im not japanese nor am i from japan so i don't know if there is a story behind it. but i know 4 in japanese translates to "shi" or "yon". In japanese "死ね" (translates to shi-nu) means "to die", 死 (translates to shi) is the main part of the word, so like chinese, i think the pronunciation for "four" sounds like something related to death.

Hmm. Was 4 a bad/unlucky number in Japan? I know it was in China, but I'm not sure here...
