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.
I have really started to get into finding interesting manhole covers as I walk around in Japan. The one above is from Matsue City, Shimane, and shows a giant stone lantern on the shore of Lake Shinji.
Tsuwano Town, Shimane. The town is famous for the giant carp in its waterways and laid-back Edo period atmosphere.
