TOKYO: Japanese autho­ri­ties carried out an inspection of a US military base in Tokyo on Friday, a government spokesman said, after being informed by the American side of a chemical leak.

Japan’s probe at the Yokota air base followed a US notice two months ago that water containing PFOS — classified by the World Health Organisa­tion as “possibly carcinogenic to humans” — had spilled from the site.

PFOS is part of a large group of man-made chemicals known as PFAS, sometimes called “forever chemicals” because they do not degrade easily, experts say.

The US military infor­med Tokyo in October that the PFOS-laced water had leaked from an area of the base where a fire-fighting drill was being carried out, Japan’s deputy chief cabinet secretary told reporters.

“This inspection was realised in response to the fears and concerns harboured by local residents, and we will continue to work together with the US side,” Sato said.

Officials from the defence ministry and Tokyo’s metropolitan government visited the site on Friday, he said.

“PFAS is a shared concern applicable to military and civilian industrial activities across Japan regardless of nationality,” the Yokota air base’s public affairs office said in a statement.

“We remain committed to protecting the health of our personnel, their families, and the surrounding communities in which we live and serve,” it said, adding that it will observe all relevant agreements and obligations and closely coordinate with the Japanese government “towards sustainable solutions”.
