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.

Japan Pit was featured on RKB Mainichi Broadcasting's "Aspiration, Passionate Companies."

  • COMPANY

Japanese Pit was featured on RKB Mainichi Broadcasting's economic program "Aspiration, Passionate Companies," which highlights companies with great ambitions active in various regions of Kyushu. ■ About the Broadcast Content Originally, Japanese Pit standardized and sold drainage covers (such as wiring pits and drainage pits) nationwide. Following the devastating flooding caused by the Mikasa River flood in Fukuoka City in 2003, the company began producing waterproof boards (flood control boards). In response to the increasing frequency of sudden heavy rains and the anticipated tsunami damage, our company continues to challenge itself to protect cities and lives from severe flooding. Our "passion for manufacturing" and vision for future disaster prevention and mitigation are condensed into a brief two-and-a-half-minute video. An archived video is available on the program's official YouTube channel, so please check it out using the link below. ▼ "Aspiration, Passionate Companies" Japanese Pit Broadcast Video Here https://youtu.be/_SIf9D8LJOk?si=g58Ep33GmJ2KT3bE
