Sunrock Company Limited (Japan)

Sunrock Company Limited (サンロック工業株式会社) is a Japanese wallpaper manufacturer headquartered in Osaka. The company traces its origins to 1930, when the founder's predecessor began producing small decorative papers (komagami, thin paper used to line boxes) and colored paper, from which the business expanded into printing. It was incorporated in 1952 and has since accumulated roughly nine decades of history in the paper and wallcovering trade. Sunrock positions itself as a "wallpaper manufacturing concierge," combining a wide range of techniques to realize imagery and design concepts. Its core offering is design-oriented wallpaper intended to bring richness and inspiration to daily living through beautiful patterns and color schemes. The company emphasizes craftsmanship and the long-cultivated skills of its artisans, allowing it to respond quickly to diverse wallpaper needs. Beyond conventional wallcoverings, Sunrock operates inkjet printing technology capable of printing on a variety of substrates. Because output is data-driven, the company can handle small production lots and accommodate photographs and illustrations, and it can adjust pattern scale to fit specific wall dimensions. This flexibility supports custom and short-run wall decoration projects alongside its standard wallpaper lines. The company remains a private, family-rooted Japanese manufacturer. Its official website presents its product philosophy, inkjet capabilities, and company profile, and it invites inquiries through a contact channel. As of the available evidence, Sunrock is active and continues to operate in the Japanese wallcovering market.

Sunrock Company Limited's history begins in 1930 (Showa 5), when the founder's predecessor started producing komagami — thin decorative paper used to line boxes — and colored paper. This paper business evolved into printing operations, laying the foundation for the company's later wallcovering work. In 1952 (Showa 27), the business was incorporated as a legal entity. From that point the company continued to develop its printing and paper-processing capabilities, gradually focusing on wallpaper and wallcoverings. Over roughly nine decades, Sunrock accumulated expertise in design, color, and substrate handling. In the modern era, Sunrock has adopted inkjet printing technology that allows printing on a variety of substrates. Because the process is data-driven, it supports small-lot production and enables the company to work from photographs and illustrations, adjusting pattern sizes to match wall dimensions. This capability complements its traditional design-oriented wallpaper lines. Today Sunrock presents itself as a "wallpaper manufacturing concierge," combining diverse techniques and flexible lot sizes to expand the possibilities of wallpaper for its customers. The company remains based in Osaka and active in the Japanese market.
