Dubbed Ao no Dokutsu, meaning blue cavern, this breathtaking illumination was a huge hit when it made its debut along the Meguro River back in 2014. The now annual event made a comeback in Shibuya a couple of years ago, where it will again bathe the tree-lined walkway leading to Yoyogi Park in a fantastical blue glow this holiday season until Christmas Day.
Stretched out for 900 metres along Koen-dori and Yoyogi Park's Keyaki event space, this fantastical illumination is made up of around 600,000 blue LEDs. The lights are also reflected off the ground to create an immersive experience.
The illuminations take place daily between 5pm and 10pm.
