Last year's TechCrunch 50 buzz, Tonchi Dot officially launched its AR (Augumented Reality) application "Sekai Camera" on iTunes Store. They have launched its service on Softbank (iPhone carrier in Japan) on Sep. 17. Looks like they are showcasing it on Tokyo Game Show, so expect more info about it!!
I met Mr. Iguchi, founder of Tonchi Dot a few months ago and was QUITE impressed, not just by their technology but also his/their level of energy and concept. Up until now, there have not been a successful software/application venture from Japan on global scale, and I hope they are going to be one of the firsts.
