If the Democratic Party of Japan gains power in Sunday's Lower House election, it plans to propose to the United States revising the bilateral Status of Forces Agreement to include a clause on dealing with environmental pollution or destruction at U.S. bases in Japan, DPJ members said Wednesday.

The intended clause is aimed at allowing the central and local governments to carry out on-site inspections of the environmental pollution or destruction, and obliging U.S. forces to restore the situation to the original state, they said.

The DPJ plans to urge the United States to accept the clause, as the SOFA between the United States and South Korea already has one, according to party members.
