I have already mentioned manhole cob\evrs in Shimizu Ku, Shizuoka City.
This is a very large area indeed and it tends to mix all kinds of covers since it was merged with Shizuoka City.
But if like me yesterday you happened to cycle along the Miho Beach, especially along the parallel streets running through urban parts you will find them concentrated in large numbers!

I will describe them in the order I found them!
two together there!

A cover belonging to Shimizu City before it was merged!
This type is for river water collection.
There is another type with the same design!

Another Shimzsu City type with azaleas dating back before the merger!
Actually all do in that particular area!

Typical rectangular fire hydrant access cover!

An unusual double cover with the Miho beach design for rain water!

Those two different fire hydrant access covers are typical of Shimizu City!

The second type with the Miho Beach design for rain water!

A geometrical design sewer cover with the Shimizu City symbol in its center!

Another geometrical design for rain water collection!

Pressurized air access!

Another geometrical motif sewer cover!

Shimizu is soccer land!
A medium-sized orange valve access!

The same, smaller and blue!

A fairly complicated cover which could be opened in many ways!

The most famous fire Hhdrant cover in Shimizu with soccer players!
