Just a note...
The kanji are the spoken word, however they're pronounced. Different kanji, different word. Same kanji, same word.
On the contrary, we are talking about three different words in three different languages that mean three very different things. The fact that they are spelled the same does not make them the same word. You might as well say that lead
(verb) and lead
(noun) are the same word because they look the same on the page.
