How do you map Korean Hanja sounds to Japanese Kanji sounds?


I think they’re related somehow.




For most Japanese Kanji, their _on’yomi_ sounds can easily be deduced from the
sounds of the corresponding Korean Hanja in a consistent and expectable
manner. The speakers of the Korean language, who have a decent Hanja
vocabulary, would notice that these _rules_ exist and take advantage of them
to figure out the sounds of Japanese Kanji words.
