Language School Japan

Hi,
I am an American guy currently looking for a language school to attend in Japan. I'm definitely looking to be in an environment where I won't be able to use English outside of class. I've studied Japanese for a while and worked for a Japanese company for a bit.

I recently had a trip to Japan where I visited Samu Language school. I went to the school briefly and had a quick interview where I saw I was assessed at conversation level 3 (whatever that means). School seemed pretty good, and I was told by the
staff that the school has lots of folks from Korea and China. (Might be good seeing as I'm hoping to only use my Japanese)

I haven't been able to find any reviews on the school and was wondering if anyone has attended the school and could give me some insight. I've seen seen a few of the other big names floating around (Kai, Naganuma etc.) Please let me know your thoughts.

I do not know anyone who attended that particular school, so I cannot give any first-hand recommendation, but if you want to look around, you could search on this list of accredited Japanese language schools to, for example, compare student mix.

Having the majority of students either Chinese or Korean has the advantage that you might be exposed more to the Japanese language only, and also has the con that they (particularly the Chinese) are quick with learning writing/reading and vocabulary building due to the common writing, that you will definitely feel the difference.

This is in the middle of Tokyo, so for daily living it is likely that you will be able to get by in English - meaning you won't really be forced to use only Japanese... something like Yamasa Institute might be an option too, with dormitory.
(Again this is not a personal recommendation; my non-Japanese spouse went to Naganuma and was/is happy with it, but that's many years ago.)

Thanks so much for the feedback man!
