Jobs in Japan for Americans?

You have to wait until you get a college degree if you want to go to Japan. I don't think classes in high school will make much difference unless you take Japanese classes. Japanese class will help you somehow.

Wow, you are an enthusiastic chap. Good on you. There are several options in Japan, a guy like you may get burnt out easily having to teach English. It may be worth your while to go in University, or spend at least a year in a study abroad program inside Japan. As long as you keep your enthusiasm, improve your language ability, and show an ability to work hard, I'll bet many academic programs and scholarships would love to have a student like you. While in uni, find something that you like. You may decide that you love the language so much, you want to stay in academia as a teacher of Japanese or linguistics or culture or history of Japan, and then you need to spend another decade or so in Japan working on your thesis and Masters or Doctorate. Or you may decide to go into media/entertainment. That is another path that is not blocked for foreigners, and will allow you to be immersed. Other things you can do are IT, business, journalism, translation,.... you will find something. Don't think just because you're a foreigner you have to be an English teacher of something, because that is untrue. Also remember that networking and having コネ is more important in Japan than just about anywhere in the world, so keep that in mind whenever you're dealing with Japanese. You never know who may be able to hook you up with something.

well what rich people do is they go to a japanese language school (within japan of course).　these schools prepare foreighners for college in japan (mostly chinese & koreans) I dont know about you if your gonna be able to do that or if you parents are willing to pay for it, its not that expensive I guess, they are around 1500$ per semester (every 3 months) & 6000$ a year. but also your gonna need your other fees like dormitory & your 生活必要品 & stuff. but thats what I did for around 2 years & a half, Im fortunate enough to have a rich family I guess lol. but the good thing is that your can atleast take up a part-time job if you are doing that on a studet visa( of course only if you japanese is good enough) you can even work in convinient stores like I did which is a very japanesy environment (because most gaijin are boring english teachers anyways). anyways you dont need any 4 year degree to live in japan, these people here need to shut the hell up. I came to japan when I was 17, no college degree & graduated from highschool with only a GED LOL, because I was acually homeschooled. but I guess that my case is much more rarer than normal people, my parents spoil me I guess, they pay for my studies here. I must be lucky かな Im going to japanese university now. so yah my degree will be from a japanese system of education, & I dont even have a degree from my own country LOL. Anyways dont give up your dreams, japan is a very nice place. I came to japan because I hate gaijin from my own country LOL. gaijin are stupid, just like there answers here . I must be turning japanese ww笑
