The 400m-long Keyakizaka Street next to the Roppongi Hills shopping centre is lighting up with 800,000 sparkling white and blue LEDs until Christmas Day. From the pedestrian bridge near the Roppongi Hills Arena, you'll get a stunning view of the trees covered in shimmering lights, with Tokyo Tower in the background, from 5pm to 11pm daily.
While you’re in the area, make sure to drop by the Mohri Garden, a Japanese-style green space sandwiched between Roppongi Hills Mori Tower and the TV Asahi building, which is illuminated with blue lights from November 6 to 18. There’s also a bouquet-inspired illumination at 66 Plaza to commemorate Roppongi Hills’s 20th anniversary, with 200,000 LED lights illuminating the surrounding trees.
