My main language is Spanish, second language Catalan and third one English. I can speak Catalan and English as well as a native person (though I was born in Catalonia, I didn't learn Catalan until I was 7 years old or so).
I also know a little bit of French, I almost can understand 100% of writen Italian, know some words in Chinese and Korean (only spoken, never tried writing) and in Japanese I know how to present myself and the numbers, nothing more for the moment. I know a little bit of hiragana, katakana and kanji. So when trying to read Gothic & Lolita Bible I can distinguish some of the letters and even understand one or two words (shiroi, arigatou and few more). Luckily, I have no problems when I see Hamasaki Ayumi or Kôda Kumi written xD
