ABOUT US
About Us
A serious commitment to shrimp farming, born from an encounter with Thailand's vast shrimp ponds.
The industry is shifting from "catching fish" to "raising fish." Yet in Japan, land-based aquaculture has faced a high barrier in both cost and technology. We can offer a path to profitable land-based farming, proven in markets around the world — and we intend to be the pioneer that makes Japan's land-based aquaculture a sound and rewarding industry.
