Originally founded in 1947 as a supplier of building materials, Inoue Shoji is now a manufacturer and distributor of aluminum drainpipes and other products. We also supply concrete and petroleum products. We started making aluminum construction materials in 1977, followed by aluminum drainpipes in 2003. We pioneered the production of aluminum drainpipes in Japan, and still enjoy the largest section of the market today.
We do more than just sell products to clients. Our aim is to provide superlative new products and excellent service through ceaseless innovation, a streamlined management system and the flexibility to adapt quickly to the evolving needs and expectations of the industry. We remain committed to product development and improving technical standards.
Greetings from our president
" Never forget our manufacturing origins "
At Inoue Shoji, this idea is at the heart of all that we do.
Though we started out as a treading house, we are steadily becoming more involved in aluminum manufacturing as a manufacturer.
As a manufacturer, we are committed to supplying products that the market demands.
By supplying the finest quality products, we can create new markets, and this in turn allows us to create new forms of value as a corporation.
We believe that in order to make the finest quality products, we need innovation as well as the technical capacity to turn innovation into reality.
Also, training and developing our staffs’ faculties are the starting point for any and every form of creation.
If we take on new challenges, then we will have opportunities to discover our new forms of value.
The most important thing is to identify and create the necessity of ourselves. As a trading firm and as a manufacturer, we are creating the next future as a creator.
