Hello, I am an English teacher in Japan. Although I make my living with people who try to learn English while living in Japan I always recommend for people with time and money, especially young college age people to study abroad.
A good friend of mine, is teaching English in the US now after spending many years in Korea teaching English. He sent me some information about the college he is working for so I've been sharing it with Japanese folks I know.
THe great thing for Japanese students is he speaks Japanese and understands Japanese culture, as does is wife (although she is Korean) because they have also lived in Japan. So he can provide support and assistance to Japanese students, even students who come with a low level of English and just need help with basic living issues. Also he is just a really really nice guy and good teacher who puts extra energy and time into making sure his students get immersed in the community, culture and language. He really cares about his students and their futures.
There will be some information made available in Japanese including flyers. If you know anyone who wants to learn English but needs information in Japanese let me know and I can forward the information. Right now the website is only in English but Japanese and Korean will be available soon.
