Changing what farming
takes for granted — from Kawagoe.
We are expanding a farming cycle where producers and consumers meet — from Kawagoe to the world.
Vision
Our Vision
Connecting each person's potential to the future.
Everyone realizing their own aspirations, and spreading places that make “what you want to do” come true, all over the world.
Rooted in agriculture, we connect food, communities and people to create new value — from our region to the world.
Our vision is to keep increasing the places where challengers gather, learn, grow and realize their dreams.
Mission
Our Mission
01
Grow the potential of agriculture even further
Agriculture holds enormous potential that is still waiting to be unlocked. By combining technology with sound management, farming can become more profitable, more creative, and something to be truly proud of. We want children to light up and say, "I want to do that." That journey begins in our own rice paddies.
02
Build a system where producers can shine
Great taste begins with the hands and passion of the people who grow it. By standing in the field ourselves — growing, milling and delivering end to end — we create a flow where a grower's dedication reaches people as real value. Growers whose hard work truly bears fruit, and who keep going with a smile. We are nurturing that system from the ground up, and widening the circle of people cheering for Japanese agriculture.
03
Build an economy where producers and consumers meet
Every grain of rice carries its grower's story. By connecting production, technology, experience and distribution, we nurture an economy where growers and eaters know each other's faces. From Kawagoe to Japan, to Asia, to the world. We grow the harvest for everyone involved.
Areas of our work
Value
The values we cherish
01
Stand in the field
The answers are found on the soil. The morning water temperature, the color of the rice plants, the scent of the wind — we learn from facts confirmed with our own hands. That practice becomes words, and trust, that reach people.
02
Keep challenging
Meeting something new every day is the privilege of a founding team. Test fast, learn fast, and move on to the next step. We turn yesterday's lessons into today's strength — and enjoy every step forward.
03
Honor food & health
What we make goes onto someone's table every day. We deliver taste that people can enjoy with complete peace of mind. That sincerity is the foundation of everything we do.
04
Create together
Producers, customers, communities, colleagues — we are all crewmates on the same ship. We pool our wisdom and share the harvest. Together, we build ways of working that bring a smile to everyone involved.
05
Reach the world
Local value has the power to reach the world. We refine what we grow in Kawagoe's paddies and carry it across the sea. We will make the appeal of Japanese rice and farming a standard for the world.

Message from the CEO
Representative Director / CEO
Soichi Saito
SoA Co., Ltd. was founded on March 5, 2026.
Our challenge is to expand human potential, and the potential of Japan, through agriculture. As a first step, we started our farming business in Kawagoe.
Japanese agriculture holds great untapped potential. Yet at the same time, high walls stand in the way of new challenges. Securing farmland, investing in equipment, acquiring skills, building a stable management foundation — even with ambition, taking that first step is far from easy.
I see this not merely as a problem, but as a great opportunity. If we can create an environment where anyone can take on the challenge, agriculture can give more people dreams and hope, and become a force that supports Japan's future.
In my previous career at East Japan Railway Company, I was involved in work that supports communities and people's daily lives. What I learned is that the future of a region is created by those who take on challenges. New value is born from people who sweat in the field and keep moving forward despite hardship.
That is why I stand on the farmland myself and keep taking on challenges, getting muddy in the process. Starting from rice growing, I want to connect agriculture with food, distribution, technology and many other fields to create new value.
What we aim to be is not merely a company that produces crops. It is to create a place where challengers gather, potential grows, and a new future is born.
I believe that small challenges beginning in Kawagoe will, in time, move our region and move Japan.
When more people speak of their dreams, Japan can grow further.
SoA Co., Ltd. believes in that future and will keep taking on challenges.

Business
Starting from rice — connecting and circulating.
We run two businesses. Agriculture: growing rice in Kawagoe and expanding into experience and distribution. AI & digital: website and app development, built on what we practice in our own fields.
Our core today
Rice production
We grow rice on our own farmland in Kawagoe, Saitama. Adapting to climate change, we select varieties in the field to protect quality and yield.
- Now: Sai-no-Kizuna / Koshihikari
- From next year: considering Niji-no-Kirameki, Emi-hokoro
- Practicing the shift to heat-tolerant varieties
Supporting production
Use of technology
Using our own farmland as a proving ground, we test technologies for labor-saving and quality improvement in the field, accumulating cultivation know-how.
- On-site implementation of AI & IoT
- Both labor-saving and quality
- Systematizing accumulated know-how
Connecting value
Experience & distribution
Using food and experience as the entry point, we build distribution that connects producers and consumers directly — beyond Japan, with overseas exports (cross-border e-commerce) in view.
- Touchpoints through food & experience
- Distribution where producers sell at fair prices
- Overseas exports / cross-border EC in view
Business Model
A circular ecosystem starting from agriculture.
Production, processing, distribution, experience, consumption, reinvestment. SoA Co., Ltd. designs that cycle to create sustainable value for producers, communities and consumers alike.
Our Future
Toward the future, step by step.
As a newly founded company, we have a wide-open future to build. Here is a clear picture of where we are heading.
PHASE 1
Establishing production
Expanding rice production and building a sales base including direct sales and e-commerce.
PHASE 2
Creating places for food & experience
A place for food and a marché, then a stay-type experience facility, step by step.
PHASE 3
Toward a next-generation model
Systematizing the model honed in Kawagoe, looking to markets across Asia and the world.

Where We Work
Our base
Where we work is
Kawagoe, Saitama.
Located near the center of Saitama, Kawagoe is a historic castle town known as “Little Edo.” With good access from central Tokyo, this is where our activity begins.
Here we run our headquarters and own farm (3.8 ha of active farmland), growing Sai-no-Kizuna and Koshihikari — also serving as a proving ground for AI and IoT.
- Location
- Kawagoe, Saitama
- Farmland
- 3.8 ha

From Kawagoe, to Japan, and to the world.
