Our Mission

Creating a society that achieves both
stable food supply and chemical pesticide reduction.

We aim to simultaneously solve the challenges of increasing global food demand and the rising environmental and health risks caused by the repeated use of chemical pesticides, striving to realize safe, secure, and sustainable agriculture.

We challenge ourselves to spread environmentally friendly next-generation agricultural materials from Japan to the world, creating "a world where everyone can eat delicious food as much as they like."

Social Issues We Address

DEMAND 1.7x

Food Demand in 2050: 1.7x

Against the backdrop of global population growth and economic development, global food demand is predicted to increase from 3.43 billion tons in 2010 to 5.82 billion tons in 2050.
To maximize the production of high-quality crops, pesticides play a crucial role in protecting crops from pests and diseases.

RISK CUT 50%

50% Reduction in Chemical Pesticide Risk

While the need for pesticides grows with food demand, environmental burdens and drug-resistant bacteria caused by the continuous use of chemical pesticides are becoming serious issues.
Japan and the EU have set goals to reduce chemical pesticide risks by 50%, making the shift to "sustainable agriculture" that balances food security and environmental conservation an urgent task.

This conflicting challenge is solved by YSH Research Institute's
"Proprietary Underwater Plasma Technology."

TECHNOLOGY
TECHNOLOGY

Technology

Proprietary underwater plasma technology developed by the University of Hyogo.
Achieves over 100 times the treatment efficiency compared to conventional methods without bubbles.

FEATURE 01

PLASMA

Proprietary Underwater Plasma Technology

Our proprietary underwater plasma technology, originating from the University of Hyogo, is a novel method utilizing cavitation bubbles. It achieves over 100 times the treatment efficiency compared to conventional underwater plasma technology (without bubbles).
By applying high-voltage pulses 600,000 times per second within a water flow containing a massive amount of micro-bubbles of water vapor generated by cavitation, plasma is generated with high efficiency.

FEATURE 02

WATER

Proprietary Underwater Plasma Treated Water

Our proprietary underwater plasma treated water is 99.9% water, containing 0.1% hydrogen peroxide and trace amounts of electrode-derived nanoparticles.
We offer "Active Oxygen Type" and "Metal Ion Type" depending on the application. Research so far has demonstrated its potential to support a healthy cultivation environment for crops.
