Hey there! It's nice to meet you, Hideo.
I commend you for successfully learning English, by the way. From this newfound skill, I hope you enjoy this place even more now, and I'm sure the learning doesn't stop from here. Being involved in a forum like this, you'll only find yourself improving on every step, especially if you have the motivation, stay active and discuss a lot!
It would also be endearing to hear from your own personal views, experiences and stories with a cultural background not commonly seen in the forum. Like Hikari said, we don't normally see Japanese members in this forum. Nevertheless, I really hope we see more of you here. Welcome to the forums! :D
PS: リザードン (romaji: Rizādon) is Charizard in English. I like that Pokémon, too.
