Can I become a seiyu?

Hi, my name is Sunny. I'm Korean and 13 years old. Since I was young I wanted to become a seiyu and I've started studying Japanese on my own. Do I have to go to a voice acting school in Japan and if I do about what age do I go? Can a Korean girl become a Seiyu? Please tell me some step I can do to become a Seiyu!!

まずは、とにかく日本語を流暢に話せる必要があるでしょう。
∀ガンダムの主人公、ロラン・セアックの声は韓国籍の朴璐美さんでした。
彼女は在日３世で日本語ペラペラですが、帰化していないので、声優は日本国籍である必要はないってことでしょう。

At first, in any case, you need to speak Japanese so fluent.
The 声優(seiyu; voice actress) of Loran Cehack who is the hero of ∀GUNDOM is Paku Romi who has South Korean nationality.
She is the 3rd generation Korean in Japan and speak fluentl Japanese but not naturalized Japanese, so 声優 is NOT required Japanese nationality, I think.

Sorry double post.(x_x;

BTW, Loran Cehack is a boy who have brown skin, silver hair and emerald eyes.

P.S. がんばってね！(^-^)/

Do you think you are capable of becoming an actor in your home country?
As in Japan things will be twice as hard.
Not just anybody can do the job, you need to have ability and/or contact and/or luck.

Good luck to you but bare in mind it will be hard

good luck. maybe you can send them your portfolio, and who knows they might like it
