Company information
Yamato Concrete Industry Co., Ltd. was founded in 1960 in Taba, Gushikawa Village (now Uruma City) by the founder, Kaneko Hokama. Overcoming numerous challenges, we have worked tirelessly as pioneers in the manufacturing of concrete products with the motto of "contributing to economic development and improving living environments." Today, in our business environment, we face strict conditions such as recent budget cuts in public works investments and a slowdown in the construction industry within the prefecture, leading to intensified competition for orders. In response to this, we have withdrawn from the Okinawa Prefecture Concrete Secondary Products Cooperative in December 2010 to improve customer satisfaction and are committed to delivering better products to our customers at lower prices.
