International hardware releases? Japan?

(*Paging Sam Byford...*) I've upgraded my desktop ThinkCentre to Windows 8, and my only bump was getting the video driver updated. Since then I've found Windows 8 to be peanut butter and chocolate, two great tastes that taste great together. Anyway, my current mobile device (is there a term that covers laptops and tablets but not phones?) is a first gen iPad, and I'd like to upgrade to a Windows 8 tablet/convertible. I live in Japan, and I've looked around at various vendor and reseller websites, but it doesn't look like any of the new hardware is shipping here yet. Lenovo, Acer, Sony, HP, etc. do not have listings even. Lenovo is such a tease. The Yoga is used in the front page advertising but there's no information about it anywhere on the site. Dell does have the flippy convertible on the store, but that design is probably my least favorite of the convertables. Another glaring hole is the Surface. Do we have any reports of the surface being released in Japan? How about the Pro? I hope it launches here at the same time as it does elsewhere. This could very well be my next...
