Falcao gives Colombia win in Japan, SKorea beats Bolivia
Radamel Falcao converted a second-half penalty after a handball by Takehiro Tomiyasu, to give Carlos Queiroz a win in his first match as Colombia coach.
Colombia earned a measure of revenge for losing to Japan in the World Cup pool stage last year, although both teams advanced, and Queiroz also earned some revenge as his eight-year tenure in charge of Iran was ended by Japan in January in the Asian Cup semifinals.
Japan failed to find the target despite 17 attempts in its first game since losing the Asian Cup final to Qatar.
Japan, joining Colombia at the Copa America in June in Brazil, gets another taste of South American action on Tuesday against Bolivia.
South Korea struggled to make its domination count against Bolivia. Son Heung-min wasted several chances before a header by Lee Chung-yong scored the winner with five minutes remaining.
The Koreans welcome Colombia to Seoul on Tuesday.
