  • SAKANA Dream — Japanese fish and its cuisine are a treasure of Japan, On the other hand, the variety of fish consumed on a daily basis accounts for less than 1% of all fish living in Japanese waters.

Aquaculture can provide a stable supply, however, it is not easy to keep fish in a small water cage and only a limited number of fish are delivered to the market. We, SAKANA Dream, select the most delicious fish from over 4,000 species in Japan, and make it possible to farm and produce them using the cutting edge technology. Our goal is to create the "world's most delicious fish" that no one has ever tasted before and deliver it to our customers.
