What Howa does

Howa Co., Ltd. (株式会社HOWA) is a privately held Japanese automotive parts manufacturer founded in 1955 (formerly HOWA TEXTILE INDUSTRY CO., LTD., renamed in April 2019) and headquartered in Kasugai, Aichi Prefecture. The company designs, manufactures, and sells automotive interior and exterior components — including headliners (Japan's first, launched 1970), door trims, sunshade trims, trunk/luggage trims, tonneau covers, and a portfolio of Noise and Vibration (NV) products such as dash insulators, engine under covers, wheel house covers, and hood insulators. Its technology base rests on in-house urethane manufacturing, proprietary acoustic simulation tools (notably the Kato Model for porous-material acoustic propagation and Hybrid SEA analysis), award-winning products such as the X-band dash insulator (2015 Toyota Technology Development Award), and the 5Rs circular production framework that converts manufacturing waste (including ~150,000 tons/year of Japanese garment industry cutting waste) into automotive-grade components.

Howa operates a B2B direct-sales model targeting automotive OEMs and tier-1 suppliers (Toyota, Honda, Nissan, Suzuki, Daihatsu, Isuzu, Mitsubishi, Hino, Toyota Boshoku, AISIN, Hayashi Telempu, Webasto, and others) under multi-year platform-based supply contracts with bespoke project pricing and just-in-time delivery to OEM assembly plants. The company has no intermediary distribution layer; instead it runs its own sales departments by region and function. As of FY2025 (ended March 2025), Howa reported ¥1,041 billion in consolidated group revenue, 3,295 group employees, and registered capital of ¥302.4 million. Its geographic footprint spans Japan (5 plants plus 4 domestic subsidiaries), the United States (4 plants via American Howa Kentucky), Mexico, Canada, China (5 entities), Thailand, Indonesia, and Europe through Howa Tramico SAS (acquired in 2012 from TRAMICO SAS), with additional plants in France, Spain, Slovakia, and Portugal, plus a 2012 Faurecia joint venture (Faurecia Howa Interiors) and a partnership licensing the Kato Model into Japan Acoustic Engineering's STRATI-ARTZ CAE software.

Products and services

• Headliner (ヘッドライニング) Automotive ceiling lining made with proprietary urethane foam reinforced with glass fiber, offering lightweight construction, sound absorption, heat resistance, moisture resistance, and high dimensional stability. Supplied to automotive OEMs as an interior roof component.
• Sunshade Trim (サンシェードトリム) Trim component for sunroofs that blocks external noise and filters harsh sunlight and UV rays through its urethane layer while allowing pleasant natural light and ventilation into the vehicle cabin.
• Door Trim (ドアトリム) Interior door lining panels that serve as vibration dampers and sound insulators to reduce external noise and vibration intrusion into the vehicle cabin.
• Trunk/Luggage Trim (トランク・ラゲッジトリム) Interior trim components for trunk compartments including deck side trim and package trays. Functions as dampers, sound absorbers, and insulators while providing cushioning against impact and vibration.
• Tonneau Cover (トノカバー) Cover for cargo areas in passenger vehicles such as station wagons, SUVs, and hatchbacks. Can be detached or rolled up when not in use, made from cloth, vinyl, leather, or plastic.
• Dash Insulator (ダッシュインシュレーター) Sound insulation material fitted to the vehicle interior side of the dashboard. Reduces engine noise and road noise. Materials include recycled fibers, sound barriers, urethane foam, and films.
• Engine Under Cover (エンジンアンダーカバー) Sound insulation material mounted under the engine compartment. Reduces exterior vehicle noise and improves fuel efficiency through enhanced aerodynamic performance. Materials include PP/PE resin, PET, and GF fibers.
• Wheel House Cover (ホイールハウス) Sound insulation material installed in wheel houses. Reduces tire noise during driving and protects bodywork from mud and stone chips. Made from PET fibers.
• Hood Insulator (ボンネットインシュレーター) Sound insulation material fitted to the engine compartment side of the hood. Reduces exterior noise transmission. Made from urethane foam molded products.
• X-band Dash Insulator Proprietary dash insulator combining a perforated sound-insulation layer and film layer with reverse-phase vibration. Achieves reduction of mid-frequency engine noise while also enabling weight reduction.
• Zabtone Sound-Absorbing Material Ultra-fine fiber sound-absorbing material offering high sound-absorption performance and excellent thermal insulation properties.
• Feltop Mat (フェルトップマット) Recycled floor pad material produced from cutting waste and offcuts from apparel manufacturing. Made by cutting materials, adding modifying agents and adhesives, and pressing into sheet form. Used in dash silencers.

Quantifiable outcome

• X-band dash insulator reduces mid-frequency engine noise while achieving weight reduction — received 2015 Toyota Technology Development Award and CE Special Award
