Lindsey Taylor, Shou Sugi Ban: The Latest Trend in Fence Design; Transforming backyards, the scorched-wood technique from Japan is catching fire in America. Wall Street Journal, Aug 3, 2013.

("The Japanese art of charred wood—known as shou sugi ban—is making inroads in American landscaping. It's believed that the technique's Asian roots date to the 1700s, when the Japanese first started subjecting wood siding to fire as a way to preserve it. The charring protects the timber from sun, wind, water, decay and, yes, fire, greatly extending its life. Recently, American landscape designers and architects have begun playing with this seemingly pyromaniacal technique when it comes to fences, and loving the results")

The "ou"--alternately spelled as "ō"--is transliteration for a long vowel of "o."
(c) Cryptomeria
en.wikipedia.org/wiki/Cryptomeria
(a monotypic genus; "endemic to Japan, where it is known as Sugi 杉. The tree is often called Japanese cedar in English, though the tree is not related to the true cedars (Cedrus)")

Both Cryptomeria and Cedrus are the names of genus.
