Uighur residents in Japan and their support organization have been campaigning to raise awareness about nuclear tests conducted by China in the country's northwestern Uighur autonomous region, saying they have been harmful to people's health.

On Aug. 6, the anniversary of the atomic bombing of the city of Hiroshima by the United States, some residents and supporters distributed leaflets to visitors of the Peace Memorial Park in the city's Naka Ward.

Ilham Mahmut, the 42-year-old leader of the Japan Uyghur Association, said that since the Chinese government claims it does not conduct research (in the area), it remains unknown what exactly has been taking place. Ilham said the group would like to step up its campaign in Hiroshima to press authorities to shed light on what has been happening.
