Welcome to WKK Website

Best partner for road construction

Construction Network spreading out all over the world.

Since its establishment in 1970 the World Kaihatsu Kogyo Co., Ltd., WKK, has become one of Japan’s distinguished leaders in the field of asphalt paving and road construction technology.
Our commitment to quality work, reasonable prices, and our ability to do the job that other companies cannot, has helped us become the largest paving company in Nagano Prefecture.
WKK-owned machinery is controlled by our reliable management system with a stock of 460 construction machines, a highly skilled labor force and an effective management team; we are ready for any asphalt-paving job.
Roads, which we walk and drive everyday, are fundamental parts of our infrastructure. WKK has been always foreseeing what will be needed in the future and places special emphasis on “low impact road construction” and “dealing with environmental problem.”
We would always hope to suggest and practice new methods of using high technology to achieve our goals.
Every year, we carry out asphalt paving, concrete paving, surfacing dressing, maintenance and rehabilitation, milling overlay, crushing jobs, hard rock trenching, and joint sealing on expressways, highways and other roads throughout the Japanese archipelago.
