It's a simple trick you may already know
To do it you will just need a vpn
You should not have already sent a pic for verification.
-open the vpn and set it to a japan server
-open a browser and go to m.facebook.com
And log in with your credentials, if you are lucky you will notice that the photo verification changed to the date of birth verification
So just just enter the date of birth you added on your profile and bam!!! you can continue to use your account like before.
