When you walk around, are you only looking at the scenery or do you look down at the ground sometimes? Well, in Osaka, I've found that you should look down at the ground. No, you will not find money on the ground (rarely will you ever!), but you will be able to by-pass all of the poo that is left by many pooches' owners (who are too lazy to pick it up...shame on you guys!) and you'll also see some interesting manhole cover art.
Rant aside...This is the manhole cover for our city, Minoo. It features our waterfall, Minoo-taki and the momiji (maple leaves) that Minoo is famous for.
The city next to us, Ikeda, has a picture of a bird. Someone handpainted this one, which makes it a little easier to see.
And from another neighboring city, Suita, the expo of 1970's symbol is in the center called Taiyonoto or Tower of the Sun, which was designed by an artist named Okamoto Taro.
I also found an interesting Japanese website which lists photos and a little explanation of all the manhole covers of all the cities within Osaka prefecture here (actually when you look through the whole site they list most of the manhole covers for the different prefectures throughout Japan and a few abroad!)
Pretty interesting stuff!
