Fuji TV Headquarters

There is an interesting geometric resemblance between the Fuji TV Headquarters and the lesser-known Hitachi Civic Center (see photos 4 and 5). The two buildings were constructed six years apart — Fuji TV in 1996 and the Hitachi Civic Center in 1990. What makes this even more intriguing is that there are no direct references suggesting that the Hitachi Civic Center influenced Fuji TV’s design. However, could it have been a source of inspiration for Kenzo Tange, the architect of Fuji TV’s headquarters?

The Fuji TV headquarters is located on the artificial island of Odaiba in Tokyo Bay and has been an iconic landmark for nearly 30 years. Its futuristic design resembles a spaceship that has landed in the bay.

The building consists of two main blocks, connected by three "sky corridors" — enclosed pedestrian bridges. These corridors are supported by steel columns, enhancing the structure’s earthquake resistance. Between the blocks, a massive titanium-clad sphere called "Hachitama" is suspended. The sphere has a diameter of 32 meters and weighs 1,200 tons. Lifting it into place was a complex engineering challenge, taking 9.5 hours. Initially, the sphere was assembled on the 7th floor, balanced horizontally, and supported by three beams. It was then lifted to a height of 123 meters using hydraulic jacks, moving at a speed of 5 meters per hour to reach the 25th floor.

Inside the sphere, there is an observation deck and a café that visitors can access. Interestingly, the Hitachi Civic Center is also open to the public — it houses a science museum and an observatory.
