Tourists and expat residents alike are always surprised to discover artistically designed manhole covers of all kinds as they walk urban streets and even villages lanes. These are a rare sight outside Japan where, in spite of their weight, they would probably be stolen.

Where Did Artistic Manhole Covers Come From?

Sewer networks had long existed in Japan until foreign engineers introduced a modernized system in the 19th century. This system consisted of underground sewers with above ground access points called manholes. Manhole covers were given their name because, manholes had to be covered for obvious reasons.

Their initial geometric designs were not that remarkable. However, there was a momentous change in the 1980’s when the Japanese Government planned for new sewer systems. All communities would be equipped with new sewer systems that discarded above ground fire hydrants to enlarge streets and facilitate movement and access. However, this idea was met with heated resistance from some.

Implementing the New Sewer System Plan

broke down some initial resistance to the government’s plan. They hoped that these would promote the cities in charge of the covers’ maintenance. Manholes belonging to private electrical supply companies existed before this change. After the change, new manhole covers for sewers, water and fire hydrants suddenly dotted the pavements and streets of Japan.

Eventually, they even became great examples of urban art. Not only that, perhaps most astonishing was that these design efforts were officially organized by municipalities who devised the designs themselves. The first designs appeared in Nagoya City, later to be followed in the whole country.

The municipalities sent their designs to foundries who cast the designs into wrought iron. The designs used both neutral and bright colors to fill the designs thanks to highly resistant compounds. The results are often striking, although errors are still made. Take for example a recent mishap with a beautiful design of Shizuoka City’s bird emblem, the kingfisher, for a new fire hydrant manhole cover. The design had to be scrapped when officials realized it would become dangerously slippery in the rain, despite its impressive colors.

The Final Cover Design in My Collection

Now, I’ll conclude with a manhole cover designed with Lord Tokugawa Ieyasu in mind.

Sumpu was renamed “Shizuoka” during the Meiji period.

Lord Ieyasu spend his youth and much of his life in the Sumpu area, climbing the ranks to become a daimyo (local lord) before eventually rising to the seat of shogun (military ruler of the country). He retired to Sumpu, present-day Shizuoka, in 1607, making this city a fitting location for this manhole cover design.
