  • User’s wishes aggregated to form new markets

    1. The origin of the name "CUUSOO" is the Japanese word "空想 (kuusou)", which means "to imagine and wonder about something unlikely to happen or exist".

      It was always someone’s dream:
      "To get on an airplane and travel around the world"
      "To go beyond time and place, and connect with ones love"
      "To have a robot clean up the room"
      Many things we do today daily were originally products of imagination that popped up in someone’s mind. "CUUSOO" is the hope for the future, and the source of the power which people have been innovating the society with. Ever since its foundation, CUUSOO SYSTEM has been creating mechanisms to "materialize wishes".

      We hope to be a force to materialize as many wishes of user’s. It is also our obligation to firmly connect supply and demand for corporations as much as possible by facilitating mechanisms.

      We are creating today, and will continue to create the future so that our CUUSOO will materialize one day.
