Can anyone recommend a Japanese language school in Tokyo?

Hi,
I studied Japanese at ARC Academy in Shinjuku. They have branches in Shibuya and Yokohama as well. It is quite an expensive school (maybe THE most expensive), but a lot of people have told me they are the best, and I have often been complimented on my Japanese, and how quickly I started speaking once I started studying. I really enjoyed my classes there, and got to meet lots of other foreigners who quickly became good friends. I studied there for about a year, and stopped only because it was too far for me to keep going to Tokyo twice a week after work, as I live and work in Chiba. I have recommended this school to other people, and they were also very satisfied with it.
