Lots of Asian countries get their beef from Australia via Live Export, so it's probably Aussie cattle, and grass-fed is the fashionable thing right now - we're not into marbling, unlike European markets. Not sure about organic though, Australia has a lot of pests and insects, so organic can often be considered cruel, as it means no immunisations or insect repellant sprays as well as organic feeding.
Personally I'd eat that, even though advertising Waygu (and Angus) beef as better beef is just a pretentious way of selling that particular beef for more, because there's less to sell on the smaller breeds of cattle. It doesn't actually taste any better!
