Since its foundation in 1953, Shoseki Kako Co., Ltd. has been involved, as a group company of Showa Shell Sekiyu K. K., in the manufacturing and marketing of architectural and civil engineering waterproofing materials and asphalt mixture materials for road pavements.

Thanks to everyone's support and patronage, our company marked its 65th anniversary in March 2018.
We would like to express our sincere gratitude for the warm support of customers and various related parties who have been doing business with us for many years.
In order to continue responding to rapidly changing business environments, we decided to concentrate our business resources on the waterproof business by separating from the asphalt mixture material business in April 2018.
In the business area of waterproofing materials, we will encourage activities to further enhance the trust we have established with customers as Shoseki Kako of Polymer Modified Asphalt or “TOUGHNESS” in the 65 years of our history, and focus on the development of products adapted for the needs of our customers which are changing with the environmental changes.

We will also focus on new overseas business to further expand our activities to serve customers who are developing overseas operations, while offering excellent waterproofing quality in overseas markets as well by utilizing the waterproof products and waterproofing technology which have gained the trust of our customers in Japan.

We will continue to strive each day to respond to customer expectations with our trusted and reliable waterproofing technology.
I would like to take this opportunity to express our gratitude to all of our customers for their continued support and patronage.
