Meet the Startup: NoMy Japan

NoMy Japan K.K. is a subsidiary of Norwegian Mycelium AS, headquartered in Oslo, Norway. Following the development of fermentation technology in Oslo beginning in 2020, NoMy Japan K.K. was established in January 2024 to create a mycoprotein market in Japan.

NoMy transforms food industry side streams into sustainable, high-value ingredients. The company’s core approach involves cultivating filamentous fungi (mycelium) on liquid side streams—nutrient-rich by-products from food production that are often discarded. These fungi grow on the side streams and produce biomass containing approximately 50–60% protein, 20–30% fiber, and essential minerals. NoMy’s fungal fermentation technologies are proven, scalable, and cost-effective. The resulting mycoprotein has a mild taste and a meat-like texture, making it suitable for both food and feed applications.

NoMy’s largest partner is Nippon Beet Sugar Manufacturing Co., Ltd. (Nitten), Japan’s leading producer of beet sugar from domestically sourced raw materials. Nitten is a strategic investor and commercial partner listed on the Tokyo Stock Exchange and led a JPY 200 million investment in 2025. In the later seed round closed in May 2025, follow-on investments were made by TD Veen of Norway, EIT Food—an EU-backed innovation initiative—and Farvatn, in addition to Nitten.

Mycoprotein produced by NoMy offers multiple functional benefits as a healthy ingredient, with a Protein Digestibility Corrected Amino Acid Score (PDCAAS) of 0.96. Its most notable characteristics are its rich fibrous texture and high palatability, with no off-flavors. Several companies developing plant-based product lines, as well as meat and fish processing companies, have expressed interest in using NoMy’s mycoprotein to replace existing ingredients in pursuit of improved “deliciousness.”

Additionally, during the cultivation process, 80–90% of the nutrients in the water are removed, significantly reducing wastewater volume as well as the cost and energy required for treatment.

With tiny microbes, NoMy continues to create a significant global impact.
