The chatter on slickdeals.net forums (yes, Someone on the Internet Told Me...) is that Ikea has switched to a lower-quality Chinese supplier, and theirs are not white-labeled Eneloop anymore.
The brown versions with lower capacity / higher cycle life did switch from Japan to China, but they've discontinued those(or at least no longer stock them @ my local store) for some years now.
The white Eneloop Pro comparable ones were and still are made in Japan.
No way to tell country of origin from their web, and obviously I don't visit their stores all that often right now.
I guess I will have to include some the next time we order stuff for safe pick-up and have a look at the packaging. :)
