Local governments in the Tokyo area are vying to host the world's tallest broadcasting tower in hopes of attracting tourist revenues.

They began intensifying efforts in December, when terrestrial digital broadcasting was launched in three major cities, prompting NHK and five commercial broadcasters in Tokyo to agree to promote a project to build a new 600-meter-tall Tokyo Tower.

Shop owners in Taito Ward launched a petition to push construction of the new tower either along the Sumida River or in the neighborhood of the popular Sensoji Temple in Asasuka.
