I'd love to be part of a questing anime world, like Fairy Tail, or One Piece, though I didn't finish either anime, I liked their worlds, despite disliking some of the plots in the series, if it was real life I could choose my own quests.
That, or just live in an anime where I was a normal human, but in Japan.. yes, life would be more full for me in Japan, drinking tea in a tea house and growing up with martial arts (preferably taught in the home) and at school.
