With a crew of seven including himself, director Makoto Sato spent three years embedded within the small communities along the Agano River capturing a disappearing way of life but also the resilience of the elderly residents many of whom are unrecognised victims of Minamata disease caused by the chemical discharge from the Showa Denko chemical plant.
“Kids don’t care about our rivers and our mountains” 80-year-old Miyae Hasegawa reminds her husband on the phone to their oldest daughter as she once again tries to convince him that he’s too old for the intensive labour of farming their rice paddies. Like many, the Hasegawas’ children have fled the rural village for more comfortable lives in the cities while their parents attempt to preserve their traditional way of life. “Gradually we realised that these rice paddies were their entire existence” the film crew later reflect, almost pitying them as they witness these quite elderly people bent over still harvesting the rice in their 80s while discovering on trying to help them that the work is far more difficult than they could have imagined not, presumably at least, very used to physical labour at least of this kind.
Even so, “humans are cruel” Yoshio Hasegawa laments to his son having had too much to drink, somewhat ambivalent in having become proficient at catching salmon by hook. After all, the fish are only trying to live but humans keep pulling them out of the water. Later we watch him hook fishing at the river, the camera cutting to black as another man takes a fish he’s caught on a hook and bashes its brains in. Ironically, as the voiceover explains, Miyae had worked on the construction of the Kanose hydraulic dam in the 1920s which later powered the fertiliser plant which then became Showa Denko. After completion of the Yogawa dam in 1963, the fish ominously disappeared from the river and with them the traditional practice of fishing by hook.
Many in the small communities along the water had welcomed the arrival of modernity that the Showa Denko plant had represented, some still remaining loyal to the company despite knowing what they know unable forget that they had benefitted economically from the factory’s existence. Ebana, meanwhile, who had worked for Showa Denko for 34 years now runs regular patrols of his local area monitoring for the possibility of landslides behind the plant. He was the only employee to sue Showa Denko as a victim of Minamata disease though the company’s attempt to transfer him out of the area when he did so put others off following his example, as did the degree of animosity towards him as others feared for their own economic stability or resented him for betraying his employers. Though the chemical emissions from the plant which flowed into the Agano have been acknowledged as the cause of the disease, the government introduced increasingly strict criteria for official recognition as a Minamata victim leaving many along the Agano unrecognised and therefore ineligible for support or compensation. Those involved in the ongoing legal case were required to make an arduous journey to Niigata once a month by bus or car, a heavy imposition on a community which is often elderly and suffering physical disabilities caused by the illness. As one elderly woman talks of her arched hand which she cannot straighten, a man shows her his burned foot after treading on the heated rail for his bath and being unable to feel it because of the loss of sensation caused by the Minamata disease.
The fact that the river by which so many lived became actively harmful contributed to the rural exodus and decline of traditional ways of life along with skills which may then die out with no one to pass them on to. Boatmaker Endo had long since retired from making boats and had never taken on any apprentices but at an advanced age finally consented to teach a local carpenter how to make boats the traditional way, a special Shinto ceremony conducted as the next generation boat is completed. Meanwhile we also see a Shinto ceremony performed for the Mushi Jizo which protects people from disease born by insects such as the tsu-tsu living in the river which both gives and takes. Gently observational, Sato captures these disappearing ways of life with a poignant lyricality while equally addressing the politicisation of life along the river in a sense poisoned by modernity as the villagers must come together to fight for justice in a society which seems to have all but forgotten them.
