Hamari Chemicals

What Hamari Chemicals does

Hamari Chemicals (浜理薬品工業株式会社) is a privately held Japanese pharmaceutical contract development and manufacturing organization (CDMO) founded in 1947 and headquartered in Osaka. The company manufactures active pharmaceutical ingredients (APIs) and intermediates across the full drug lifecycle — from drug discovery support and preclinical work through clinical trial supply to commercial production — for Japanese branded and generic pharmaceutical companies, international pharma firms, and peptide drug developers. Approximately 90% of revenue is generated domestically in Japan, with the balance from export sales.

Its core technology platform rests on proprietary chiral chemistry capabilities: the in-house HAMOC ruthenium-based asymmetric hydrogenation catalyst, the co-developed Soloshonok-Hamari chiral ligand for non-natural amino acid synthesis, and a patented humidification drying method that reduces residual solvent levels from over 3,000 ppm to below 200 ppm at up to 20 kg scale. The company also operates solid-phase and liquid-phase peptide synthesis (including high-potency peptide APIs at Category 4 containment), continuous flow chemistry developed since 2016, and supports high-potency API (HPAPI) manufacturing. Manufacturing is distributed across three Japanese sites — Osaka (HQ and research), Yonezawa (100t-scale GMP API production, FDA-inspected since 2006, fully renewable hydroelectric power since August 2025), and Chitose (GMP peptide and intermediate production, plus food extract processing).

Hamari operates a project-fee and contract-manufacturing revenue model, selling directly to enterprise pharmaceutical customers through dedicated sales departments (営業第一課, 営業第二課) and an international department, with a wholly-owned trading subsidiary in Shanghai and a US sales entity. The portfolio also extends to commercial generic APIs (Polaprezinc, Tamsulosin HCl, Edaravone, Ibuprofen), tailor-made non-natural amino acids sold as catalog products, and consumer health supplements (L-Carnosine, imidazole peptides) via subsidiary Hamari Pharmaceutical Nutritional Science. A holding company, HAMARI holdings, was established in October 2023 over the operating group.
