About us
President's Message
We were founded in 1901 in front of Tokyo Station by Tetsugoro Yabuhara as "Yabuhara Shoten (Yabuhara Store)". The location being one of the factors, a construction material store has been established to become what we are today.
Since foundation, we have been subsisted by two principles of the management i.e. "Solidity" and "Fortitude". They were derived from the spirit of our founder's motto -- "Luck, Steadfastness, and Patience". These credos have been kept over generations and keep breathing amongst us today.
Our company originates its business in the traditional wall plastering cultivated from time immemorial, the old world of Japanese custom in wood and mud walling. We have been able to conduct our business over 110 years. Our sincere appreciation goes to the customers and suppliers who have consistently stayed supportive of us all these years.
We wish for your unremitting prosperity and look for your continual relation with us.
