Contract ended in Japan; do I need to notify Immigration within 14 days?

Hi I’m hoping someone here can help clarify my situation.

My contract has officially ended in the first week of February. I’m currently waiting for confirmation about renewal, as the decision is pending with the Board of Education. I work as an ALT through a dispatch company.

In the meantime, I’m trying to make sure I stay fully compliant with immigration requirements.

I’ve read online that if your contract ends, you’re required to notify Immigration within 14 days. I believe the form is called 「契約機関に関する届出」 (Notification of the Contracting Organization). I’ve already crossed this mark, and I just recently discovered this, so I’m quite concerned.

However, I haven’t received any guidance from my company about whether I need to submit this notification, especially since my renewal is still pending.

My questions are:

-Am I required to submit the Notification of the Contracting Organization even if renewal is still under consideration?

-If so, should I file it immediately since it’s already been 14 days?

-Does the company typically provide any supporting documentation for this process?

-Has anyone been in a similar situation while waiting for a decision?

I just want to make sure I handle everything properly and don’t accidentally violate any immigration rules while waiting.

Any advice or shared experiences would be greatly appreciated. Thanks in advance!
