To help quake- and tsuami-damaged areas rebuild, the Tokyo Metropolitan Government said Thursday it is offering to store about 500,000 tons of debris and waste from Iwate and Miyagi prefectures for three years.

The amount of debris in the disaster zones is so massive and regional disposal capacity so low that it is hampering with efforts to rebuild.

Tokyo intends to approve the plan with Iwate on Friday, while the agreement with Miyagi is pending.
