About Dainan Co., Ltd.

Japanese Garment Manufacturer Offering Integrated Production from Pattern Making and Sewing to Embroidery, Printing, and Quality Inspection — From 5 Pieces to Large-Scale Production

Dainan Co., Ltd. is a Japanese garment manufacturer established in December 1972 and based in Oita City, Oita Prefecture. Guided by its philosophy, “Think with Our Hands, Move Hearts,” the company provides a comprehensive range of textile and garment manufacturing services, including product planning, design, pattern making, fabric cutting, sewing, embroidery, printing, finishing, quality inspection, and shipping. Its product capabilities span babywear, children's clothing, women's apparel, casualwear, sportswear, and a wide variety of sewn textile products.

One of Dainan's key strengths is its integrated production system, which enables the company to manage projects from initial planning through bulk production and delivery. Its planning and sample development team creates patterns and prototypes while considering the requirements of efficient bulk manufacturing. Dedicated departments coordinate cutting, sewing, finishing, inspection, storage, and shipping to maintain quality and meet delivery schedules. The factory is equipped with CAD/CAM cutting systems, automatic fabric spreading machines, embroidery machines, and needle detectors to support consistent quality and efficient production.

Dainan also provides secondary processing services, including embroidery and printing. These capabilities include embroidery data creation and screen printing, supported by in-house operations and collaboration with its group companies. The factory also has a dedicated workshop for developing custom equipment and sewing attachments. For specialized specifications and technically challenging designs, the team explores practical solutions through prototyping and process development rather than relying solely on existing manufacturing methods.

Materials handled include knit fabrics such as interlock, jersey, French terry, and double-knit fabrics, as well as woven materials ranging from gauze to denim and canvas weighing approximately 10 oz. Products include T-shirts, polo shirts, hoodies, pants, skirts, dresses, jackets, and coats, along with sewn textile goods such as bags, pouches, bedding covers, pet clothing, shoe uppers, aprons, and various types of protective covers.

Dainan accepts production orders starting at just five pieces and can accommodate bulk production of 5,000 pieces or more per season. Its flexible production system supports both emerging brands requiring small quantities and established businesses seeking a reliable long-term manufacturing partner. The company also assists with product development challenges, including designs or processing requirements that other factories may find difficult to handle, using sample development and technical evaluation to find workable solutions.

With integrated capabilities spanning product planning, production management, secondary processing, quality inspection, and delivery, Dainan serves as a Japanese manufacturing partner for apparel brands and businesses developing sewn products.
