Rio Olympics closing ceremony welcomes Japan's Prime Minister Shinzo Abe

He then morphed into Super Mario, rushed into a green pipe taken from Doraemon's 4D pocket, drilled his path and came out from a giant pipe right at the center of Maracana Stadium.

He was loudly applauded by the crowds. His appearance was in contrast to his serious character, which made it a surprise that quickly garnered praises. He did close the parade well - holding a glowing red ball as the surroundings faded to dark - reminding us of the rising sun flag.
