Need some input on the following Japanese Language Schools...

[AlwaysPEPSI]

I am looking to go to a Japanese Language School for a term possibly after my final year of college, which will be over this June. I am not sure whether I will want to continue staying in Osaka or go to Tokyo for the school. I am more comfortable with Osaka at this point, but career-wise it seems that Tokyo may be better because there are a great deal of job fairs there. The purpose of going to these schools will just be to get me over the hump so I can pass JLPT-1 so I will only be looking to go to these schools for one term starting in July.

*Note: I will be wanting to enter these schools in July so all of the following schools have a term starting then. If you want to recommend me a school please make sure I can start in July! Thanks-

So, if anyone has input on these schools, I would love to hear it!

Osaka:
Clark Foreign Language School
Human Academy Japanese Language School
Osaka International School of Culture and Language

Tokyo:
System Toyo Gaigo
Edo Cultural Center
