In Japan, modern sewer systems began to appear during the late 19th century, though evidence of older sewage systems dates back to over 2,000 years ago. Foreign engineers introduced the Japanese to modern, underground sewer systems with above ground access points called manhoru (manholes). At first, Japanese manhole covers used geometric designs similar to those used in other countries. In the 1980s, when communities outside of Japan's major cities were slated to receive new sewer systems, the public works projects were met with resistance – until one dedicated bureaucrat solved the problem by devising a way to make these mostly invisible systems aesthetically appreciated aboveground: customized manhole covers.
