Seaweed Cultivation for Ocean Restoration Initiative

A network organization connecting satoyama (marginal grassland/forest) conservation efforts across Japan. Integrating traditional wisdom from agriculture, forestry, and hunting with modern conservation ecology, it revives satoyama biodiversity. Through community and NGO collaboration, the initiative simultaneously restores abandoned farmland and protects endangered species.

Coastal regions like Tottori Prefecture implement ocean ecosystem restoration through seaweed cultivation. Kelp, wakame, and seagrass cultivation achieve carbon sequestration through blue carbon absorption while restoring marine biodiversity by addressing barren ground issues. Cultivated products' use in food, fertilizer, and bioenergy creates an established sustainable business model integrating fishing operations with environmental restoration.

A project cultivating coastal seaweeds (wakame, kombu, and hondawara) at scale to simultaneously achieve blue carbon sequestration and marine ecosystem restoration. Fishing cooperatives from Hokkaido to Kyushu participate, creating a new model balancing climate action with fishery revitalization.

Large-scale seaweed (kelp and wakame) farming restoring ocean ecosystems while absorbing CO2. Led by Hokkaido and Tohoku regions, gaining international recognition as blue carbon technology. Extracting fertilizer, biomass, and food ingredients from seaweed simultaneously enhances fishing income and restores marine ecosystems. Emerging as innovative model integrating climate change mitigation with regional economic regeneration and sustainable ocean resource management.

A marine restoration initiative in Seto Inland Sea fishing villages using seaweed farming. Large-scale cultivation of high-carbon-absorption seaweed simultaneously combats ocean acidification and restores fishery resources. Through partnerships between local fishers and venture companies, it exemplifies circular economy practices while creating sustainable livelihoods.

Tottori's coastal ecosystem restoration through strategic seaweed proliferation. Cultivating wakame and kombu prevents barren rocky coasts while simultaneously achieving carbon absorption and fishery resource recovery. It exemplifies advanced climate action through blue carbon utilization.

A large-scale kelp afforestation project addressing coastal seabed desertification in Tottori Prefecture. It restores marine ecosystems damaged by overharvesting of sea urchins through kelp cultivation, while achieving carbon sequestration and blue carbon effects. Implemented collaboratively with local fishers, it demonstrates sustainable marine resource management. A pioneering model integrating marine biodiversity restoration with climate action.
