Things I didn't do early on: collect manhole photos

I was in Japan many years before I started collecting photos of manhole covers. Manhole covers in Japan are like an art form. Most cities and towns have their own individual manhole cover design. Some towns and cities have more than one design. In some special places you can see numerous different manhole designs. And others again have "Poke lids" (Pokéfuta, ポケふた). 

What I love about manhole covers in Japan, other than them being pretty, is that, just like mascots, you can learn something about the area just from looking at the manhole cover. Often they depict the most famous thing about the area they are located.

Take for example the photo in this post. I took it in a rural area of Konosu City, called Kawasato, just last week. Straight up by looking at the manhole cover I knew that the area grows sunflowers. A quick internet search confirmed that, while not a major producer, sunflowers are grown in the area. Moreover, before the area merged with Konosu city, the sunflower was the flower of Kawasato. In addition, the osmanthus is pictured because it was the tree of the town.

Do you collect manhole photos?
