About Kamiya Housei

Japanese Apparel OEM Manufacturer in Hamamatsu, Shizuoka | Over 50 Years of Sewing Expertise | From Individual and Small-Batch Orders to 10,000 Pieces per Month

Kamiya Sewing Co., Ltd. is an apparel sewing manufacturer headquartered in Hamamatsu, Shizuoka Prefecture, Japan. Founded in March 1970, the company began by making traditional yukata garments and has since accumulated more than 50 years of sewing and manufacturing experience. Its product range has expanded to include surf shorts and surfwear, women's clothing, trousers, skirts, dresses, blouses, shirts, jackets, coats, and knitwear. The company accommodates a wide range of customers, from individuals and emerging brands to established apparel businesses, offering flexible production from small batches to large orders.

One of Kamiya Sewing's key strengths is its integrated production system, covering fabric sourcing, pattern making, sample development, cutting, sewing, inspection, finishing, and delivery. Sample development and pattern making are carried out in-house, allowing the company to work from reference garments or basic design concepts even when existing patterns are unavailable. Its experienced staff discuss product requirements with clients and help determine suitable construction methods and specifications for original product development.

The company manufactures a broad range of apparel, including trousers, skirts, blouses, dresses, shirts, camisoles, cut-and-sew garments, T-shirts, jackets, coats, blousons, and jumpsuits. Its sewing capabilities also extend beyond conventional clothing to uniforms, festival garments, traditional Japanese workwear, aprons, children's clothing, pouches, tote bags, nylon backpacks, pen cases, curtains, baby products, maternity record book cases, baby bibs, seat covers, masks, and promotional goods. The company welcomes inquiries about products with specialized specifications or intended uses.

Its production facilities include CAD/CAM systems, fabric spreading machines, and fusing roller presses, along with a wide variety of industrial sewing machines. These include lockstitch, compound-feed, twin-needle stitching, zigzag, lap-seam, merrow, interlock, buttonhole, bartack, and button-sewing machines. Equipment is selected according to each product's materials, construction, and sewing requirements. The company has a production capacity of approximately 10,000 pieces per month, with dedicated production lines for trousers and skirts, blouses and dresses, and other products. It also has access to manufacturing arrangements in China for processing trade.

Kamiya Sewing can assist with fabric and trim sourcing and accepts customer-supplied materials. Taking advantage of Hamamatsu's textile industry network, the company can introduce local fabric suppliers and propose materials suited to specific products. This allows it to support product development from both the material selection and garment construction perspectives.

Additional processing services include garment washing, garment dyeing, embroidery, button attachment, pleating, screen printing, and sublimation printing. The company can discuss suitable finishing techniques during the development stage to achieve the desired appearance and functionality. Sample-only orders are also accepted, allowing clients to evaluate construction and finishing before proceeding to bulk production and request adjustments as needed.

The company accommodates small-batch production while adjusting production-line staffing to suit order volumes and improve manufacturing efficiency. By managing cutting, sewing, inspection, and finishing in-house, it reduces unnecessary delays between production stages and can support shorter lead times. Located in Hamamatsu between Tokyo and Osaka, the company is also well positioned to arrange deliveries to both the greater Tokyo area and the Kansai region. Finished goods can be delivered folded or on hangers, depending on the client's requirements.

With more than 50 years of sewing expertise and a flexible domestic production system, Kamiya Sewing is a Japanese manufacturing partner for individual creators, emerging labels, and established apparel brands seeking small-batch or bulk production. Its integrated services cover fabric sourcing, pattern making, sampling, sewing, secondary processing, inspection, and delivery, making it a suitable option for businesses seeking a Japanese sewing factory for original apparel and other sewn products.
