Nihondaira Digital Tower, Television tower in Kusanagi, Shizuoka, Japan.

The Nihondaira Digital Tower is a steel lattice mast on the Nihondaira plateau in Shimizu-ku, Shizuoka, built jointly by NHK and six commercial broadcasters as the main transmitting station for Shizuoka Prefecture's terrestrial digital television. Its silver-grey structure carries medium-intensity white aviation obstruction lights instead of the red-and-white striping used on the neighbouring analog masts. A viewing corridor of the Nihondaira Yume Terrace, opened in 2018, circles the tower.

Taisei Corporation completed the tower in 2005 as part of Japan's transition from analog to digital television broadcasting. This project represented a major step in modernizing the broadcasting infrastructure of Shizuoka Prefecture.

The tower's silver-grey steel frame uses medium-intensity white aviation obstruction lights instead of the red-and-white striping on the neighbouring analog masts, a choice made to fit the Nihondaira landscape; it won the 2005 Good Design Award and the Shizuoka Construction Industry Association's Excellence Award. Since 3 November 2018 the surrounding Nihondaira Yume Terrace observation corridor has let visitors walk around the base.

The tower sits on elevated terrain in Kusanagi and is accessible by local roads. Visitors should note this is an active broadcasting facility that may have access restrictions.

From its elevated position the tower offers views of Mount Fuji and Suruga Bay across the landscape. This location makes it a notable geographical reference point in the Nihondaira area.
