To protect customers from health risks posed by counterfeit products.

Tsuyoshi Matsushita

In recent years, as global e-commerce rapidly expands, the problem of counterfeit goods has spread worldwide through the Internet, with tactics becoming more sophisticated and malicious. Counterfeit products, exemplified by copies, not only lead to potential market loss and a decline in brand image but also pose the risk of health hazards due to inferior quality for customers.

We maintain a strong stance of "absolutely not tolerating counterfeits" to protect customers from the dangers of these malicious counterfeit products. To ensure customers can use our products with peace of mind, we will actively work to eradicate counterfeits on a global scale.
