Here in “Nor’England” there are few tile roofs.
Over there, in Japan, are many.
I don’t know a lot about these roof tiles.
In Japanese they’re called “kawara”.
Here’s a link from someone who knows more than I do.

One of my favorites was a blue tile roof.
This one.
The house was just a few doors down from where we were staying.
In sun or shade, the color was gorgeous.
The rhythms of curves, circles, and lines make for great repetition, variety, and contrast.
Repetition, variety, and contrast, well handled, are the keys to good design.
Housewall and eave, rakeboard and tile, make angles and zigzags against the sky.
Here, the red clay body peeks from under its covering of cerulean glaze…
A roof like this can last well over a hundred years.
I don’t know how old this particular roof is.
But it will surely still be here long after I’m gone.

Tom, I so enjoy your blog and photography and often go it first before any other item that may be out there… Thanks so much!!
This roof is spectacular! Thank you. Was it a private house?
Yes. High class neighborhood. The house next door had a two-car garage. With a pair of Mercedes inside.
