When Mr. and Mrs. Saito founded Amurita Farm in 2014 on a forested mountainside in Niseko Town, Hokkaido, they were starting with land that had no agricultural history. Over the following decade, they converted that raw terrain into a certified organic operation with six greenhouses, award-winning produce, and a documented track record of biological resilience — using fermented microbial inoculants as a core tool throughout.
The farm takes its name from “Amrita,” the Sanskrit word for the divine drink of immortality, and is guided by a philosophy the Saitos call “Sanpo Yoshi” — good for all: the seller, the buyer, and society. That philosophy shaped how they approached the land: not as a substrate to be forced into production, but as a living system to be cultivated and supported.
Their use of fermented microbial inoculants — what EM Research Organization documents as EM Technology — permeates every level of the farm system. Water from a biotope reservoir on the property passes through a specialized filtration system incorporating EM Gravitron Charcoal and EM Ceramics before it is used for irrigation. Soil fertility comes from EM Bokashi and homemade fermented liquid fertilizer, applied without chemical pesticides, herbicides, or synthetic nutrients. In 2022, they installed EM Rectifying Barriers in the greenhouse structures — bottles and charcoal attached to the pillars and extended through the facility lines — creating what the farm describes as a more harmonized energy field between plants and the surrounding environment.
The results have been measurable. In the Japan Organic Farming Association’s “Healthy and Delicious Produce Contest,” Amurita Farm earned top prizes in both the spring-summer and autumn-winter categories — and repeated that achievement for the third consecutive year in 2024, from a program that began in 2021. Contest organizers described their accomplishment as “a record hard to beat” and the farm as “legendary in the making.” Their tomatoes demonstrated measurable increases in sugar content and antioxidant levels compared to conventional benchmarks.
The most striking documented outcome, however, came during a flooding event in 2023. When Hokkaido experienced record-breaking heat waves and severe flooding that season, the farm’s greenhouses were tested in an unintended side-by-side comparison: Greenhouse No. 3, which had no EM barriers installed, experienced water intrusion 23 meters into the structure. Greenhouse No. 4, which had EM barriers in place, limited water intrusion to 13 meters. “Thanks to the EM barrier, I experienced firsthand how a major disaster could be reduced to a smaller one,” said Mr. Saito.
What the Amurita Farm case illustrates — beyond any specific metric — is that a whole-farm biological approach compounds over time. The biotope, the treated water, the fermented fertilizer, the soil biology, and the plant health are not independent variables; they are a system that the Saitos built and maintain together. The results they document appear to reflect the accumulated benefit of a decade of consistent biology-first management, not any single input or intervention.
For growers considering a fermented microbial program, this case suggests that the ecosystem-level benefits — improved resilience, better nutrient cycling, healthier produce — may be proportional to the consistency and depth of the biological investment across the whole farm.
