Keeping mizuho account while living abroad – KYC docs

I set up my mizuho account when I lived in Japan permanently (2006). Until recently it hasnt been a problem with the exception of not being able to activate the online ID verification for wire transfers (dont need this service as we now use Wise). However at the end of last year I received KYC documents from Mizuho, and since I no longer live in Japan I could not provide them with a resident card. I filled in the forms as best as possible, but worry that they will shut the account which I use to pay creditcards, cellphone bill etc.

We did recently buy a house in Japan and I don't know if that matters or not.

Any advice?
