Ai Robotics Corporation, headquartered in Minato-ku, Tokyo, announced that its beauty appliance brand, Brighte, launched a new hair iron, the “3D SILK STRAIGHT IRON,” on January 6, 2026. On its debut day, the product secured the No. 1 position in the home appliance category on Rakuten, one of Japan’s largest e-commerce sites, and achieved a total of four crowns.
The four daily ranking crowns on Rakuten include:
-
No. 1 in Home Appliances
-
No. 1 in Beauty and Health Appliances
-
No. 1 in Hair Dryers and Hair Irons
-
No. 1 in Straight and Curl Dual-use Irons
The “3D SILK STRAIGHT IRON” is currently available for purchase on Rakuten, Brighte’s official website, and at electronics retailers nationwide.
Product Overview: “3D SILK STRAIGHT IRON”

The “3D SILK STRAIGHT IRON” marks a shift from conventional straight irons that merely straighten hair. This next-generation iron incorporates Brighte’s advanced beauty technology to deliver a “captivating nuance straight” style.
Brighte’s proprietary 3D Silk Panels ensure even heat distribution to the hair, minimizing damage while creating natural, lustrous hairstyles. The design features optimized heat and pressure control, resulting in voluminous roots and soft ends, leading to a three-dimensional finish akin to a professional salon styling.
Furthermore, the iron is designed to reduce hair color fading by approximately 58%, helping to maintain beautiful hair color for longer. Dual positive and negative ions work to suppress frizz and flyaways, providing a natural, cohesive, and moisturized finish from root to tip.
Based on internal measurements comparing with a non-functional product (without dual ions, without silk processing). Results obtained by setting the iron temperature to 140 degrees Celsius and passing heat through 40 times. Effects may vary depending on usage environment (temperature, humidity, etc.) and individual differences.
