せいさ工材 Company Profile

We handle a wide range of construction materials, focusing on plastering materials, and our staff is knowledgeable about the products, allowing us to meet the needs of various job sites.

Seisa Kōzai Co., Ltd. is a company established in 1948 with investments from members of the Shizuoka Prefecture plastering union. Its purpose was to supply plastering materials that were difficult to obtain in the post-war period to its members. Although circumstances have changed in recent years, our management stance remains unchanged in order to support the operations of the Shizuoka Prefecture plastering industry union and contribute to the prosperity of the industry, as well as to ensure the satisfaction of our customers and employees. At times, we have received strict guidance and encouragement from our shareholders and union members, and without forgetting the spirit of our founding, we have continued to make steady progress to this day. Moving forward, we are committed to the management philosophy of supplying "healthy and environmentally friendly plastering materials," including the discovery of new materials.
