After a hiatus of two years, the Blue Cave relaunched in Shibuya in 2016, originally a Meguro River spectacle in 2014.
If you walk from Shibuya crossing to Koen-dori between 5pm–10pm you will see the start of the Ao no Dokutsu (Blue Cave). Walk further up the hill to Yoyogi Park to see the spectacular Blue Cave. It effortlessly envelopes the crowds, with a striking blue haze.
Approximately 600,000 lights are used in the 800-meter display.
In 2017, I visited on the day it snowed in Tokyo. The air was crisp and the puddles made for some great reflections.
