One of the most common ones I can think of off the top of my head is 嘘, I have never seen it used in its On-yomi form and have only ever seen it pronounced as うそ. Are there any other Kanji like this, where the On yomi is rarely used, or even doesn’t exist? I’m not counting Kokuji characters that were invented by Japan and used only in Japan, since obviously those characters typically won’t have Onyomi.
