A lot, I'm sure. I have no experience with Japanese but my wife is a native Chinese speaker.
1) In a language like English if you know a word and are faced with it's written form that you do not know you can probably figure it out. In Chinese knowing how to say it gives you no guidance in figuring out the written form, literacy takes years to learn. I have watched two literate Chinese speakers stumped by an unknown character and not even realize it was actually Japanese, not Chinese. (I knew because of the context, not from being able to read it.)
2) It appears to take my wife longer to write something in Chinese (and she's not a word-processor idiot by any means, when she's putting something into the computer she uses handwriting recognition, she's never learned the new ways) than it would take me in English--more strokes and they are less connected than even printing, let alone cursive.
3) Chinese lacks the concept of alphabetizing. I've watched her with her dictionary (we've been together since the 80s) and it's a process of looking stuff up in tables to get you close to your target and then a manual search once you're there. I can find a word in an English->Chinese dictionary far faster than she can find one in a Chinese->English dictionary.
That being said, I'm not going to call someone a word processor idiot because maintaining a skill like that costs time--it simply isn't worthwhile for most people. Many years ago I chose to abandon cursive when I realized that if I wanted to be able to write it decently I would have to deliberately practice--and I would say I write maybe a dozen words a month. Practicing would be a time sink, not a time saver. (Not to mention most of those words are on a whiteboard, too large to do in cursive.) Look it up is a perfectly good answer in most cases, only an issue for emergency type skills.
