Rio de Janeiro's hosting of the 2016 Olympics has divided public opinion in Brazil, where political and economic crises have put the games under scrutiny like never before.

But after a seven-year buildup in which everything that could possibly go wrong did, the Olympics have finally arrived in Brazil's second-biggest city.

According to organizers, around 80 percent of the Rio Games' 6.1 million tickets had been sold as of Aug. 1, and The Japan Times caught up with visitors to the main Barra Olympic Park to gauge the mood.
