There are a lot of small eikaiwas around, so good luck to you. Things might be quite hard for a while, depending on whether you've already built up a good bunch of private students on the sly while working at a bigger school, or something like that.
I see you've moved from Ashiya to Sannomiya. What great places to live! I visited Kobe a few months after moving to Japan and instantly wanted to move there.
Again, good luck to you.
