Nagoya’s Manhole Covers Turn Sewer Infrastructure Into Street Art
Nagoya decorates many of its manhole covers with pictures.
These pictures show things that are special to the city, such as Nagoya Castle, local foods, animals and samurai.
The covers make ordinary sewer equipment look like small pieces of street art.
A museum in Nagoya displays several of them.
One popular design shows an amenbo, which is a water strider that lives in clean water.
People helped choose some designs through competitions.
Other designs are created by artists or selected by city water officials.
Pokémon and baseball players have also appeared on Japanese manhole covers.
Some old covers are now collected and sold as souvenirs.
Nagoya has about 198,000 manholes across an 8,000-kilometre sewer network and nearly two dozen cover designs.
The designs feature local landmarks, food, wildlife, history, pop culture and civic events.
The Meta Water Sewerage Science Museum displays around a dozen colorful manhole designs.
Nagoya’s amenbo water-strider design was selected through a 1992 public competition and became a sewerage mascot.
Some Japanese manhole covers have become collectibles, including Pokémon covers and athlete tributes unveiled in Iwate Prefecture in 2025.
