Manhole covers (マンホールの蓋)

Soon after you come to Japan, you might find fancy manhole covers like the above picture. They are called "design manhole" in Japanese, and there are so many designed manhole covers all over Japan. I suppose that there are 2 to 5 kinds of designs of manhole covers in each town! Many of them are only iron colors, but some of them are colored. I don't know why Japanese people are into such a trivial thing ... Although, it's interesting.

But don't addict too much to find them while your trip, or your memory of the Japan trip will be filled with gray ground scenes!
