Business Overview
We are citrus growers based on the Sadamisaki Peninsula, the westernmost tip of Shikoku, Japan. Our mission is to practice regenerative agriculture that restores soil, sequesters carbon, and revitalizes rural communities. Agriculture is not only food production but a system that regenerates ecosystems, strengthens economies, and reconnects people with nature.
1. Citrus Farming without Chemicals
Our orchards are managed without pesticides or chemical fertilizers. Ground cover is returned to the soil to improve fertility and water retention, while insects and microorganisms are treated as ecosystem partners. This approach allows citrus to express unique flavors and terroir characteristics of Sadamisaki.

2. Biochar and Carbon Sequestration
Pruned branches and unused biomass are converted into biochar via pyrolysis. Unlike burning, this process locks carbon into a stable form and returns it to the soil. Biochar improves aeration, infiltration, and microbial activity, while serving as a long-term carbon sink. We also turn thinned timber and bamboo into biochar, linking agriculture with forestry and reducing waste.

3. Research Collaboration
With Ibaraki University we measure carbon sequestration, water infiltration, and microbial diversity after biochar application. Ehime University and others support soil and water studies. High schools and universities use our orchards as open laboratories. These projects provide data to validate regenerative practices and build trust with partners and consumers.

4. Product Development and Branding
We create processed citrus products that tell the story of regenerative farming: juices, teas, syrups, jams, and citrus powders. Each product communicates the value of “zero-carbon farming.” Purchasing means joining environmental regeneration. We are developing “Ne no Wa” certification to assign measurable soil and carbon value to products, adding a new layer of ethical branding.

5. Education and Learning Programs
Our orchards serve as learning sites. Programs range from one-day children’s workshops to high-school farmland restoration, university research, and corporate training. Participants experience biochar making, soil tests, and citrus harvesting, deepening understanding of natural cycles. These activities nurture the next generation and connect visitors with rural life.

6. Regional Circular Zone
Our goal is a Regional Circular and Symbiotic Zone where mountains, orchards, and the sea are linked:
・Forests provide biomass → biochar.
・Biochar enriches farmland → healthy crops.
・Landscapes feed clean water and nutrients → fisheries.

People engage through education, tourism, and culture.
This cycle regenerates nature, industry, and community, offering a model for depopulated rural areas.

Future Outlook
We will:
・Establish a carbon-negative model centered on biochar and citrus farming.
・Launch certification giving economic value to soil health and carbon storage.
・Expand ethical products to domestic and international markets.
・Combine education and eco-tourism to attract visitors and create regional vitality.

Through these efforts, we share the message that “eating mandarins can reduce CO₂.” From a small orchard on the Sadamisaki Peninsula, we are building a model that connects farming, research, business, and community to regenerate both people and the planet.
