Since its establishment in 1947, Komei Seisakusho has been producing water supply equipment such as fittings and stopcocks used to supply water from water pipes laid in roads to individual homes. The usage conditions for water supply equipment vary depending on the region, such as whether it is cold or warm, and whether it is a plain or mountainous area. Therefore, the equipment used differs from one municipality to another. In other words, the ability to manufacture on a made-to-order basis is crucial. Naturally, it is essential to be able to handle high-mix, low-volume production, but the company has built an integrated system from design to casting, machining, assembly, and inspection, enabling them to provide water supply equipment tailored to each region. As a result, they have obtained administrative permits in over 520 regions throughout Japan.

In response to growing environmental awareness, one of the company's distinguishing features is its "Reuse System," an environmentally friendly recycling system. When replacing water pipes without shutting off the water supply, temporary pipes are used during construction. With conventional methods, these temporary pipes were discarded after the replacement. The company's Reuse System allows these pipes to be reused multiple times. "Temporary pipes are also a valuable resource. We thought about how we could reuse them," says President Tokiyoshi Kanemura. This system involves taking used temporary pipes back to the factory, cleaning, sterilizing, and inspecting them for reuse. By making temporary pipes usable only when and for the required period, the company has solved the waste problem and reduced costs. Furthermore, temporary pipes that have reached the end of their lifespan are crushed and pelletized, and reborn as marker stakes and buried marker sheets.
This reuse system has steadily gained recognition, receiving the "NBK Grand Prize" from the Kansai Business Council in 2004, the "Osaka Frontier Award" in 2005, and the "JNB Grand Prize - Excellence Award" from the Japan New Business Council in 2006, and being adopted in the Kanto region, including Tokyo, Chiba, and Saitama.

The company has already earned a high reputation in various fields, but it spares no effort in maintaining its high quality. It attaches QR codes to all products and thoroughly manages product inventory, while also possessing plasma emission spectrometers, emission spectrometers, and precision universal testing machines, and making full use of inspection equipment to ensure thorough quality control.
Recently, as part of expanding its business areas, the company has begun working on disaster prevention projects. To prepare for emergencies such as earthquakes, it has already installed emergency water taps that connect to emergency water tanks in parks and other locations, supporting local residents by providing access to drinking water.
"What is needed changes with the times. Therefore, it is important to adapt to these changes. Our company has expanded its business from water supply to disaster prevention, but our core focus will remain on water. This determination to be second to none in this field is the origin of Osaka's manufacturing. Our company aims to be a 'small giant,' a one-of-a-kind company in the water field," the president said with conviction.
