Advice on choosing a bank for Wise Transfer

Hi everyone. I am currently in Japan and I'll be here for another 6 months ( although my Visa is for 1 year). I currently have a JP account, where I recieve money. I wanted to send money back home using Wise. But figured out that I need to pay 3000 yen fees per transaction. I was wondering if it would be possible to just open a seven bank or Rakuten account, make cash deposit to those accounts and then use them to add money to Wise account for transferring it back home. I would greatly appreciate any help in this regard.
