The Okinawa Institute of Science and Technology (OIST) held the 2026 demo day for four teams selected for the eighth cohort of its startup support program, the OIST Innovation Accelerator.
Selected in 2025 as early-stage deep-tech startups aiming to address societal challenges through innovative technologies, each team received approximately ten months of support to help expand their businesses in or out of Okinawa. This included funding from Okinawa Prefectural Government and the COI-NEXT program (JST's "Program on Open Innovation Platforms for Industry-academia Co-creation"), as well as hands-on support from OIST Innovation.
At the 2026 demo day, the four teams presented their progress across sectors including healthcare, communications, aquaculture, and environmental technologies. They shared updates on technology development, proof-of-concept results, fundraising progress, and future market strategies, demonstrating how initiatives cultivated in Okinawa are beginning to expand both domestically and internationally.
CancerFree Biotech is developing personalized cancer treatments using organoids tailored to individual patients. It was able to secure an academia-industry partnership with Professor Franz Meitinger at OIST and saw its platform "EVA-Select" adopted by three publicly listed biotech companies, expanding the business model into B2B, and received five major awards in Japan. "Over the past year, we have achieved several milestones, including partnerships with companies in Taiwan, academic publications, and the initiation of clinical research," said CEO Po-Han Chen. In 2026, CancerFree plans to establish a Japanese subsidiary and laboratory, initiate clinical trial enrollment in both Japan and the United States.
Perseptive is building a resilient multi-network communication platform designed to maintain connectivity during large-scale disasters. Last year the company completed its Minimum Viable Product (MVP) and successfully conducted field tests together with OIST Accelerator alumnus startup Vyorius and the Japan Drone Organization (JDO). "We are also working to secure additional funding to accelerate our R&D efforts," said Kagendra Kumar Sengar, expressing enthusiasm for the next phase.
Strout focuses on digitizing aquaculture, leveraging on-site data to support more sustainable and efficient production. Through collaborations with aquaculture operators and activities in more than 10 countries, the company has built local and global partnerships with MoU signed with Kikino Tsuyu Distillery, Indonesian partners, and a JICA-supported feasibility study in Bhutan. Moreover, it closed a JPY 150 million seed round led by Yanmar Ventures in April 2026. "We aim to overcome language and cultural barriers and expand globally from Okinawa," said CEO Kaoru Hirabayashi.
Tlaloc Blue is developing AI-based upcycling technologies to convert organic waste into valuable resources. The company tested its first hardware prototype and conducted biological trials with a range of locally sourced organic waste streams including Awamori moromi, tofu okara, mozuku residues, sugarcane bagasse, and shikwasa samples, secured biowaste supply agreements and MoUs with tofu manufacturers and other food processors in Okinawa such as Kikunotsuyu and Kumesen, to explore the reuse of fermentation byproducts and develop circular models. "We plan to further focus on feed additives and applications in the aquaculture sector," said founder Karim Hoinen, outlining the next steps. In addition to MOUs with fellow OIST Accelerator startups Strout Inc., the company was also selected for the Keihanna Global Accelerator Program (KGAP+), awarded the Deep Tech Pioneer label at the 11th Hello Tomorrow Challenge, and was admitted to the Antler Residency program in Tokyo.
Launched in 2018, the OIST Innovation Accelerator was built on the vision of opening OIST's resources and scientific expertise to the world, while attracting diverse entrepreneurs and researchers to Okinawa. What began with support for a single team has grown into a program supporting four teams annually. With this cohort, a total of 19 teams have completed the program, reflecting the steady growth of the startup community centered around OIST.
"When the OIST Innovation Accelerator was first launched, we were not sure whether it would truly succeed in attracting not only researchers and engineers, but also entrepreneurial talent and innovators," said Lauren Hall, Vice President for Innovation at OIST. "However, your achievements have proven its value. This is just the beginning for all of you-take what you have learned here and carry it forward into your next stage."
Having completed the 10-month program, the four teams now move forward toward full-scale market entry. Innovations born from the fusion of science and entrepreneurship are beginning to spread from Okinawa to the world.
Building on this momentum, OIST is now looking ahead to the next cohort of innovators.
Applications for the 2027-2028 cohort are now open, with a deadline of June 28, 2026. Selected teams will receive up to JPY 10 million in non-dilutive project funding, approximately ten months of go-to-market and R&D support in Okinawa, and access to OIST's network of researchers and venture investors.
