What Okuno Chemical does

Okuno Chemical (奥野製薬工業株式会社) is a privately-held Japanese specialty chemical manufacturer founded in 1906, headquartered in Osaka, with a secondary operating base in the greater Osaka area. The company operates through four business divisions: Metal Finishing (surface treatment chemicals including electroless plating, electroplating, and aluminum anodizing processes), Advanced Materials (glass-based functional materials including glass frit, glass color inks, and silica-based insulating coatings for automotive and electronics), Life Solution (food additives such as preservatives, quality improvers, and antimicrobial coatings developed over 120+ years), and Machine Engineering (production equipment design and process optimization services).

The company's technological core centers on surface treatment chemistry for advanced electronics, with proprietary platforms including the TORYZA brand for power semiconductor surface treatment, the PLOPX glass substrate electroless copper plating process (winner of the 18th JPCA Award), Top Cluster AR granular copper plating for power device lead frames (20th JPCA Award), and low-temperature Cu-Cu hybrid bonding additives co-developed with Yokohama National University. Its Cu-Cu Hybrid Bonding technology enables ultra-fine circuit formation down to L/S=1/1μm. The company also holds 100% domestic market share for glass color in beverage bottle applications and supplies glass frit to resistor, capacitor, LED, and solar cell manufacturers.

Okuno Chemical generates revenue through direct enterprise sales of specialty chemicals, food additives, and production equipment to manufacturers across five primary verticals: electronics and semiconductor packaging (primary), automotive, food processing, consumer electronics, and industrial manufacturing. The company maintains wholly-owned subsidiaries in Taiwan (Taiwan Okuno) and Korea (Okuno Korea), with operations expanding into India, Vietnam, and Thailand, and participates in the JOINT3 27-company semiconductor packaging consortium. Following a leadership transition in June 2024 installing Naoki Okuno as President, the company has reorganized into a four-division structure (April 2026), launched the iCUBE next-generation factory (February 2024), and stated a target of 40 billion yen in revenue by FY2031 from a ~30 billion yen baseline.
