I'm 14 years old self-studying Japanese for the reason... well because I love Japan.
I got started off with watching Anime, then reading Manga and most of the time the Anime or Manga I read or watched showed to some degree a part of Japanese culture. I started reading a little about Japanese culture and it just blew my mind and at about the age 12 I thought "Yep, I'm living in this country when I'm older".
Yeah the dream sounds far fetched but I want to live there anyway.
