How can I get an exchange or study abroad to Japan? -

Do I need a certain grade to qualify or need to be fluent in the language? What do I need to do in order to get into a high school or college in Japan from America?

You can apply through many exchange programs for a high school year. Go to www.csiet.org for a list of those which are certified to operate in the US. Lucky for you, there are also scholarship opportunities for Japan with many of them! Generally, for Asian countries there is no language requirement, but some may require a specific GPA, usually around 2.5 or so. Good luck!
