The average sentence in Japanese is represented in fewer characters than it would be in English.
Although obviously Japanese has far more characters to begin with, so they need to store more than our 26 letters (or 52 with capitals and lowercase). But in the end English takes up more storage space. There have been some cases in the past where part of the reason why a game didn't get a US release is because they would've had to increase the cart size and make it prohibitively expensive.
