Mizkan and Kitasanriku Factory Launch Joint Research to Advance Land-Based Sea Urchin Aquaculture

Kitasanriku Factory Co., Ltd. and Mizkan Co., Ltd. have agreed to begin joint research on May 27, 2026, focusing on the development of feed optimized for farmed sea urchins. By integrating their respective management resources, technologies, and expertise, the two companies aim to advance demonstration experiments for land-based sea urchin aquaculture and contribute to 'connecting the health of the ocean and people, and the culture of sushi to the future.'

Background: While Japanese sushi culture is a global culinary treasure, the marine ecosystems that support it are in crisis due to climate change and 'isoyake' (barren rocky shores). Sea urchins are high-demand luxury ingredients, but they are also a direct cause of isoyake, raising sustainability concerns. Kitasanriku Factory has been working on environmental restoration through 'regenerative aquaculture,' while Mizkan has been exploring ways to contribute to sushi culture through its pursuit of 'deliciousness and health.' The companies will leverage Mizkan's food processing know-how and marketing power to promote the social implementation of land-based sea urchin farming.

The research will focus on three main areas: establishing the taste of farmed sea urchins, developing feed, and branding. Both companies are committed to building a sustainable model for primary industries and food culture, aiming to spread a rich sushi culture from Japan to the world.
