Japanese Number/Cell Phone Help

I recently moved, and ported my US number to google voice and got Y mobile with a Japanese number because the service is much better than what my US provide had out here. So I have my US sim still and an Esim for Y mobile I guess.

However, I cannot for the life of me, figure out how to enter my Japanese number into anything. It has the 070-XXXX-XXXX format. Unfortunately, Google voice decided to lock me out, and so any 2 step verifications that used my cell number are not working right now. So I am trying to add my Japanese number so I can get texts that way, but I keep getting error messages when I try to add it into any banking system. If any one can help that would be awesome.
