One Japanese rice farmer is now struggling with his life.  Nobuhiko Kurosawa owns a rice farm with a proud history of more than 400 years.  At a time in the past, his rice was awarded as “the most delicious rice in Japan,” and well-received, both at home and abroad.  However, since his farm is located northwest of Fukushima, he could not avoid facing a colossal drop-off in his rice sales as people expressed concerns over the safety of rice grown in Northeastern Japan after the explosions at the Fukushima nuclear power plant.

In order to prove the safety of his rice, he had his farm soil and his brown rice tested at inspection facilities.  He was relieved to learn that radioactive cesium was not detected in his brown rice, but at the same time, he realized the difficulty of restoring his customers’ trust and his pristine reputation that were lost.

This documentary features a rice farmer who views radiation as his invisible enemy while struggling to regain consumer confidence in his rice.

 被污染的土地

日本有一位稻农孤军奋战。他就是黑泽信彦。他出生于400年以上承袭下来的稻米农家，他种的稻米曾经被誉为「日本第一好吃」，广受国内外的瞩目。但是他的农田位于福岛县的西北部。核电站事故以后，消费者对东北地区稻米安全性的不安逐渐蔓延，使之黑泽先生的稻米销售量也一瞬间直线下滑。

为了证明稻米的安全性，他将自己农田的土壤和糙米依赖于检验机关调查。检查结果从糙米中没有验出铯元素，可是黑泽先生这时才明白要恢复被失去的信赖是多么地艰难。

这部纪录片追踪看不见的敌人即与放射能一边奋战，一边为恢复稻米的信赖而奔走的农家的执着心。
