Kanji question: the onyomi of 江 is found


The onyomi of 江 is コウ. Can someone give me a real-life example of when this is
read this way? It seems that most of the time its pronounced え... I should
also clarify, yes, I can look this up in a dictionary, but sometimes
dictionaries give you words that are obscure/rarely used by most people-- true
in any language, right?




In Japanese, 江 is read こう mostly in proper nouns --- in particular, Chinese
river names such as [長江]{ちょうこう}(Yangtze River) and [黒龍江]{こくりゅうこう}(Amur River)
and Chinese restaurant names.

In non-proper nouns, however, 江 is rarely read こう. 「[江湖]{こうこ} (meaning "rivers
and lakes" literally and "this (real) world" metaphorically)」 might be the
only exception but even that is not such a commonly-used word.

江 is a special kanji for me personally because that is one of the only four
kanji in the world that are used in my name (it is read え in my name, needless
to say) but even I do not know of any common or "everyday" kind of word in
which it is read こう.
