We visited a debris storage site in Ishinomaki City Miyagi prefecture
Due to clean up delays the piles had grown to more than 20 meters
According the environment ministry the disaster left behind 4.64 million tons of debris in Ishinomaki
Without outside help it would take more than 80 years for the city to clean it all up
Buried in the piles were a wide variety of everyday items
The bits and pieces are sad reminders of destroyed lives
This pipe lets out the heat
Carbon monoxide mercury sulphide and methane are being produced inside
The fermenting debris produces gas and accumulates heat
If excess heat remains trapped inside the debris can burst into flame
25 fires have broken out at debris storage sites in Miyagi prefecture
Massive outbreaks of flies were reported in summer
Why has the clean up of the debris made no progress more than a year after the disaster
We decided to find out
The disaster produced 20 million tons of debris
The largest volume ever is hampering efforts to rebuild affected areas
Factories remain in shambles and there seems to be no end to the human exodus
Five years or ten years I probably won't be around until it's all cleared up
I'm worried the whole town will disappear
No radioactive debris
Efforts are under way to dispose of the debris outside areas hit by the disasters
Such plans are met with strong protests by residents worried about radioactivity
You say it's safe but we're not convinced
We won't accept it
What's more debris that's washed out to sea is now drifting on the Pacific Ocean
Some has reach US and Canadian shores and begun causing serious problems
Even a 20 meter long floating dock made it to the other side of the Pacific
This would be some of the debris
We're finding these on the outside coast everywhere now which we never found before
We don't know how we're going to clean it up
Last years tsunami left more than 18 million tons of debris in it's wake
Disposing of the remains is proving to be a major and costly problem
The central government hopes municipalities will help with the clean up but few have stepped forward
The city of Ishinomaki in Miyagi prefecture has the largest amount of debris among all the disaster regions
About five million tons
Those piles pose a problem
The temperature inside this pile is 80 degress Celsius
Last August one of the piles caught on fire
The government has been struggling to transfer debris to temporary storage sites
Only half of the debris in Ishinomaki has so far been tackled there's too much and no place to store it
Temperatures will rise in summer and flies can transmit infection
I don't think we can proceed with reconstruction or even dream of the future as long as debris remains
The government aims to dispose of all the debris by March 2014
Part of it's disposal plan would see some municipalities around the country accept 2,500,000 tons
So far six local governments have agreed but they are only willing to accept 43 percent of the target amount
Governments are reluctant to accept debris over concerns of radioactive contamination
Assembly members visited from Aichi prefecture to see a disposal facility
They are hoping to reassure sceptical residents in Aichi
That's where hazardous substances are broken up into small particles and are sucked up
and what comes out is steam
People in Japan are critical of the slow disposal pace
They say the government is not releasing information on the safety of the debris quickly enough
The government in October set radioactive safety limits at between 240 and 480 becquerels per kilogram after consulting international organizations
Officials in Aichi are considering whether to accept the debris
The safety standards are not trusted by the people in Japan
Aichi prefecture will set a stricter standard than the national one
The residents of Aichi are not as accepting about taking debris as prefecture authorities and local assembly members
A Toyota factory in Tahara city is one of the candidate sites that government says will accept debris
Masanobu Nagata heads a citizens group that is campaigning against accepting debris
He worked as a radiation technologist for 25 years before becoming a farmer
Nature still exists here and I feel the potatoes we grow taste better
Joined by like minded citizens Nagata continues to study radioactive contaminants from the debris
We have to protect our children
We shouldn't let our town accept the debris without having further confirmation
The safety limits sharply deviate from waste disposal standards set in the past
They will allow contaminated material to be moved around the nation and destroy Japan's beautiful nature
One year after the March 11 disaster, fears of radioactive contamination are keeping local
governments from agreeing to accept debris for disposal
This has left the government in a position where it may not be able to live up to it's pledge of completing the clean up by 2014
NHK has learned that some contractors have failed to pay a special allowance to workers
who remove radioactive fallout from the Fukushima nuclear accident
Japanese government has hired major construction companies carry out the decontamination
The actual work is performed by subcontractors
The government pays a risk allowance of 110 dollars per day in addition to a daily wage to people who work where there is high radiation
Two subcontractors in Fukushima city did not pay the allowance
Workers were promised 110 dollars per day with free accommodation and meals when they started their jobs in mid 2012
They say their employers did not mention the special allowance
Between November and December subcontractors gave workers a new document about working conditions
The allowance was paid on paper but the daily wage was cut to 67 dollars with accommodations and meals deducted from payment
It seems as long as this system of cheating workers continues the less people will want to do this job
The subcontractors asked workers to sign the document as if it were the original but then employers admitted it was a fake
The workers say their employers tried to hide the nonpayment of risk allowance
Japans nuclear regulators discussed how to safeguard nuclear power plants against accidents similar to Fukushima Daiichi
They drafted new safety standards for nuclear facilities
They have proposed new filtered vents for the power plants
The vents would reduce pressure in containment vessel and filter contaminated steam
Workers struggled to control the pressure in Fukushima reactors after the 2011 tsunami
Watchdog officials consider stand alone facilities to cool damaged reactors and inject water from safe distance
Proposals will face a public review
Japanese government is investigating workers involved in the nuclear clean up in Fukushima
Some are endangering citizens by dumping radioactive material
Contractors have been working on the clean up since July
They have to seal and store radioactive material
But officials have been looking at reports that some dumped soil and vegetation in rivers
and didn't collect the water they used
Officials question workers to find out if others are breaking the rules
Violators face 5 years in jail or fines of 100,000 dollars
Environment ministry is looking for advice on how to store dirt and contaminated debris
contaminated by 2011 accident
Workers have been removing topsoil to decontaminate the area
The government plans to construct intermediate storage facilities in three towns near Fukushima Daiichi plant
The debris will be kept there until final disposal sites are built
Some residents are concerned about high levels of radiation
Environment Ministry is assembling panels of experts to confirm the safety of the plan
Geologists will check the ground under the site to make sure it's stable
They will also give advice on the structures and facilities as well as safety measures
Another panel of experts will discuss how to conserve the environment around the sites
One year on and Mrs. Ahashi is taking her children to the doctor
They have been sick frequently over the last 12 months
Nosebleeds diarrhea sore throats
Symptoms that disappeared when they went away but returned when they came back to Fukushima
The eldest one went away during the summer
When she came back in November she had mouth blisters
From mid December when she went away again the blisters went away
On a sheet she lists the symptoms
Before the tsunami she says the kids were all in very good health
Now they're picking up every little bug going around
