Our Projects


MSO is engaged in various projects aimed to restore healthy seaweed forests across Japan.

Seaweed forests restoration

We work with local fishers, diving shops and volunteer divers to do various field activities to protect seaweed forests. Our activities include culling overgrazing urchins and installing spore bags (mature seaweed releasing spore to encourage wider spread of seaweed in the coming season).

Monitoring research

One of MSO's core strengths comes from the scientific background of Doctor Komatsu, our Representative Director, who has studied seaweed forests over decades with his expertise in remote sensing. Under his supervision, we have conducted monitoring research of seaweed forests in multiple areas across Japan - researching growing conditions of seaweed in the regions and impacts of urchins and herbivorous fish. We strongly believe scientific guidance is essential when tackling such a large-scale, long-term environmental issue.

Sharing knowledge

In Japan, there is little public awareness about seaweed forests and the current situation, not only among the wider public but also among divers. MSO organises various events including study groups, workshops and webinars to share knowledge about seaweed forests. We occasionally collaborate with other organisations to host events.
