have cats. I have 5 cats... I...) ;D

"the Japanese" is plural.

Again, I'm not a native! Just wanted to try how it feels!! ;)

Hi! I present myself

Hi everybody! I am trying to learn English. I'm a begginer beginner. I love Japan and I want make knowledge with Japaneses people for talk about Japan, and manga and maybe learn the Japanese language, but I think it's difficult.

I dream of one day to travelling to Japan.
Thank you for your time.

You're doing great! I love that you wrote, "I present myself." It's grammatically correct, but still sounds a little odd to me, but in a humerous way! :D

I only have one tip. Just remember that "I" is always a capital letter when used as a pronoun. Same with I'm, I'll, I'd, I've, etc.

I like French and Japanese too, but I'm already trying to learn 4 other languages right now. I think I'll learn French and Japanese later on though. Good luck! :)
