Walking with your eyes fixed on the pavement is probably more interesting in Japan than anywhere else in the world. Here, nearly each of the 1,780 municipalities (the smallest of three administrative divisions) has its own unique manhole cover designs. They all share just two things: a circular or, more rarely, rectangular shape, and the way they're made.
But it wasn't always like this. According to Remo Camerota's book "Drainspotting", the idea of decorating manhole covers is relatively new.
The concept came about in the 1980s, when a government official working on the modernization of sewer systems in suburban and rural areas faced resistance from residents over the costly changes. As a "sweetener," they proposed decorative designs on the covers based on local symbols. The results of this initiative can still be admired today throughout Japan. There are so many decorative manhole covers, and they're so varied, that one could even explore the country following the trail of these covers without getting bored.
The most common motifs are nature-themed - especially trees and flowers, but also animals like fish, pandas, birds, sheep, hippos, cats, and even dinosaurs.
There are also scenic landscapes, especially mountainous ones, and urban views featuring iconic buildings or landmarks. Occasionally, you'll find covers depicting human figures, usually drawn in a "cartoon" style.
Many of the covers are monochrome, but the colorful ones are the most striking. Take a look for yourself and decide which ones you like best.
