We strive to empower people and communities with seaweed

We isolate seeds from seaweed that grows along the shoreline across
Japan and operate cyclic land-based aquaculture using underground
seawater, minimizing negative impact on the environment.

Our mission is to empower people and communities through cultivation
and consumption of high quality seaweed while working with local communities.

Technology to isolate seeds
from seaweed from all over the world

Pure and mineral-rich underground
seawater is perfect for seaweed and earth

Stable water temperature and optimal sunlight
absorption accelerate growth throughout the year

Ensuring the highest quality seaweed
that is extremely aromatic and with vibrant color

Underground seawater × Land-based aquaculture
Circular aquaculture system to empower people and communities

Underground seawater refers to natural ocean water that
permeates through the ground from the ocean and eventually springs out.
Naturally filtered, extremely clean and transparent underground seawater
promises stable water temperature year round, which promotes growth of
seaweed throughout the year that is rich in color and flavor.
Our workplace model emphasizes demographic diversity that
ensures employees engagement and motivation.

About Us

We began our research on compound aquafarming of seaweed and
abalone utilizing Deep Sea Water(sea water drawn from the depths of the ocean)
in 2009 at Muroto, Kochi, which was later commercialized.

April 2016 was a landmark year for us as we became the pioneer in
establishing a cutting-edge method of land-based seaweed aquaculture using
underground seawater, which led to the launching of Sea Vegetable Company LLC
where our goal lies to empower people and communities with seaweed business.
