Global Trust, Uncompromising Quality, Independent Verification

At YAMAtune, our commitment to quality is unwavering, and its reliability is affirmed by rigorous independent testing conducted by KAKEN TEST CENTER, a leading international textile testing organisation in Japan. We are meticulous about every detail, ensuring our customers can embrace our products with complete peace of mind.

Unyielding Commitment to Safety:

In every YAMAtune product, we are dedicated to eliminating harmful chemical substances. Specific aromatic amines, known carcinogens, are "not detected (ND)" in any of our products, scientifically proving an extremely low health risk. Free formaldehyde, a potential skin irritant, is detected at exceptionally low levels of "20 ug/g or less," clearing the strict criteria of OEKO-TEX Standard 100 Class I. This globally recognised safety standard, equivalent to those for infant products in Japan, Europe, and the UK, ensures our products are safe even for children. These comprehensive test results unequivocally demonstrate that YAMAtune products present a minimal health risk from exposure to harmful chemical substances.

Uncompromising Quality and Durability:

Beyond safety, we make absolutely no compromises on product quality and durability. Every fabric undergoes rigorous inspection, guaranteeing that YAMAtune products consistently meet fundamental quality benchmarks. Our products also boast "high colour fastness" against washing, perspiration, rubbing, dry cleaning, and water. This means they are exceptionally resistant to fading and colour transfer during everyday use and repeated washing, ensuring their aesthetic appeal and quality are maintained for a long period. These rigorous test results clearly show that YAMAtune products are developed with maximum consideration for customer health and safety, whilst also being high-quality and exceptionally durable goods.
