Tokyo laboratory to handle world's deadliest viruses including Ebola after decades of local opposition

A research lab in a Tokyo suburb will start handling some of the world’s deadliest viruses for the first time, officials said, after local opposition blocked it for decades.

Japan has no active maximum level-four biosafety labs so the move will bring it in line with other G7 nations – there are about 40 such sites worldwide including some run by the US Centre for Disease Control and Prevention (CDC).

The Tokyo lab was built in 1981 and designed to handle the most dangerous known viruses, requiring scientists to wear full body suits with oxygen intakes to avoid contamination.

But local opponents feared exposure, arguing that the neighbourhood with schools and other community buildings would be at risk.

In response, the site was downgraded to a level-three facility where scientists can work with certain microbes such as the Middle East Respiratory Syndrome (MERS) virus and the bacteria that causes tuberculosis.

The decision to boost it to the highest biosafety level came as Health Minister Yasuhisa Shiozaki signed an agreement with the mayor of the Musashimurayama suburb.
