Some very cool concept phones from Japan

I just love seeing concepts from all over the web and there is an abundance of concepts. But rarely do I see Japanese concepts. Why is everything Japanese just cooler to me? Anyways these concepts are not pics or renderings. They were actually built and put on display. The concepts were presented by the Japanese mobile operator AU KDDI and like all things Japanese...they are to the extreme. The first concept is a relatively large clamshell and it has no visible keys...instead it has 3 huge touchscreens which react and change according to what you do. The second concept is a phone disguised as a pebble and it's whole surface is the display. The other concepts are pretty self explanatory. Enjoy the pics!
