Change of SOR application

I’ve been in Japan 2 years and I submitted my change of SOR application 1 week prior to my visa end date. I got my residence card stamped and I extended MyNumber.

I’m currently approaching the end of my 2 month grace period and now I’m starting to worry. I haven’t received any calls from immigration or my postcard.

For some context, I’m changing from working visa -> child of a Japanese national at the Tokyo immigration office.

Anybody with a similar experience, let me know what you did and how things turned out for you.

Thanks
