How to find trustworthy roommate in Tokyo?

Hi,

I'm a female student who is living in a nice 2bedroom apartment in Azabujuban-Roppongi.

I want to find a trustworthy female roommate but I really have no clue where to start?

I already rent the place and paid all the deposit and everything.

Just need a nice roommate to share the rent with.

Where everyone find trustworthy roommate in Tokyo?
