Manhole covers don't have to be ugly sewer lids. In Japan, they can be astoundingly intricate, colourful, museum-worthy feats of urban design.
Photographer S. Morita (Flickr name MRSY) has snapped over a thousand manhole covers around Japan over the years. In a country renowned for its attention to detail and rich artistic heritage, it's pretty inspiring to take a bland city staple, that people literally walk all over, and morph it into eye candy.
Head over to Morita's Flickr page for hundreds of more photos of these pavement-topping beauties. JapanVisitor.com has photos on their own site, too, and there's even photographer Remo Camerota's coffee table book.
Sometimes the coolest stuff is just under our noses...and our feet.
