Ube City, Yamaguchi

One of the common manhole cover designs in Ube City on the south coast of Yamaguchi depicts Katta-kun, a Great White Pelican born in a local park that became quite a celebrity.

Tokiwa Park is also home to many swans, including Black Swans, and they feature on several other designs.

The city markets itself as " a city of greenery, flowers, & sculptures" pretty much on the basis of the park, but in fact, like much of the southern Yamaguchi coast, it is very industrial with refineries and factories producing chemicals, steel, and most famously, cement.

The official city flowers are Azalea and Scarlet Sage, but the center of this bottom design appears to be Iris.
