The Doki Doki Majo Shinpan "touching pillow"
It's as big as a child, and even boasts a variant model: a pyjamas version. So creepy.
The pillows provide your hands with something to do while relaxing. It's probably a very nice head rest as well.
Touching Pillow can give you some real feeling too
I don't think the Japanese are weird or creepy though. Everyone is messed up a little bit. Some more than others.
