OHTA

What OHTA does

OHTA合同会社 (OHTA) is a privately held Japanese venture research company (godo kaisha / LLC equivalent) founded in 2018 and headquartered in Hakusan City, Ishikawa Prefecture, Japan, with an additional R&D site at the Ishikawa University Liaison Incubator (I-BIRD) in Nonoichi City. The company conducts pharmaceutical-science-based research and development on food and cosmetic raw materials, anchored by Research Director Prof. Tomihisa Ohta, a Kanazawa University Emeritus Professor who holds more than 40 patents. Its proprietary ultra-high-pressure nanomization (crushing) technology — combined with heat treatment, enzymatic processing, and fermentation — is used to improve the bioavailability and functionality of ingredients such as β-NMN, Coix (hatomugi) CRD extract, and liposomal Vitamin C. Products are hand-filled under Class 100 aseptic conditions, capping output at roughly 100 units per day.

OHTA operates three revenue lines: (1) direct-to-consumer sales of 'Pure Material Series' 100%-ingredient supplements via its ohtalab.shop e-commerce storefront (card payments via the Epsilon gateway plus convenience-store settlement); (2) B2B sales of nanomized food and cosmetic ingredients plus OEM contract manufacturing accepting small batches from 10 units upward; and (3) technology licensing of its nanomization process. Pricing ranges from ¥4,800 for a 30g liposomal Vitamin C SKU to ¥40,000 for a 15g NMN 100% powder. The only named B2B customer is Nahls Cosmetics, which uses Coix CRD Extract in whitening anti-aging products.

Following the January 2024 Noto Peninsula earthquake, founder Saigou Tomosumi (a former 30-year Fujitsu communications-systems engineer) pivoted OHTA into a fourth revenue stream — renewable energy — opening the 8 kW/h Hokuriku Vertical Solar Panel Demonstration Center in August 2024 in partnership with ALLUSIS and Suzuden, and signing a strategic partnership with Miratex Co., Ltd. (Gifu) in September 2024 for renewable-energy product development. The solar business leverages patented vertical-panel technology rated for 40 m/s wind speeds, 25-year durability, and end-of-life conversion to ceramic via special incineration. No funding rounds, parent company, or external institutional investors are disclosed.
