Japanese manhole covers, which come in a variety of designs depending on locality, utility type and the manufacturer of the manhole cover, have caught the imagination of a growing number of "drainspotters" from around the world.

Japan's manhole covers often include a symbol specific to an area or town as part of the overall design. In Kyoto, a turtle (a symbol of wisdom and longevity) is the main motif, in addition local landmarks, festivals or flora and fauna can all be incorporated into these works of art under our feet.
