Kao Launches AROMAT® Deodorizing Rubber Mat Featuring “Harmocent Technology”
Godo Kaisha Uchino (Head office: Shibuya-ku, Tokyo; Representative: Tomoyuki Tamura) will launch "AROMAT®," a deodorizing rubber mat that incorporates Kao Corporation's "Harmocent Technology" into its original gym rubber mat "GYMMAT®." This product was developed with an innovative approach that converts the unique odor of rubber mats, which has been a long-standing concern in training spaces, into a pleasant fragrance.
Our original product "GYMMAT®" is a rubber mat widely used in home gyms and commercial gyms alike, and as of June 2026, it is a best-selling product with cumulative sales exceeding 400,000 units.
However, some users commented, "The rubber smell is stronger than expected" and "Even with ventilation, the rubber smell lingers in the room." The source of the odor is volatile components derived from vulcanization released from recycled rubber chips, and while various methods have been used to counteract the odor, a complete solution had not yet been achieved.
Therefore, with the cooperation of Kao Corporation, we developed "AROMAT®," a deodorizing rubber mat that incorporates "Harmocent Technology." "Harmocent Technology" is an innovative technology that incorporates malodorous components as part of a fragrance by adding a fragrance suitable for the cause of the odor, thereby converting unpleasant odors into pleasant fragrances. By adopting this technology, we succeeded in reducing the unpleasant odor of rubber mats to a level that is almost imperceptible.
Additionally, a new clean, fresh green scent was blended and adopted as the fragrance for "AROMAT®." By installing this product in a training space, a fresh and refreshing green scent subtly spreads. The scent of the mat is expected to last for a long period of over two years under normal use conditions (*1), and it also contributes to reducing maintenance costs compared to continuously scenting a space using air fresheners or aroma diffusers.
As of summer 2026, only tile-type rubber mats will be released, but from autumn 2026 onwards, we plan to expand all existing products, such as slopes, roll mats, and joint mats, into the AROMAT® series and release them.
*1 The long-term scent durability of the product is evaluated in a short period through an accelerated storage test at 60°C for 14 days. The actual duration may vary depending on the usage environment (temperature, ventilation conditions, sun exposure conditions, cleaning frequency, usage conditions, etc.), so this test result is a reference indicator for evaluating long-term stability.
