Tokyo Tower Completion Day

What Is Tokyo Tower Completion Day?

Every December 23rd is "Tokyo Tower Completion Day" (東京タワー完工の日, Tōkyō Tawā Kankō no Hi) in Japan. On December 23, 1958, Tokyo Tower (東京タワー) — a 333-meter steel lattice tower in Minato Ward, Tokyo — was formally completed, becoming the tallest structure in Japan and one of the tallest freestanding towers in the world at the time. Built primarily as a broadcasting tower to transmit television and radio signals across the Tokyo metropolitan area, Tokyo Tower became an immediate symbol of Japan's postwar recovery and modernization ambition.

Tokyo Tower: Symbol of Postwar Recovery

Tokyo Tower was constructed in just 18 months — a remarkable achievement that itself symbolized the speed of Japan's postwar industrial recovery. The tower was designed by architect Tachū Naitō (内藤多仲) and built from steel sourced partly from American military vehicles scrapped during the Korean War — a symbolic detail that transformed materials of war into infrastructure of peace. At 333 meters, it surpassed the Eiffel Tower (300 meters) in height while using one-third less steel, reflecting the engineering advances of the postwar era.

Broadcasting and Beyond

Tokyo Tower served as Tokyo's primary television and FM radio broadcast facility from 1958 until the completion of Tokyo Skytree (634 meters) in 2012. Though its primary broadcasting function has been transferred to Skytree, Tokyo Tower continues to operate as a tourist attraction and secondary broadcast facility. The tower's distinctive orange-and-white paint scheme (required by aviation regulations) has made it one of Japan's most recognizable landmarks, visible from across Tokyo and immortalized in countless films, anime, and photographs.

Cultural Legacy

Tokyo Tower appears in an extraordinary number of Japanese films, anime series, and popular culture works as a symbol of Tokyo itself — its illuminated silhouette against the night sky representing the city's energy and modernity. The tower has appeared in Godzilla films (as a target of monster destruction), romance dramas (as a romantic backdrop), and countless anime series set in Tokyo. Its role as a cultural symbol has proven even more enduring than its broadcasting function.

Fun Facts

• Color standards: Tokyo Tower's orange-and-white striped paint scheme is specified by aviation safety regulations requiring tall structures to be visibly marked for aircraft. The precise orange shade is "international orange" — the same color used for the Golden Gate Bridge in San Francisco.
• Valentine's Day lighting: Tokyo Tower offers special illumination for Valentine's Day, White Day, and various seasonal events — its position as a romantic landmark and urban icon makes it a natural focal point for Tokyo's calendar of illumination events.
