'We are currently suspending imports as a precaution,' said Ms Mitsue Kondo, a food safety official at the health ministry.
Japanese authorities are also checking with Irish officials about the contaminated meat and may recall Irish pork products, she added.
Ireland on Saturday said it was recalling all pork products made in the country after the discovery of dioxins, which may cause cancer, in slaughtered pigs thought to have eaten contaminated feed.
Ireland is a major exporter of pork, with Britain by far the biggest market followed by Germany, France, Russia and Japan.
But less than one per cent of Japan's total imports come from Ireland, according to the agriculture ministry. -- AFP
