Korea or Japan

I'm a young highschool art student and i really like korea and Japan, but I'm not sure which one to choose. I like animations, digital art, webtoon, concept art, character designs etc and currently my major in highschool in graphic design. I would like to use two years of my highschool before I graduate to study korean or Japanese but I'm not sure which one to choose. Which country would I as a foreigner succeed more? Im which country do i stand a chance? I would say I'm more introverted but i would like to change that and really have people and friedns around me but I'm worried about how much fun would i have and if people will accept me and also because of the jobs and stuff. Over all i just need advice to see where i should go and which one should i chose.
