During the whole month of December, Koen Dori is lightened in blue from 17h00 to 22h00. This is a project that started in 2014 in Meguro but moved last year to Yoyogi. The best location is to be at the entrance of Yoyogi park on the side of NHK building just before 17h00 and be surprised by the blue light going on suddenly, it is truly amazing!. then walk along this 250m totally covered with LED lights. the avenue takes you down to Shibuya in a lighter version
This concept also exists across Japan in Sapporo, Sendai, Nagoya, Fukuoka, Hiroshima and Osaka.
