Roppongi Hills will be lit up brighter than ever this holiday season for "Artelligent Christmas 2005." Until Dec. 25, Keyakizaka Dori will be covered in the glow of blue and white lights while the main entrance to Roppongi Hills, 66 Plaza, will be lit up by its "Dramatic Crystal" illuminations that aim to create the image of falling snow.

At Roppongi Hills Arena, the Irish choir ensemble Anuna will perform as part of the "Holy Night Concert 2005" (Dec. 21, 23-25 at 5 p.m. and 7 p.m.). The concerts are free (no tickets required).
