We won the championship of the TechCrunch Hackathon Tokyo 2013 as the team "Wondershake” before I arrived in Sapporo. This battle is so hard because we must plan and make new service in only 24 hours. And it has a rule that we should use one of the APIs that supporting companies offer.

Our service [Fuwari] is a mood application that users can share by listening to music. We used Gracenote,Inc.’s API . We completed a really high quality app because most people cann’t believe that we made it in 24 hours only. People from Gracenote,Inc likes our application and us. Honestly, that made me happier than winning the chanpionship. lol
