The Japanese government is responding to national infrastructure needs by investing in the improvement and standardization of water and sewage systems across the country. By placing this initiative under national leadership, Japan aims to provide consistent, modern, safe, and effective water services on a regional scale. This move is aligned with the government's ongoing commitment towards ensuring public health, enhancing economic efficiency, and promoting sustainable development.

Infrastructure, particularly the water and sewage system, is a crucial societal element in densely populated Japan. The care and consistency concentrated on water supply and sewage treatment reflect Japan's emphasis on public health and urban functionality. With the modernization of these services through national oversight, citizens are expected to benefit from reliable water services, leading to a general increase in living standards and an improved quality of life.

Similar initiatives in the United States and EU are usually undertaken by individual states or cities, though there are overarching federal regulations and standards. The choice of Japan to centralize this effort in an attempt to ensure nationwide uniformity and quality is somewhat unique.
