Belarusian sprinter Krystsina Tsimanouskaya took refuge in Poland on Wednesday after refusing to return to her homeland.
The athlete said her coaches were angry with her last Sunday for her criticism of Belarus and ordered her to pack and go to the airport. She refused to board a flight home and sought protection from Japanese police.
Poland is noted for being critical of Belarusian President Alexander Lukashenko and the country has harboured many activists from Belarus.
Poland has granted the athlete and her husband humanitarian visas.
