He was born in 1969. After earning his doctoral degree at Kinki University, he joined the Fisheries Laboratory of Kinki University (currently Kindai University). Starting in 1997, he worked as a researcher, assistant professor, and associate professor, conducting research in the fields of aquaculture production science, fish nutrition, fish physiology, fish biochemistry, fisheries food chemistry, and aquaculture environment. His research focused on species such as red sea bream, yellowtail, amberjack, eel, and bluefin tuna. Simultaneously, for over 20 years, he gained field experience in almost all areas of aquaculture, including sea farming, land-based farming, larval production, broodstock management, harvest/shipping, processing, and vessel operation/maintenance, in an environment where "fish are next to the lab, and the lab is next to fish."

In 2010, he was appointed as a Research Professor at the Technical University of Cartagena (Universidad Politécnica de Cartagena) in Spain and led a research and development project on the seedling production of Atlantic bluefin tuna in collaboration with the Government of the Autonomous Community of the Region of Murcia, the Spanish Institute of Oceanography (IEO, Instituto Español de Oceanografía), and Ricardo Fuentes e Hijos, S.A. He also participated as a Special Collaborator in the EU project SELF-DOTT, which focused on domesticating this species. The project achieved a world-first in complete aquaculture of this species when the juveniles produced in these projects spawned in 2016.

From 2013, he worked at the Aquaculture Research Center of Skretting (Skretting ARC, now Skretting AI) and the Japanese subsidiary (Skretting Japan, Co., Ltd.) as a Senior Researcher and R&D/formulation manager. He was involved in research on the ingredients, formulation, and production of fish feed, contributing to developing sustainable and functional feeds. He also collaborated in technological development and improvement in production and breeding, responding to requests from aquaculture/larval production companies and institutions.

In August 2018, he established Seoka Aquaculture Consulting independently in Fukuoka, Japan. He is engaged in a business that provides scientific and practical consulting services based on his many years of experience with partners in Japan and abroad (aquaculture companies, raw materials/feed additives businesses, feed manufacturers, etc.) and cooperation in the academic field.
