TOKYO—Japanese Olympic gymnast Kohei Uchimura may be a record six-time world champion, but he won’t be encountering much success in his Pokemon Go efforts after running up a huge roaming bill in Rio.

Uchimura was stunned to receive a 500,000 yen ($4,900 U.S.) mobile phone bill after playing the popular augmented-reality game, Kyodo News Agency reported Tuesday.

Thankfully for him, his Japanese carrier service agreed to reduce his bill to a 3,000 yen ($30) daily all-you-can-use contract, Kyodo said.

Uchimura is the reigning gold medallist in the men’s all-around competition, and has said he is just as committed to a Japan team gold in Rio de Janeiro as he is to the personal title.

Nikkan Sports newspaper predicted “Uchimura may not get any Pokemon, but he will surely get gold.”
