In addition to events and anniversaries, Tokyo Tower's special light-up "Diamond Ver" is basically held every Saturday for 2 hours only from 20:00 to 22:00.
I hear that the total number of lights shining from the frame to the outside is 276, and that the 17-tiered light hierarchy is variable to seven colors, each with a message for each color.
On September 2nd (Saturday), "Planet Green" lights up.
It is a blueish green lighting based on "green of the earth".
This is why the message "Earth and Peace" is included.
From the Sumida River Terrace in Kachidoki to the Tsukiji Market, Diamond Ver Planet Green, which gives a sense of peace, shines.
