Authorities in Fukushima are installing warning signs in English telling thrill-seeking tourists not to stop their cars or pose for selfies in areas that still have dangerously high levels of radiation.

Seven years after the disaster at the prefecture's nuclear plant, the government’s nuclear emergency response office has placed 26 signs along a 45-mile stretch of National Road 114 and a number of smaller roads in areas designated as “difficult-to-return” for local residents, the Asahi newspaper reported.

One road through the town of Namie was only reopened in September and is primarily used by construction vehicles and lorries removing contaminated waste and debris to landfill sites.

Motorists are able to access the roads, but authorities have installed signs after tourists were spotted getting out of their cars to take photos. Pedestrians, cyclists and motorcyclists are still banned from entering the restricted zone.

The signs read “No Entry!” for motorcycles, mopeds, light vehicles, bicycles and pedestrians, while others warn of “High-dose radiation area” and advise “Please pass through as quickly as possible”.
