I became a social entrepreneur because I am a father of children with disabilities.
When my first child was born with a disability, I felt the vulnerability of families like ours and realized how few truly safe and gentle care options existed. That pain became my driving force.
In 2012, together with researcher Kohei Nagatoshi, I launched the ORALPEACE Project with just ¥500,000 and a small team of parents who shared the same fears about their children’s future. We developed “Neonisin” — a revolutionary oral care technology derived from natural lactic acid bacteria that kills harmful oral bacteria yet is completely safe if swallowed. It was created for babies, the elderly, people with disabilities, and now even astronauts.
What started in a tiny rented room in Yokohama has grown into something far beyond what I imagined:
• Selected by JAXA and loaded onto the International Space Station (the world’s first oral care product in space)
• Winner of Japan Venture Awards Grand Prize & Minister of Economy, Trade and Industry Award
• Good Design Award recipient (including the first personal care product for space use)
• Now available in 15+ countries
After moving to California in 2022, we accelerated our global mission. In 2025, in response to the FDA’s announcement to phase out swallowable fluoride products for young children, we launched a new fluoride-free toothpaste gel for babies and kids using cutting-edge natural green technology. We are expanding from Japanese supermarkets in California to premium retailers like Whole Foods and preparing for local U.S. production.
My journey hasn’t been easy — I lost everything after the Lehman Shock, continued volunteer work by bicycle, and faced deep personal losses. Yet these hardships taught me that loneliness and setbacks are simply the price of individuality. With humility, belief, and the right companions, they can become our greatest strength.
ORALPEACE is more than a product. It is a movement to create jobs for people with disabilities, solve the “post-parental death problem,” protect children’s health and the planet, and contribute to humanity’s future — even in space.
If you share the vision of using business to build a kinder, healthier, and more inclusive world — whether you’re a parent, retailer, distributor, researcher, investor, or simply someone who cares — I would love to connect.
Let’s protect the smiles of the next generation, together.

Until the Edo period, the Nagatoshi area in the southern part of Kyushu was the Satsuma(Kagoshima) domain, and the remains and place names of the Nagatoshi castle by Mr. Nagatoshi who occupied this area from the end of the Kamakura period are still present. The grandfather’s dairy company was sold to a major urban capital by M&A to protect local employment, and the Nagatoshi clan left management. His younger brother moved to Hokkaido and runs a ranch with his family. He is father of two college students and one high school student.

“Thoughts every day; I want to convey the importance of the mouth to many people. I want to contribute to the creation of mouths that can be eaten deliciously. I want to support the health of many people’s mouths. I want to reduce people’s suffering and illness, and want to go surfing this weekend.
When I first met ORALPEACE, the thoughts I had been thinking about every day seemed to be tightly packed in the green package, and I fell in love at first sight. As a doctor, I would like to objectively evaluate ORALPEACE and study various possibilities of ORALPEACE. “
