Intensive course for Japanese (Tokyo)

Hi
In Germany we have the official courses from the Goethe Institute preparing people for work in the University or for work, are highly intensive over a course of Protected content . I have found a few schools for business japanese which I really don't want to go to as in my experience the business english courses in Britain are a complete desaster / rip off , where people go in to learn a few buzz words to compensate for virtual no actual language learning whatsoever. Thus if anyone has a recommendation for a fast moving intensive course I'd be grateful.
