What Hardlass Holdings does
Hardlass Holdings Co., Ltd. (ハドラスホールディングス株式会社) is a Tokyo-based nanotechnology research and development venture founded in 2000, specializing in polysilazane-based high-function glass coatings for industrial and consumer surfaces. The company's core technology anchors active ingredients — silver and copper ions, conductive nanoparticles, fluorine-free polymer brushes — into a nano-level glass film, producing coatings with antiviral/antimicrobial, superhydrophilic, antistatic, oleophobic, and aerodynamic drag-reduction properties. The technology is commercialized through five technology platforms (sub-brands): Eco-HardoLass (superhydrophilic/self-cleaning), Bio-HardoLass (antiviral/antimicrobial/antifungal/odor-control), Touch-HardoLass (fingerprint/oil resistance), Aero-HardoLass (aerospace/electromagnetic), and Opt-HardoLass (optical/electrical), supported by application-specific products including HardoLass TrainGuard (railway) and HardoLass ProHydo (superhydrophilic exterior).
The company generates revenue through four streams: branded glass coating product sales (Dr.ハドラスEX, Dr.ハドラス プレミアム, HardoLass TrainGuard, HardoLass ProHydo), professional coating application services via the 除菌・バスター franchise and dealer network, technology licensing (notably to Toyota Home for embedded use as ホームコーティング on new detached houses), and channel distribution through over 1,500 golf specialty shops in Japan. Customer footprint spans railway (RENFE/Spain), residential construction (Toyota Home), automotive (Toyota Rental Lease Aichi), healthcare (dental clinics, BIANCA beauty clinics), consumer electronics (NEC PCs, Seven Bank ATMs), vending (Hokkaido Coca-Cola), aviation (Toki Aviation Capital partnership), retail (Maruzen Marunouchi), and sporting goods. The firm employs 101-250 staff across headquarters in central Tokyo and a manufacturing/engineering facility at the Matsuhidai Satellite Office in Chiba Prefecture (opened January 2021).
The firm is venture-backed, completing a Series B round of 2.5 billion yen in June 2026. R&D credibility rests on SIAA certification (positioned as Japan's only SIAA-registered antiviral glass coating), the Tokyo Metropolitan Industrial Technology Research Center's INNOVATION PARTNERSHIP AWARD 2022, ILS TOP100 STARTUPS recognition (2024), registered Patent No. 6764116 (golf club coating technology, registered September 2020), and a joint research course with Shibaura Institute of Technology established in April 2025. The company is led by Representative Director Yamamoto Hideaki with technical advisors including Professor Emeritus Oishi from Shibaura Institute of Technology and Takahashi Mitsuo as reform-group technical advisor.
