About EISEN Inc.

Jewelry and Accessories OEM/ODM Manufacturer Offering End-to-End Product Development | EISEN Co., Ltd.

EISEN Co., Ltd. is a Japanese OEM/ODM manufacturer based in Yamanashi Prefecture, specializing in the planning, design, development, and wholesale manufacturing of original jewelry and accessories. Since its founding in 1989, the company has supported product development and production for a wide range of clients, including department store jewelry brands, apparel brands, jewelry retailers, mail-order businesses, and concert merchandise companies.

One of EISEN's key strengths is its integrated production system, covering every stage from product planning and design to 3D modeling, prototype creation, sample development, mass production, repairs, and after-sales support. Its in-house designers and experienced staff work closely with clients to turn initial concepts into finished products. The company provides both OEM manufacturing based on client-supplied designs and ODM services that include original product planning and design proposals. It also supports new brand launches and product development aimed at expanding sales channels.

EISEN works with a broad range of materials, including platinum, gold, silver, brass, tin alloys, and acrylic. Based on each client's product concept, quality requirements, and target price, the company recommends suitable materials and processing methods. Its product range includes rings, necklaces, pierced and clip-on earrings, bracelets, brooches, keychains, and promotional merchandise. From premium precious-metal jewelry to cost-effective products manufactured through overseas partner factories, EISEN offers flexible production options to suit different market needs.

The company also specializes in distinctive processing techniques, including precision cutting and surface-finishing technologies, as well as shank wrapping, a delicate handcrafting technique in which metal wire is threaded through stones or other components to connect them. Its sourcing network provides access to Uwajima Akoya pearls, rare gemstones from Japan and overseas, and custom-cut stones and glass developed to complement specific designs. These capabilities enable EISEN to create distinctive products that make the most of each material's characteristics.

By leveraging its network of domestic and overseas partner factories, EISEN balances product quality, cost, and lead time to meet a variety of production requirements. From small-lot prototyping and product development to mass production, the company provides comprehensive OEM/ODM support for jewelry and accessories brands seeking a reliable manufacturing partner.
