Tokyo Tower, Japan

When Gustave Eiffel received criticism over the appearance of his 1889 tower in Paris, he simply replied that he’d done the maths and the shape required to withstand the physical forces bearing on the structure was also the best aesthetic solution to the design.

Indeed, the shape has proved impossible to improve.  The canny Lancashire proprietors of the half-size version in Blackpool built a three-storey entertainment complex around the legs, with a circus at its base.   Sir Edward Watkin, the British railway magnate, began an abortive giant version next to the Metropolitan Railway at Wembley, where the stadium was later built.

Over thirty replicas – some closer to the original than others – have been built:  https://en.wikipedia.org/wiki/Eiffel_Tower_replicas_and_derivatives.

Of all these tributes to Eiffel’s design, there is no more sincere example of flattery than the Tokyo Tower, built in 1958, at a time of recovery from the devastation of war, to provide broadcasting transmitters for radio and television.

It stands on top of a hill in the Shiba-koen district, and has always been distinctively painted in white and international orange to satisfy the requirements of air safety.  In 1987 the original outline lighting was replaced by a more flexible floodlight system by Motoko Ishii, varying the customary colours, white in summer and orange the rest of the year,

At 333 metres, it was for long the tallest structure in Japan, and exceeds the height of the Paris tower by precisely thirteen metres.

At the base is a visitor-reception building, FootTown, which is not integrated into the structure as in Blackpool.  It’s possible to ascend to two observatories, at 150 and 250 metres respectively.  Indeed, those who wish can climb 660 steps to the first observatory by a staircase from the roof of FootTown.

The Tokyo Tower is not tall enough to provide full digital coverage across the region, but it will continue to carry FM transmitters and act as a limited digital back-up, and its status as a landmark and a tourist attraction seems secure.
