The Tower of wind in Tokyo is a man made island Japan that takes 30 years in the making. It is a ventilation facility of Japan that is also serves as a midway point between the Tokyo Bay Aqua-Line and that connects Kisarazu City and Kawasaki City. People normally see this facility only through a window while boarding on a plane or through Google satellite view. This Tower of wind in Tokyo is also known as the Kaze-no-to. Many are wondering if this facility is a government owned or is a secret den by somebody else. Well, whatever it would be, the only thing I see is that it is a great facility with a good purpose.
