Digital nomad visa will expire before entry

I had a Japanese digital nomad visa, unfortunately, due to the Iran conflict and closed airspaces I am not going to be able to enter before it expires.

Can I still enter as a bona fide tourist without issues for 3 months as my accommodation was already prepaid and non refundable?

How should I go about it with the immigration officer? Will my expired visa automatically show up when they scan or how does it work?

Edit – sorry UK citizen

TIA
