The National Association of Commercial Broadcasters in Japan Radio Committee is running the "Radio de Iu Tatta" campaign, a unified effort by 101 commercial radio stations. They are currently accepting messages (until March 31).
This campaign leverages radio's unique power to engage listeners. It invites people to share messages they often think but rarely voice—messages that could improve society—via Twitter or a dedicated website. These messages are then converted into artificial voices and "retweeted" on the radio. It's a dynamic challenge where radio itself uses the medium to convey the thoughts of ordinary people.
Messages are currently being widely solicited from the public. Details here (Radio de Iuttatta Official Homepage).
