Originally founded in 1947 as a construction materials manufacturer, Inoue Shoji now manufactures and sells aluminum drainpipes and other products.
We began manufacturing aluminum construction materials in 1977, and started manufacturing aluminum drainpipes in 2003. We are the pioneers of aluminum drainpipe manufacturing in Japan, and still hold the top market share today.
Annual sales in the aluminum construction materials sector in Japan represent 5 billion yen.
Our head office is located in Fukui prefecture, near the center of Japan, and we also have 12 branches and sales offices across the country.
We do more than simply sell products to our customers. It is our goal to provide the best new products and superior service through continuous innovation, streamlined management systems, and the flexibility to quickly adapt to evolving industry needs and expectations. We remain committed to product development and technical standards.
