Instant transfer to japanese bank account from non-resident?

I am looking for reasonably fast (within few hours) transfer of reasonably large (~10 mil)JPY amount. Being non resident, it's my understanding I can't apply for bank account. What are my options? I use Wise a lot and it's pretty fast, but not sure how it will work with large amounts.

Reason for said arrangement is multi optional agreement where payment needs to be confirmed withing few hours.
