Send money from Japan without residency

I’m relocating from Japan to Singapore soon and will close my Japanese bank account. I don’t have a Singapore bank account yet, and Japanese banks generally don’t allow overseas transfers after you lose residency.

I already have Wise and Revolut accounts. My plan is to transfer funds from my Japanese bank to Wise (or Revolut), hold them there, and then send the money to my Singapore account once it’s open.

Is Wise the best option for this? Can I hold a large amount in JPY until I’m ready to convert?
