Before the accident, their adult children used to help in the field as part-time farmers, but they had to abandon their fields due to the evacuation, and as a result they have ended up losing their connection with agriculture. Even the younger people I am talking about here, who might consider returning to engage in agriculture, will probably be in their 50s, so I would say most farmers will be 75 or older.

Hirano: So it sounds like even if the experimental planting succeeds, these farmers are not actually pursuing an operation to make a living. Like the elderly couples you mentioned earlier, these farmers really want to return home and as long as they can grow enough to feed themselves, they will be happy. They feel terrible about leaving the land they inherited from their ancestors unattended for such a long time. The decontamination work has been completed, and all the weeds in their fields have been pulled.

Now that their land is back to normal again, they probably want to at least cultivate it and harvest crops they can eat in the land their ancestors passed on to them. They moved back to their home as soon as the government took Odaka off the designated hazard zone in April The Nemoto family has been farming land here since the early 17 th century. Their neighbors and friends have not returned, and they think that they will not return. Photos by Yoh Kawano. Of course, I cannot say for sure that they have no intention of earning income by selling their produce. Speaking of rice produced through test planting, as long as it is certified to be safe, it is can be sold in the market.

It is true that the rice is tested on a bag-by-bag basis to ensure the radioactive cesium level does not exceed the limit, and the contaminated soil has been treated with zeolite. The deep plowing method has also been applied to the soil so that the upper layer soil can be replaced with a lower layer. In my opinion, however, some radioactive substances still remain in the soil.

It means it is possible that there are still some risks of farmers being exposed to radiation in their fields. Right now there is no technique that has been established to remove zeolite from the soil. The best way would be to scrape off the soil completely, but this would also remove the compost, which would probably affect soil fertility and crop growth. In fact, rice yields have decreased considerably compared to before the accident. So I guess we need to figure out how to deal with these problems associated agricultural land in the future.

Amaya: I believe it is very important to establish control measures to minimize radiation exposure to farmers. Suzuki: I also think the government needs to properly communicate the risks, educating farmers about the risks caused by radiation instead of giving them a go-ahead based only on whether or not radioactive substances are detected in their produce. For example, before the accident it was not uncommon for them to roll up their trousers and enter a rice paddy barefooted if they needed to fix some small thing. But now they need to be advised to avoid doing so because radioactive substances may still remain in the soil.

Although the level of airborne radioactivity has been reduced, it does not mean the substances have been completely removed. The radioactive compounds have been buried deeper in the soil by deep plowing and also remain with zeolites in the soil. Amaya: What zeolite does is absorb radioactive cesium in the soil, so it makes crops less likely to absorb cesium, but as long as zeolites stay in the soil, radioactive substances will remain in the soil as well.

Amaya: As far as I know, there is no way to remove zeolites that have absorbed radioactive cesium from the soil selectively or efficiently at low cost. Amaya: Some researchers have been trying to develop technology to remove radioactive cesium from zeolites. In fact, it is possible in principle to dissociate cesium absorbed into zeolites with acid, but you would need a lot of equipment to treat a large amount of soil, and a facility to store radioactive cesium.

The cost for all of this might pose a big problem. Also during the process of dissociation, mineral nutrients in the soil are likely to be removed, so it might also become a problem when it comes to growing crops. It sounds like it may be extremely difficult to revitalize agriculture, which had been the mainstay of Fukushima. First of all, we need to figure out how to solve the problem of manpower. I think we can recruit people, but as I have mentioned before, those who are interested in engaging in agriculture and actually have the agricultural skills to do it are mostly elderly people in their late 60s and 70s.

It will be hard for them to remain active for the next 10 or 20 years. So the future of agriculture is an open question. Hirano: Namie has wonderful mountains and ocean, and before the nuclear accident, it was known as a place where you could harvest not only rice but any food you want. It used to be surrounded by rich, beautiful nature. According to surveys of city dwellers before the accident, Fukushima was always one of the most ideal places to move to enjoy the country life in retirement.

In your view, what had most attracted people to Namie before the disaster? Suzuki: Well, to put it briefly, a lot of it is the rustic atmosphere. We have traditional crafts like Obori Soma ceramic ware, and both fishery and forestry were active. There were farmers who grew pears and other fruit.

Rice, fish, fruits, seasonal foods like mushrooms and vegetables— all these were within our reach. Namie was a comfortable and easy place to live. There is no doubt that the nuclear industry was one main factor that made this town prosperous. All the regions throughout Japan where nuclear power stations were located, were very poor. There was nothing to develop. But remember, we were always lectured with the myth of nuclear safety, and I was taught it since I was little. We visited the nuclear energy information center on a social studies school trip and learned about how it would work and how beneficial it would be, like how it could create energy at a low cost.

I do not recall any discussion about radiation at all. It is also true that we had a low unemployment rate in this town because there were a quite a few people engaged in nuclear power-related work. Our tax revenue also had been going up, and the nuclear industry had promoted our local economies significantly. So economically the town and the industry maintained a mutually beneficial relationship. Namie High School before the Nuclear Disaster. Hirano: So residents here had a very positive impression of the economic effect brought by the nuclear industry?

Hirano: So while the safety myth had been accepted widely by residents, neither the central government nor TEPCO had explained anything about nuclear related risks. We were told that accidents could not happen. Nothing like that at all…. So I think probably not at all. This must be true for other communities with nuclear power plants nationwide. Hirano: I agree with you. My hometown is close to Tokai-mura, and I heard the same thing from residents there, as well.

This is probably how the safety myth spread through all these communities.

The residents were told how it would bring positive economic effects and significant wealth to their community. This was how they came to accept the nuclear power plants in their community. Was it the same in Namie? Suzuki: Yes, I think it was the same here. I am 56 years old, and I was 50 at the time of the accident. I believed what they had told us. I did not even realize that a cooling system failure could cause the kind of situation that it did.

So at the time of evacuation, I imagined that the accident at the power plant would lead to an explosion, that is, an explosion like an atomic bomb. That was the image I had then about the accident. However, at the time of the accident, plant workers I talked to said that the loss of power supply and the failure of cooling system in one unit would cause problems with all four units.

They all said that. Obviously those who were engaged in the plant work knew so much more about radiation, such as the limit of radiation exposure, since they worked in a strict radiation-control environment. I am sure they had been educated well through numerous lectures about radiation. I have a feeling that only a handful of officials in local government had knowledge about radiation at that time.

I gradually learned all about how much exposure we received, and about radioactive substances Cesium , , Strontium, etc. I came to learn these things after the nuclear disaster. I had no knowledge whatsoever before then. Hirano: Let me ask you some specific questions.

You mentioned that the industry stimulated the local economy. In fact, my uncle also ran a small subcontracting company, which was about two or three steps down from the general contractors. Suzuki: I think many of them did. Hirano: I would like to ask about the return policy.

Suzuki: My feeling is that right after the disaster, the central government was willing to listen to us and to try to help with whatever we needed, but recently I feel that they have turned everything toward lifting the evacuation orders. More money? The government should just contribute money — this was the feeling I got. I know the central government hires many officials as needed, so it is hard to deal with our request for more people to handle the extra work related to the evacuation.

However, it is easier to provide funds to the disaster-stricken areas. Here we thought that victims of the Great Hanshin-Awaji Earthquake of must have resumed normal lives after a few years of living in temporary housing. Hirano: What the media has been saying is that for Namie, in particular, after lifting its evacuation orders, full-scale reconstruction can begin. I feel that what the Japanese government is trying to do is to send the message that the nuclear crisis in Fukushima has been finally settled. The government believes that it is necessary to do so in order to create an image of Japan rising like a phoenix from the ashes at the Tokyo Olympics of Suzuki, how do you feel about this sense that the government has conveyed that the situation in Fukushima is now under control, that reconstruction has been going well, and the return policy has been successful?
