What are Some Private All Girl Schools in Tokyo, Japan?

Question:

I'm working on a story in which the main character is briefly in an all girls private school in Tokyo, Japan. I would prefer more expensive schools, but not extremely expensive ones. Can anyone tell me the names of some elementary, middle school, and high school all girl private schools there? Thanks!

Answer:

Seisen?　Seisen is co-ed at elementary level. Seisen International Elementary is all-girls. But I'm not sure if the asker is asking for international schools.

I think Seishin is one like that.

This is an all-girls school from elementary to college.
