Paying company bills before opening corporate bank account

I'm on a four-month business manager visa, and currently in the limbo between having submitted the 法人登記申請 and having successfully received the one-year BMV. I'm paying for office space and other company expenses using my personal Wise card, but would like to shift these over to the company as soon as the registration is complete, as well as sign up and pay for things like a company phone, liability insurance, etc.

My questions is: Is there any feasable/efficient/convenient way to do this without a corporate bank account?

I set up my company solo with the startup capital in a Japan Post bank account. I now have less then three months remaining on my residence card, so it's not possible to open another personal bank account yet. Checking the regulations of a few banks, it also seems like it's not possible to apply for a corporate bank account with less than three months remaining, and the general concensus seems to be that getting accepted for an account can be tough/take some time even if all the boxes are ticked.

So how to bridge this gap? Am I stuck with doing Japan Post bank transfers and using my personal Wise card until I get a corporate bank account, or is there another option? Any advice or information would be very appreciated.
