Company Dorms

[ptbrock]

I'll be starting work at an investment bank in Tokyo this October.
For the first year, I'll be living in the company dorms with other new employees.
I was wondering if anyone has any experience with company dorms in Japan or knows of someone who has lived in them.
Any information about typical size (besides obviously being small), quality, facilities, rent etc. would be more than appreciated.

Thanks in advance
