What to do when moving out to another area?

Hello guys.

So i will move from Nagareyama to Edogawa. All housing-wise stuffs are settled but i have a question regarding 役所 stuff as this is my first time moving inside japan.
I know what to do after moving to Edogawa, but is there any stuff i have to do in Nagareyama市役所 before moving out? Like perhaps i have to report or something?

Thank you in advance.
