"Ad trains" may hit Tokyo as early as the fall as the Tokyo Metropolitan Government moves to lift its ban on city trains carrying exterior advertisements, it was learned Thursday.

However, the move is likely to raise the ire of many who fear the deluge of advertisements on such trains will only add to visual pollution in the city.

The plan to allow railway operators to plaster the bodies of their trains with advertisements will be approved at an advisory panel meeting scheduled to be convened in early September, according to officials of the city planning bureau.
