This should be possible:
http://www.wolframalpha.com/input/?i=tokyo%2C+beijing%2C+Cairo%2C+Rio+De+janeiro%2C+Champaign+IL+
Use the show coordinate button
. But this usually takes longer time. The corresponding API call from within Wolfram Language is:
WolframAlpha[
"tokyo, beijing, Cairo, Rio De janeiro, Champaign IL ", {{"Path:CityData", 2}, "ComputableData"},
PodStates -> {"Path:CityData__Show coordinates"}
]
