Best libraries in Tokyo

Moving to Tokyo in 3wks with elementary and middle school age children. We will be in temporary housing, while we secure a permanent housing solution. I would love to secure housing near a nice library!

We are big on doing our studying and reading outside of the house and have used several libraries where we currently live to do this. Now that we are moving to Tokyo I'm trying to find which are the best libraries in Tokyo that might offer study rooms and/or a nice selection of books in foreign languages?

I have learned that the main Minato library by Tokyo tower, even though old, has a great selection of books in English. However, it seems that this library doesn't offer study rooms. Have you had any luck with a library that offers both of these things? Or at least excels in one of these? Thanks in advance for the recommendations!
