As an American guy living abroad in Japan, sending money between the USA and Japan is something I'm used to dealing with. In fact I documented the various international money transfer methods I've used over the years here: How I Send Money Between my Japan and USA Bank Accounts - Life Abroad
Always on the hunt for what's new, I came across Xoom.com, a site operated by Paypal that appears very similar to my current favorite money transfer service Transferwise. What the hell...let's give it a shot. At the very least it would be beneficial to have an alternative on hand in case Transferwise ever fails me.
