- Origin -
KOSO was officially born out of the realization that an independently developed brand is indispensable for future market marketing. Therefore, KOSO was registered as a trademark of Tong Ya in 1989. KOSO is derived from the Japanese words "Concept" and "High Speed". Concept represents creativity, while High Speed represents high-performance expression—combined, it expresses the hope that the company can use creativity to create high-performance products!
- Spirit -
The brand spirit that KOSO pursues is to build quality, technology, and service on the foundation of integrity and mutual trust. We persistently hold this attitude, not only manufacturing high-quality products but also pursuing product innovation and quality improvement, hoping to bring more excellent products to everyone.
- Brand Journey -
Pursuing perfect product design and quality has always been our goal. Therefore, KOSO constantly spurs itself on by improving its own technology. We firmly believe that brand image and product quality are synonymous! Therefore, the company has strict requirements for product development, production processes, and quality control, hoping to achieve the goal of high quality while stepping onto the world stage. In the future, KOSO will continue to develop more user-friendly and innovative products, and hopes to become the next world number one from Taiwan within ten years, another pride of Taiwan, and the pride of Taiwanese people.

【Notes Before Ordering】
Before ordering, please double-check the color, size, and other information you wish to purchase.
Most products have delivery times provided after the order is placed, so there may be situations where products are discontinued or require a long wait for shipment.
If an order cannot be fulfilled due to manufacturer stock shortages or temporary unavailability, it will not be processed; no fees will be charged if the order is not processed.
Please be aware that manufacturers may unilaterally change specifications or exterior designs, which may result in the packaging or the product itself differing from the images on the product page.
If a manufacturer's unilateral change in product design or specifications prevents the product from performing its intended function as expected at the time of order, please consult our customer service for further assistance.
Products undergo multiple shipping processes from order to delivery, so packaging may be deformed or damaged during transit, even if the product itself remains intact and functional.
