Roki Techno

What Roki Techno does

Roki Techno Co., Ltd. is a Japanese private manufacturer founded in 1978 and headquartered in Tokyo (Higashi-shinagawa) with a regional presence in Toyama. The company specializes in industrial precision filtration and ozone-related technologies, producing high-precision industrial filters and ozone-related products that serve semiconductor and biopharmaceutical production processes. Roki Techno self-identifies as a leading supplier in Japan's domestic industrial precision filter industry and operates dedicated R&D centers alongside its production bases. Its core technical differentiator is proprietary know-how built up over 47 years in both filter and ozone domains, with quality framed across three perspectives — employees, work, and products.

The company operates a direct B2B sales model targeting industrial customers within Japan, with no disclosed international footprint. Its go-to-market combines an inbound website inquiry channel, a corporate blog and news platform (Roki Times), social media (X, Instagram, Facebook, YouTube), and targeted B2B events such as semiconductor and biopharmaceutical industry exhibitions. Pricing is not publicly disclosed. Marketing activity in 2026 expanded materially with the company's first corporate television CM and Yokohama DeNA BayStars stadium advertising, both signaling a deliberate brand-building effort.

Roki Techno has begun diversification through wholly-owned subsidiaries. In October 2025 it launched Roki Techno Farm, a completely closed plant factory producing pesticide-free agricultural products — a move that extends its controlled-environment process expertise into a new vertical. The company also operates Roki Techno Toyama, a corporate social baseball team. Its stated long-term objective is to exist as a '100-year company,' anchored on continuous transformation and relentless pursuit rather than near-term scale.
