ISHIKAWA CO., LTD.

Ishikawa Co., Ltd. is a premier Japanese custom home builder with 80 years of experience in high-performance residential construction. Founded in 1947 and building over 1,000 homes annually, we have been the #1 builder for 15 consecutive years in our home region of Niigata—an area famous in Japan for extreme heavy snow, high humidity, and strict seismic demands. Homes built to survive and thrive here are engineered for world-class durability and comfort.

We are making our North American debut at IBS 2027 to introduce our innovative approach to Indoor Air Quality (IAQ) and energy efficiency. Our signature technology is the "Blow Box" System, a proprietary, patented whole-house air circulation and purification system. Using advanced photocatalytic (titanium dioxide) technology, it actively breaks down viruses, VOCs, mold, and odors, while maintaining perfectly uniform temperature and humidity in every corner of the home.

Unlike traditional luxury whole-house systems, our philosophy is to deliver high-performance, net-zero-ready living at an accessible price point. We are exhibiting at IBS to connect with forward-thinking US builders, HVAC professionals, distributors, and engineering partners. We are actively exploring joint ventures and licensing opportunities to integrate our battle-tested Japanese building science into the North American market.
