From phones that can tell who their owner is using facial recognition, to phones that let you buy things over the counter by simply touching a sensor, the list of features available on Japanese phones is practically endless.
Check out some of this year's highlights -- including a phone you can dunk in the bath, a phone that can tell the mood of a text message and even one that usestechnology.
First up is the Fujitsu F703i (pictured) that can impressively be submerged in 1m of water for 30 minutes. It also comes with a relax mode that makes the handset play sounds and glow with colours chosen by a colour-therapy expert. A perfect phone for anyone who likes to unwind in the bath.
