This year, the seasonal illumination around the Roppongi Hills complex can be mainly found along Keyakizaka Street in the back of the tower.
Shibuya Ao no Dokutsu
Cancelled in 2020
The main venue of the Ao no Dokutsu illumination (lit. "blue cave") is the 250 meter long pedestrian street in front of the NHK headquarters in Shibuya. The zelkova trees that line the street are covered in blue LED lights and a reflective sheet is laid out in the center of the street. Blue is cast everywhere and one can easily imagine themselves to be in a blue cave.
Meguro-gawa Minna no Illumination
Actual illumination cancelled in 2020; only an online event is held
The trees along the Meguro River between Gotanda and Osaki stations on the Yamanote Line are decorated in pink LED lights to resemble the cherry blossoms. The illumination spans a length of about two kilometers, making for a very pretty stroll along the riverside.
