In Japanese, 4 is pronounced in the same way as death (shi). They often skip numbering the 4th floor of a building or just skip the 4th floor altogether and go straight to 5 because of this. And Room 404 does not exist in maternity wards at hospitals because it sounds the same as the words for Infant Death, apparently.
