Company information
Nakashima Shokai Co., Ltd. is a specialized trading company for paints. We handle products from over 1,000 paint and coating-related manufacturers, primarily focusing on Nippon Paint. Among these, we boast a top-class handling volume in the field of general-purpose paints for residential and other general buildings, as well as for the interior and exterior of factories, anti-corrosion coatings for complexes and bridges, and we cater to all fields including automotive paints (as a subsidiary, NNC) and industrial paints. We operate nationwide in Japan, responding to various needs and continuously supporting our country's industrial sector, infrastructure development, and people's lives from the side. Paint is, in a sense, a semi-finished product. Its product value is only realized once the coating is completed. That is why at Nakashima Shokai, we do not simply move products from one side to the other; as professionals in paint and coating, we provide various proposals and technical services as added value, and sometimes we finish the coating together with our customers. We have received high praise for our ability to resolve any paint-related inquiries by contacting Nakashima Shokai.
