Hello. I'm Haruka from Japan.
閉まる use when the subject is object.
閉める use when the subject is human.
If I correct your sentence, I will say;
・店は毎晩九時に閉まります。
→ the store will be closed every 9 o'clock.
Or,
・(私は)店を毎晩九時に閉めます。
→(I) close the store every 9 o'clock.
・居酒屋は今閉まります。
→the Izakaya will be closed now.
Or,
・(私は) 居酒屋を今閉めます。
→(I) close the Izakaya now.
I hope you understand and this correction will help your Japanese study! Good luck!!
