Around seven years ago, I enjoyed a nice night in Tokyo, opposite the Tokyo Tower. I climbed the lighthouse and took pictures of the city. These last three are taken by the banks before my cruise - near Osaka and Yokohama. The ship had undocked and was going to the next unknown destination. The Tokyo Tower is a popular landmark in the city and is located in the Shiba Park in Tokyo, at a height of close to 332.6 metres high. It is generally used to transmit waves for TV and radio while also sending JR train stop signals whenever a major earthquake occurs. There are other instruments available as well, including a wind direction and speed measurement device, temperature measurement and a navigation mark.
