Is there any collage on international trading in Japan that has English courses?

Question:

I'd like to become a travel guide, and since my boyfriend studies in Japan, I wanna know my choices.

Answer:

There are just less than 5 colleges who have classes mainly in English.

One is Temple University. But I'm not sure if they have international trading.

Anyway, your choice is severely limited.

Addition:
>2nd update: okay and if I wanna attend a Japanese course do I need to speak the language as if I were a native?

Sure. You have to acquire college level Japanese before joining a Japanese college.
