In Japan, the Brazil-themed illuminations decorated the Tokyo Metropolitan Government Building while in South Korea, the N Seoul Tower was lit up for the occasion.

Other cities lighting up their buildings include Mexico City, Doha, Buenos Aires and Athens.

The Rio de Janeiro games will run from August 5-21.
