Boa tarde, Torga kun. Welcome to the forum. Tudo bem?
Eu sou Hirashin, japonês. Am I saying it right:
Your picture is from Pokemon, right? Do you like the anime? What Japanese anime have you watched so far?
Are Japanese anime popular in your country?
Até logo. ( Is thsi too formal?)
Hirashin
Hi there, Hirashin.
When introducing yourself in Portuguese, you say: "Eu chamo-me Hirashin e sou japonês." ("My name is Hirashin and I'm Japanese.")
Yes, my avatar is from good ol' Pikachu. I've liked the anime and the games since Pokémon Red and Blue Versions were launched in 1999.
For now, I haven't watched completely any anime but I have watched a lot of episodes of Naruto, Full Metal Alchemist and a few of Basilisk, Love Hina, Chobits and Lupin III. I'll also watch Bleach, Saiyuki, Gunslinger Girl, Black Lagoon and Death Note in the future. I've also liked some classics such as Doraemon, Dragon Ball and a few others.
Anime is popular in my country since a few years ago and its popularity is increasing. By the way, and don't take me wrong on this one, but all anime (and manga) are Japanese. For example, you may find American cartoons that might share similarities with anime but they're still cartoons.
"Até logo." ("See ya." or "See ya later.") is not formal but between young people, we usually say "Fica bem.", which is an expression used to wish good luck and be away from problems yet replacing at the same time the expression used to wave good bye and see people later by adding this meaning to it.
Hope this helped and thank you for your thoughtful welcome.
If you have any more doubts, don't mind asking.
