IDEASKETCH, Inc. launched the “AR HAKKEYOI” app on which you can watch a sumo bout and share it on SNS.
Download the app, point your camera at something circular, which will be used as a sumo ring, and then two wrestlers appear in the ring to start a sumo match.
Take a capture, share it on SNS and enjoy watching sumo together!
