Iida Nagano manhole cover（長野県飯田市のマンホール). Image by S. Morita (MRSY)

Anyone who has visited Japan has surely noticed the manhole covers, which each town and city designs to showcase local sites, famous products, and foods. S. Morita (MRSY) on flicker has gathered and geotagged photos of hundreds of these covers in his flickr album “Manhole covers マンホールの蓋.” The 382 photos cover Aichi to Wakayama, and there are even some from Korea.

What’s your favorite city for manhole covers? I’m quite fond of Nagano’s apricots and temari designs.
