日本ピット Company Profile

We offer a variety of living environment products, including wiring and piping, drainage pits, waterproof boards (water-stopping prevention equipment), and grating.

Nihon Pit was established in 1968 as Japan's first independent pit specialty manufacturer, standardizing and mass-producing traditional manhole covers. Since then, we have developed many products, including general wiring and drainage pits for construction, trench ducts and OA floors for office automation, and drainage troughs, among others. Moving forward, we will continue to pursue a wide variety of specialized pits (manhole covers) that transcend the boundaries of architecture, civil engineering, and facilities, always aiming to create products that are ahead of their time.

Business Activities

Flood prevention measures for tsunamis, storm surges, floods, and guerrilla rainstorms; HACCP support drainage systems, various types of grating; development, manufacturing, construction, sales, and maintenance of wiring pit hardware.
