Japan to reuse Fukushima cleanup soil in Miyagi, Saitama prefectures

The Japanese Environment Ministry has announced plans to repurpose soil collected during decontamination efforts near the Fukushima Daiichi nuclear complex at government branch offices in Miyagi and Saitama prefectures. This marks the first reuse of such soil outside Tokyo, with previous successful deployments at 12 sites in Tokyo since July last year, including the prime minister's office in the Kasumigaseki district.

As of July, roughly 14.46 million cubic meters of removed soil and other waste have been stored at an interim facility near the nuclear plant. The nuclear power plant, severely damaged by a 2011 earthquake and tsunami, experienced fuel meltdowns in three reactors, releasing radiation into the environment. The government aims to recycle 75% of the soil with low radioactivity levels for public works, but only a tiny fraction - just 2 cubic meters - will be used in Sendai and Saitama.

While the exact timing is still undecided, the soil will be employed in planting projects at government buildings in Sendai's Aoba Ward and Saitama's Chuo Ward. Officials from both prefectures have expressed concerns and requested transparency regarding monitoring test results and resident understanding before proceeding. Okuma Mayor Jun Yoshida and Futaba Mayor Shiro Izawa, whose towns house the interim storage facility, eagerly anticipate the move's contribution to final disposal outside the prefecture.

The government plans to further expand the reuse of soil in branch offices across Japan to mitigate the overall volume of soil that eventually needs to be managed. A roadmap for final disposal outside Fukushima Prefecture, released in August last year, outlines the selection of candidate disposal sites between 2030 and 2035.
