Founder / Sea urchin fisherman / Seaweed bed restorer (CEO, Kesamaru Marine LLC)

“For every bit of care we give,the sea gives back in kind.」

Twenty-five years ago, alarmed by a sea turning white with isoyake, he began restoring the seaweed beds alone. He has since brought a forest-like bed back to 2.5 km of the Kushiura coast.

Building the system, alongside the field.

Satoshi InadaSATOSHI INADA

Director

Born in Saga in 1986. After high school he studied at university in Shanghai. Returning to Japan, he worked in store and brand management and nationwide retail expansion at a Nordic apparel company in Tokyo. Exposure to Nordic sustainability thinking and its forward-looking action drew his attention back to his home prefecture, and in 2015 he returned to Saga, working in branding, project direction, and management centered on food and primary industry. Meeting the founder in 2020, he was struck by a conviction unlike any other and has walked beside the work since — co-founding BLUE REVIVE with him in 2026.
