Kita-Sanriku Factory Featured in WeAreAquaculture for SBIR-backed Sea Urchin Aquaculture Project

We are honored to share that Kita-Sanriku Factory has been featured in WeAreAquaculture, a California-based international aquaculture media outlet, for our pioneering work in land-based sea urchin aquaculture in Japan. This initiative is supported by Japan’s SBIR (Small Business Innovation Research) program, and aims to establish a sustainable model of sea urchin farming through habitat restoration and innovation.

The article highlights our collaborative efforts with local fisheries, our commitment to marine ecosystem revitalization, and our broader vision for expanding sustainable aquaculture practices.

Inaugural Australia UNI (Sea Urchin) Summit Strengthens Japan-Australia Partnerships for Marine Restoration and Industry Innovation

HOBART, TASMANIA – The inaugural Australia UNI (Sea Urchin) Summit, held at the Salamanca Inn and Mures Tasmania over 21 and 22 May, showcased the power of collaboration between Japan and Australia in tackling shared marine challenges and advancing sustainable industry innovation.

Jointly organized by Kita-Sanriku Factory Inc., General Incorporated Association moova, and the University of Tasmania, the summit welcomed around 60 participants—including scientists, seafood industry leaders, chefs, and policymakers from both countries. The program focused on restoring Tasmania’s kelp forests—damaged in part by overpopulated long-spined sea urchins—and unlocking the economic potential of Australian sea urchins for both domestic and international markets.

This landmark event was made possible through support from the Australia–Japan Foundation (Department of Foreign Affairs and Trade) and the Department of Natural Resources and Environment Tasmania, reflecting the shared commitment of both governments to environmental sustainability and economic resilience.

Yukinori Shitautsubo, Representative Director of Kita-Sanriku Factory Inc., highlighted the value of international cooperation:

“This summit symbolizes the strength of the Australia–Japan partnership in addressing environmental challenges and creating new economic opportunities. Together, we aim to restore marine ecosystems and build industries that benefit both nations.”

Key Highlights

  • Restoring Marine Ecosystems: Coordinated efforts to rehabilitate Tasmania’s iconic kelp forests, vital for biodiversity and carbon sequestration.
  • Economic Opportunities: Strategies to grow sustainable industries based on Tasmanian sea urchins, supported by bilateral expertise and market insights.
  • Cross-Cultural Collaboration: Strengthening ties between Japanese and Australian researchers, industry leaders, and communities through shared knowledge and joint initiatives.

Dr. John Keane, Wild Fisheries Program Leader at IMAS, emphasized the broader significance of the summit:

“This summit demonstrates how Japan and Australia can collaborate to address complex environmental issues while also fostering economic growth and cross-cultural relationships. It’s a testament to what can be achieved through partnership.”

The summit also paved the way for pilot projects focused on kelp forest restoration and sea urchin management, integrating scientific knowledge and industry innovation from both countries.

Mikiko Makka, Managing Director of moova, added:

“By bringing together leaders from Japan and Australia, we are advancing not just marine sustainability but also meaningful, long-term relationships. These partnerships are essential to achieving shared goals and mutual prosperity.”

Kita-Sanriku Factory and Yanmar Launch Pilot Project for Land-Based Sea Urchin Aquaculture

Yanmar Holdings Co., Ltd., and Kita-Sanriku Factory Co., Ltd. launched a full-scale pilot project on April 1, 2025, to develop a land-based sea urchin aquaculture system aimed at addressing “Isoyake”, or coastal ocean desertification.

The project is part of the Japan’s Small Business Innovation and Research (SBIR) program, which was selected by the Ministry of Agriculture, Forestry and Fisheries in October 2024. The project, with a total budget of 920 million yen, will focus on scalable, short-term aquaculture technology for deployment both in Japan and overseas.

The two companies will construct a large-scale land-based aquaculture facility in Hirono, Iwate Prefecture, with completion scheduled for autumn 2025. The facility will showcase UNI-VERSE systems®, an aquaculture solution designed to accelerate sea urchin growth and improve quality. The goal is to demonstrate efficient breeding systems capable of producing high-quality sea urchins for both local markets and export.

Tackling Isoyake with Regenerative Aquaculture

Isoyake, or coastal ocean desertification, a growing environmental issue characterized by the loss of seaweed beds along Japan’s coastal areas. In response to the threat of ocean desertification, which is partially attributed to overgrazing of seaweed by marine organisms such as sea urchins, Kita-Sanriku Factory has started an initiative called “Sea Urchin Regeneration and Cultivation”. This project aims to transform undernourished sea urchins – previously discarded as having no commercial value – into premium seafood products. By feeding the sea urchins for a short period of time, the company was able to greatly improve the size, color, and quality, and succeeded in realizing a taste comparable to that of the natural product. This advancement also enables year-round shipping, including the winter months when sea urchin are typically not available. It is also expected that the land-based aquaculture system will allow seaweed beds to recover, alleviating the problem of Isoyake.

This system was developed over more than seven years in collaboration with Associate Professor Ura and his team at Hokkaido University. The sea urchin feed “Hagukumutane®” and the structure of the fish tank and water tank are patented technologies of the Kita-Sanriku Factory.

Improvement in Actual Production through Sea Urchin Regenerative Cultivation

■ Yanmar Holdings’ Aquaculture-Related Technologies for Sustainable Fisheries

The Yanmar Group brings extensive expertise in land-based aquaculture systems, including fish tanks, automated tank washers, and shellfish seed technologies. The company’s advanced fluid analysis and automatic cleaning technologies will help optimize environmental controls in the new aquaculture system. Together with Kita-Sanriku Factory, Yanmar aims to refine the UNI-VERSE systems® technology to enable the efficient and sustainable production of high-quality sea urchins for export.

■Global Reach and Export Plans

While international demand for Japanese sea urchins is increasing, securing a high-quality supply has become more difficult due to a rise in the number of “skinny” sea urchins with extremely small gonads, the edible part of sea urchins. The regenerative aquaculture model developed by Kita-Sanriku Factory, in collaboration with the Graduate School of Fisheries Science of Hokkaido University and other research institutions, aims to address this supply gap and promote sustainable practices worldwide.

Kita-Sanriku Factory plans to export UNI-VERSE systems® sea urchins to the EU, the U.S., Dubai, Thailand, and other countries around the world. In 2025, the company will exhibit at four major seafood fairs in the world in Barcelona, Boston, Dubai, and Bangkok, establishing a global commercial distribution network.
