GenkiJACS Tokyo, thoughts?

I've done a lot of research on different language schools. I want to attend for 2~3 months before I start my job. I'll be doing it on a tourist visa.

I'm a complete beginner and want to focus mostly on speaking and culture which is why I've decided on Genki JACS, although I know the teachers rotate often and the schedule is not set. It's been hard to find any recent experiences on the Tokyo campus as most people get student visas at other campuses.

Does anyone have thoughts on whether it's worth the higher price tag? I'd be doing the beginner 10 week course.

Or if you have any suggestions in the shinjuku/shibuya region that focus more on speaking than test skills, I'd appreciate it!

Thanks in advance.
